July average maxima in San Francisco coolest since 1971

Supposedly Mark Twain once asserted: “The coldest winter I ever spent was a summer in San Francisco.” This July was cold, and Twain’s quote? Well, read on.

My friend Jan Null, former lead forecaster for the NWS in California, is now runs a private forecasting and forensic weather services business. He sends out regular emails with note of interest. Here is one of them:

With an average monthly maximum  July temperature of just 63.1 degrees, San Francisco had its coolest July since 1971 and the 13th coolest in the past 97 years.  Only one day reached the 70 degree mark (72 degrees on 7/3 and no day after the 17th exceeded 64 degrees.

another nail in the coffin of the ASFW alarmists!!

August 2, 2010 9:50 pm

Wasn’t 1971 cooler (62.68) than 1970 (63.13), which would require another caption for the entire entry?

yes a typo in the title, fixed. Thanks Anthony

August 2, 2010 9:54 pm

I doubt any of us will still be alive the next time there is a “hottest year on record”.

August 2, 2010 9:54 pm

Now let’s rank the values you posted by year (I would love to have the full dataset, but this is more than enough):
1914 62.06
1919 62.9
1920 64.1
1924 64.71
1927 64.77
1928 64.42
1930 65.06
1937 64.39
1938 63.32
1939 64.42
1941 64.94
1942 64.68
1943 63.9
1944 61.55
1945 64.13
1948 64.87
1949 63
1950 63.03
1951 61.13
1952 63.94
1953 63.87
1955 62.52
1956 61.9
1958 63.55
1960 63.39
1962 60.52
1964 64.61
1965 61.94

So out of the 45 coldest years (which is probably 1/3 of the dataset) only 5 (1/9th of them) are in the last 30 years….

Yet again, the alarmist MSN in Australia reports mostly events like heatwaves in Russia, forest fires in Southern California and floods in Pakistan, they don’t mention it, but you can feel it, the pro-AGW slant. But cold, is just weather, right? Well, maybe not, yesterday there was one 30 second report of an “antarctic blast” dumping quite a bit of snow in the Blue and Snowy mountain areas. Bumper snow season in Australia and New Zealand this winter.
The election is on Ausgust 21st (And as it turns out, I don’t qualify to vote! Well if I had sorted out my citizenship before Ms Gillard pushed KRudd747 aside via a sturdy knife in the back and pulled an early election, I might have. Oh well! 3 more years! 3 more years!) and if Labor form a coalition with the Greens, very probable, we can say good bye to the lucky country. All manner of “planet saving” legislation is just waiting in the wings. Incidentally, almost 1.5 million new voters registered to vote this year. Will be an interesting election.

From the link to Snopes.com: It may be California, and it may be lovely, but the wind can be vicious, and those summertime temperatures can be disappointing bordering on “in danger of freezing if one doesn’t keep moving.”
The alarmists will shortly need to be moving from a canter into a gallop…

Makes me miss Herb Caen.

Anthony, trivial but Jan overlooked 1971 (#8) as “coolest July since”.
REPLY: No that’s an error on my part in copy paste, and writing the title, Fixed thanks. -A

August 2, 2010 10:28 pm

As far as I can tell it was absurdly cold and gloomy in San Diego in July too. Fricking Brrrrr!

August 2, 2010 10:37 pm

My read of the above table is that it’s the coolest since 1971, position 8 on the list, since 1970 was a bit warmer than 2010. When one says “coolest since…” it refers to time when it was colder. But you, Anthony, have shown a year that was a bit warmer than 2010.

August 2, 2010 10:45 pm

you should give the unit (°F) for Avg. Max column.

in the USA, it is assumed, and if those were C, people would be screaming about a heat wave -Anthony

August 2, 2010 10:51 pm

But — but — but — it was the 28th *warmest* July evah!
The post above is one reason I like to see the actual temperatures, rather than a graph of anomalies. When the difference between the warmest and the coolest is less than four and a half degrees, it puts some perspective back into the discussion.

I was alive 34 of those 45 years and I didn’t notice because cold and foggy is normal. I did notice the unusual warming period that ended about three years ago. For me, normal is cold and foggy between the spring and fall heat waves.

Nice bit of cherry picking.
REPLY: Noting records or events in context of records is not cherry picking, they are singular points. Either they exceed +/- previous records or they don’t. For example:

430 AM PDT FRI JUL 10 2010

But you can be certain that if it was the warmest July SFO maxima since 1971 it would be screamed about it headlines.

