July average maxima in San Francisco coolest since 1971

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?

Now let’s rank the values you posted by year (I would love to have the full dataset, but this is more than enough):
…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….

However the San Francisco temperature record seems to exhibit a heat island effect when compared to the records of less populated areas.

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.

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

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.

Dang spellcheck, meant climatic … jeez.

I’ve been saying it was cold here…
@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.

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.

Codetech: We in Toronto do not believe we are the whole of Canada—we are the centre of Canada!
Here we’re having an average summer, and much better than last year. A few hot days, some humidity, generally just the way I remembered them. If NOAA or GISS shows that it was abnormally high in July, I’ll know the fix is definitely in.

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.

Scotland, yes.
How did u guess?
Been wondering why global warming wasn’t noticeable here. With WUWT now I understand.
Huth

GM,
you are new here. so, i understand your consternation.
everyone here DO believe weather is not climate. you will find that out, as you read the posts here for a while.
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.
Context , my friend, is quite important