San Diego had it’s coolest July since 1933! It ranked 14th all-time for coolest July, which is impressive considering the changes in locations and the urban growth that downtown San Diego has experienced in the last 77 years.
There were only 8 days with a high temp of 70 or above, compared to 9 in January!
I wonder how much money this cool weather has saved people on their electric bills? While the immediate coastal areas benefitted the most, inland areas have also been running at least 10 degrees below normal too – and that’s a good thing for them.

August 2, 2010 10:58 pm

Well Anthony, you are the hero who blogs in his spare time even when he is tired. I have my own blog but when I’m tired I just say: “I’ll leave it till tomorrow” and two to three weeks later it gets done!
Second, I notice that we skeptics air our dirty laundry in public — if we make a mistake it is out in the open and so is the retraction. Unlike AGW. Kudos…

I work in a building on the old naval air station in Alameda. Our shop Is on the lagoon with windows facing the city. The summer fog has been very persistent, burning off back to the coast by 10:00 to 11:00, rolling back in by 4 or so (ruining all the sunsets) I was over there on top of the hills a couple of times last month, streets wet, trees dripping with water, very windy. Makes for excellent sailing in the afternoons!

August 2, 2010 11:00 pm

I’m not cruel, but every physical value requires its unit. I’m living in Germany and the people would be there screaming about a new heat wave…in the USA 😉

Something in the Bee this last Sunday related to this;
Mild weather, summer breezes keep ozone low

No sweat. Breathe easy.
Mild temperatures in the Sacramento region this summer have meant something more than freedom from perspiration.
Cool weather has brought better air quality, and fewer respiratory problems for those who suffer when ozone levels rise.
The Sacramento Metropolitan Air Quality Management District has declared just two “Spare the Air” days this summer – days when air quality reaches unhealthy levels.
Every other year this decade, officials have declared at least five by this date, and sometimes as many as 13.
This year’s two dates, July 16 and July 17, also came much later in the year than is typical.
“We’ve had a really wonderful summer for people who are troubled by bad air,” said Christina Ragsdale, spokeswoman for the district.
The quality of the air is related to the heat, or lack of it.
Ozone forms when a soup of volatile organic compounds – a variety of gases – is cooked by high temperatures and oxygen bonds into three-atom molecules: ozone.
That’s why in July 2006, when Sacramento had a record 11 days in a row with highs above 100 degrees, it had nine “Spare the Air” days in just those 11 days.
Temperatures have reached 100 degrees or higher six times this July in Sacramento, but those days have been spread out over the month.
Another key factor has helped prevent the buildup of ozone this year.
“Even when it’s been warm, we’ve had a lot of wind,” Ragsdale said. The wind slows ozone production.

How do you like “Spare the Air” days as climate marker?
See the graphic Fewer Bad-Air Days for Sacramento. Annual total bad air days by year from 2001-2010.

You should lead off with “NOAA once again shows that this year is not breaking the trend of lower global average temperatures” then give the anecdote “for example, in SF, it’s been an unusually cold July.” Go from the broad data set to the sample, so as not to appear to be cherry-picking. I mean, unless the larger data set stands in your way.

Over here in Perth, Western Australia, the month of July had average minimum daily temperatures of 5.9C as against the long term average minimum for July of 7.8C, almost 2 whole degrees less! Mean maximums were “normal” with the July just gone averaging 18.2C compared to long term average of 18.3C.
Similar for June 2010 – average min of 7.1C compared to long term average of 8.4C but average maximum was 19.0C compared to long term average of 19.3C.

August 2, 2010 11:58 pm

Hang on just a minute, those temperatures haven’t been homogenized yet !! Im sure once they are properly processed they will be the 3rd hottest on record.

August 3, 2010 12:07 am

What would the real temperature be if a correction was made for the UHI?

August 3, 2010 12:09 am

The weather in SF is mainly a function of wind direction. When the winds blow onshore, it is cool and gloomy. When the winds blow offshore, it can get hot. San Francisco’s hottest days are generally September and October when we get the wind from the East and the downslope winds from the Sierra warm things up.
That said, I live a ways South (about 50 miles) from SF and have a coastal range of mountains between me and the coast (Santa Cruz mountains). We are generally warmer than SF and not as influenced by the coastal marine layer. Not this year. It has been cool and gloomy in the mornings with a late burnoff of marine layer of clouds/fog in the mornings. Temperatures have been below normal even here. But again, we haven’t had any strong Easterly winds to push the temperatures up either.
We will see how it goes in the fall.

August 3, 2010 12:21 am

Don E: that sounds like west of Scotland weather. Or do I mean climate?
Anthony: Brits read this and don’t assume anything, least of all units of measurement. Please specify your units, °F in this case. We’d like it even better if you could summon the energy to be ‘global’ about this and use °C (maybe as well rather than instead of). More work, I know. Just asking.

August 3, 2010 12:51 am

Gail Combs:
You can not compare SF with Electra or Yosemite or especially Independence. Those cities are in completely different climactic regions. Yosemite Park HQ is in a valley in the Sierra Nevada mountains. Electra is in “gold country” also in the Sierra foothills. Independence is on the other side of the Sierras near the Nevada border.
One would have to compare San Francisco with places like Half Moon Bay, Santa Cruz, and Bodega Bay. You will want to compare other coastal areas to make sure you get apples to apples.

Dang spellcheck, meant climatic … jeez.

August 3, 2010 1:10 am

I’ve been saying it was cold here…
Today I ripped out one of my tomato plants. Type name was “San Francisco Fog” and was supposed to be cold tolerant. The Siberian was making tomatoes, but not the SF Fog. Guess we are “Siberia” cold now 😉 That’s what I’ll be growing from here on out (along with the similar “Siberia” variaety). Of interest, the Roma planted next to the Siberian is also making fruit, but with only a few seeds. I think the Siberian is acting as a cold pollinator. (It’s pollen grain growth that’s limiting in the cold…)
@GM: If you had a point, a long list of numbers showing this year was cold, and about as cold as other Way Cold years, didn’t seem to say much other than: Its COLD.
Oh, and I’m sure we’ll have LOTS more cold years going forward now that the PDO is flipped back to ’70s mode’ and the sun is on vacation.
@Tom: SFO has water on three sides and frequent winds. It’s the odd day that has smog build up at all. (It generally all gets blown down the peninsula to where I live 🙁 or gets sent over to Oakland… ) So most of the time SF temps match the water temps plus solar heating minus wind speed… Smog need not apply.
@Crosspatch: We’re probably not too far apart. I’ve had it be 103 F down here and 55 F under the fog in SF. Shocking when you leave here for there and forget to take a coat. Now anytime we head to SF, we put a coat in the car. And this year I’ve had overcast until late morning, then back again at near sundown. Dank and cold.
To those folks kvetching about the use of F: It’s what we do here. To convert it to C Anthony would have to change the published data and take precision errors. F is more precise than C, so something would be lost in the conversion. How about you learn to be multi-lingual in temperatures? We are… I use C, F, K, and even R sometimes. Depends on what works best. And F works just fine. BTW, the “traditional” units were not as slap-dash has legend leads you to think.
Take the planetary circumference in feet at the equator (131479724.6). Divide by (360 x 1000).
Recognize the number?…
Mark a circle on the ground and put a stick in the ground at the perimeter aligned with a star rising at the horizon. Put another stick 15 degrees away (you can do that without advanced tools…). Time the transit of a star from the first stick to the second with a pendulum. Count 3600 beats. Lengthen or shorten until it is exactly 3600. Congratulations. You have a 1 Rod measure. You can create this length standard anywhere with 2 sticks and a bit of string…
The old units are Just Fine. And I’ll be able to recreate them anytime I want without any government body and without doing a survey of France… and getting it a bit off (the M is a bit off, but you knew that already…)

The point of the post was to show that the original post was dishonest, which should be obvious to
[snip — behave politely or take it elsewhere ~ ctm]
because I have figured our a long time ago that there is nothing to gain from that as the only weapon I as a scientist have are facts and logic and it is impossible to argue with facts and logic with people who do not see any value in those. And I am not a climatologist myself but I happened to come here by chance and I was about to scream in horror when I saw that post, so obvious is the hole in the argument. I can imagine how a climatologist would feel…
Anyway, yes, that’s the current temperatures in San Francisco maybe relatively cold. And what this means is precisely that – it’s cold in San Francisco and it hasn’t been very hot in Southern California where I am either . Which is only relevant to the argument about global climate change as far as the contribution of California to the global annual temperatures goes. Which is very small.
The same is true for the US as a whole. Another recent post was showing the map of the US and the how “cold” it is in the southern parts – that the northern part of the US are hotter than usual and that the whole of Canada is much hotter than usual was left out. Not that those on their own prove that there is warming, but this blog seems to only focus on the colder than usual regions, I wonder why.
The worst thing is that these same tactics have been beaten down to death repeatedly, yet nobody seems to listen…

“The whole of Canada” was most certainly not “hotter” than usual. Unless, as some Torontonians seem to believe, Toronto is suddenly the whole of Canada.
It’s COLD in the west. Stupidly cold. We’ve had a few days with high peak temps that are rapidly cooled in the late afternoon. We’re a month late on our usual weather patterns. We are missing summer, and this bodes ill for the winter to come.
Whatever you’re yapping about (GM) that’s getting you snipped, your accuracy certainly seems to be lacking as well. I’m not hearing anyone in BC, Alberta, Saskatchewan or Manitoba talking about “hot”, and that’s half the country.

I think that the most accurate thing that can be said from the (partial) dataset is that the average July temperature for San Francisco is in the range of 60-65 deg. F and has been in that range for a century.

The local meteorologist for Redding was heard to remark that it is ‘very unusual’ to have a delta breeze in the forecast for 2 weeks straight. He normally gets the charts for that phenomenon out a couple of times per year.
So, the Delta Breeze coming in through SF is stuck in the ‘ON’ position.
Just like the last 3 years, where weather patterns get stuck. Same story with the recalcitrant Sun.
Yes, I do blame these stuck phenomena on the Sun.

this post does not stand on it’s own. It is part of a complaint about the MSM. MSM has been talking up “hot Moscow”, and ignoring “Cold Siberia”. and MSM did not talk about “cold South America”, where there were snow on the beaches of Northern Argentina, which generally does not see snow.
MSM has been making a big deal out of Hot NY/Wash.DC/Phila,PA etc. but ignoring cold SanFran etc. That is what this post was about.

Don’t be silly. 2011 will be the hottest year on record. And then it will be 2012, and then 2013…
I predict it will be the hottest right before every election cycle.

It’s my understanding that in the 1970’s Climate Scientists were telling us that we were probably entering a new Ice Age.

i have been following the cool summer thing, but i just got back from the eastbay and was shocked at how cool it was even there, beyond the fog.
in dublin it was barely 80F and quite chilly at night. i believe that must be 20F below normal!
kind of like our april, may and june over here in the eastern sierra.
i did not check the actual temp but the central valley did not seem so bad either, it was warmer in the foothills. the cool ocean air is really doing a job.

That’s because there is a new neighbour in California, cold follows him wherever he goes….

Try to live each and every minute of this summer……you will miss it!

From the NASA GISS personnel blurb for Dr. Hansen,
in his own words…(my bolding)
One of my research interests is radiative transfer in planetary atmospheres, especially interpreting remote sounding of the earth’s atmosphere and surface from satellites. Such data, appropriately analyzed, may provide one of our most effective ways to monitor and study global change on the earth. The hardest part is trying to influence the nature of the measurements obtained, so that the key information can be obtained.
Pretty much sums it all up, I daresay.

You’re right. And the cold from Antarctica already tried to reach up to Mexico… Cancun is coming, and probably Al wants to visit…

Isn’t it valid (according to ‘climate scientists’) to extrapolate one temp up to 1200 miles away?
Both Yosemite and Eureka are far less than that and also within the 250 mile limit used by other ‘climate scientists’.

I’m sure I was taught that if you could remember Frisco in ’71, you weren’t really there.

“Dang spellcheck, meant climatic … jeez.”
But you’re also right when you say they’re in different CLIMACTIC regions. 😉
I usually ignore daily records in the US as being fodder for news bunnies. Records in relatively short series of a century or less are destined to be broken quite frequently. But with monthly records that amount to the coldest in 77 years (as in coastal San Diego, where the population was an order of magnitude smaller back then), we cross over into the realm of possible harbingers of a significant climatic swing, driven by oceanic cycles. I’m waiting through 2012 for confirmation, however. (Meanwhile, anything on climactic swinging is best left unsaid.)

Cold summers, earthquakes, radical politics and no good beaches.
Why would anyone want to live there? I guess maybe if you like those things…

Many areas of the globe are seeing unprecidented cool weather.
But just the same… Anyone willing to jump in on a wager that July will still end up to be one of the hottest on record ?
… as will August
… and September
… and October
etc etc
(of course they’ll toss in the odd cool month every now and then just to throw us off the scent of the trail)
Mighty good thing those surface station sites are all slowly getting closer and closer to the equator, otherwise the climatologists might be forced to sing a different song. And that just wouldn’t be good for cap and trade, now would it ?

Just returned from visiting family and friends in Southern California. North Orange County beaches (Huntington & Bolsa Chica) were very cool in the mornings with overcast/cloudy skies that didn’t burn off at all. Water temp was a chilly 63 degrees.
My friends and I have surfed southern California beaches for the last 30+ years and don’t remember the ocean being this cold so late in the season. Cloudy/overcast skies are typical “June gloom” along the coast into early July. This year the “gloom” has lasted into late July/early August.

Here in Brazil we had -10°C in some cities of the south, and for the first time some cities experienced snow, but all we see and hear is about Russia and their heatwaves
