Of course, there was also some high temperature records set too, for example in Seattle

Northwest dries out in record triple-digit heat (AP)

http://www.ajc.com/news/nation-world/northwest-dries-out-in-103724.html

The National Weather Service in Seattle recorded 103 degrees at Seattle-Tacoma International Airport, breaking a previous record of 100 degrees, set in downtown Seattle in 1941 and repeated at the airport in 1994.

The placement of the ASOS thermometer may have contributed to that high temperature record.

See this map, the red/white striped pole just left of the runway is the ASOS anemometer and wind vane mast. The temperature sensor is on the NW to SE line of dots. Airports do tend to run warmer.

Our weatherman in the Dayton/Cinci area of Ohio told us that it was the coldest July on record, and then retracted it after Accuweather recalculated the numbers. It was the second coldest July on record. By .04ºF.

Jack Barnes

As someone who lives in Southern Oregon, I can state, that YES it was that Hot down here… give or take a few degrees. It was foggy and 70 degrees on the coast, and 109 or hotter in the valley. Until this burst of heat, we have had an extremely cool spring and summer. We just pulled our pea plants due to this last surge of heat. The Garden is confused this year.

Douglas DC

In NE Oregon we are finally having summer,100F yesterday in LaGrande.Tomatoes
finally setting fruit.Makes me wonder that this weather-more like August -isn’t
a pattern change that wil result in an early fall-just as the tomatoes near ripening!
Spent lots of time in the 90’s fighting fire out of Medford. Lived in Port Orford, couldn;t
wait for day off and cool coastal weather….
Less humid in La Grande ,heat’s a bit easier to take…

rbateman

If you take the weather records for the Pacific Northwest and subtract a few degrees for UHI, they match up nicely for June29-July4th 1942.
Many gardens here in NW Ca are reporting problems. Fine line between weak growth/burned up from not enough/too much sun.

rbateman

Douglas DC (14:19:27) :
Long range forecasts are saying just that, Doug. Early fall.
If the weather cools prematurely, try putting some rocks around the tomatoes. Anything to boost the daytime heat. In this 2nd year of weird climate, we are expermenting heavily to keep the production up.

Terry

Having just returned from a week in NW Ontario (about an hour north of International Falls, MN) I can only say – turn up the heat… please!!!

July was hottest in city’s history By Jamie Klein –
San Antonio Express-News 08/01/2009 12:00 CDT
It should come as no surprise to anyone who stepped outdoors last month that July’s daily average temperatures lit the city’s records on fire. Not only was it the hottest July on record, it also was the hottest month — ever.
Since May 1, San Antonio has recorded 35 days of 100 degrees or higher, 22 of them in July.
The stretch of what feels like never-ending heat has been caused partly by a summer subtropical high hovering over North America, suppressing rain formation, said Robert Blaha, a meteorologist with the National Weather Service.
And the absence of rain means little moisture on the ground, which then causes warmer temperatures — with seemingly no relief in the immediate future.
Blaha said the past 23 months, from September 2007 through July, have been the driest the city has ever recorded.
“It’s been so dry in the area, and that helps things heat up much more efficiently,” Blaha said.
________________________________________________________________
I suspect that UHI had a helping hand, as well as the continuing drought.
” the hottest month — ever” above should have said “since 1942”, when the station had a significant move and screwed up the 122 year dataset.

Google 2009 “coldest July” temperatures: 17,000
Google 2009 “coolest July”temperatures: 14,000
Google 2009 “average July” temperatures: 27,000
Google 2009 “warmest July”” temperatures: 15,000
Google 2009 “hottest July” temperatures: 7,000
Not a scientific study. The “-est” suffix on these words tends to be used in the past tense, so that clause avoids many predictions. It is necessary to mention temperatures to avoid picking up every other report of “average July” statistics. If the year is omitted the result includes past years, although it is probably skewed toward the recent periods due to older pages being removed for various reasons.
A Google Trends search which compares popularity of searches; 2006 had a peak of searches for the hottest July.

You aren’t showing the whole picture, Anthony, unless you put up an article about the insane, hellish, unbelievable, historic drought/heatwave in Texas.
I’m so envious of others for their cool summer. Ours has been insane, hellish, unbelievable, historic – and altogether horrifying.
Oh, and the drought here only makes matters worse. I, for one, am PRAYING for El Niño to come, because we need some precip!
We have had 3-week stretches of 100+ here in San Antonio in August, but nothing like this year in my memory!

Gary

Wettest July on record in RI by 20% over the old record.

Ted

The “Arctic Blast” gave Portland, Oregon its highest December snowfall ever, and a huge ridge of high pressure extending to the Yukon resulted in Portland tying its highest recorded temperature.
I wonder what role, if any, the sunspot cycle is playing in these localized events?

Conner

Buffalo ended up with it’s 2nd or 6th (airport versus waterfront, which is significantly colder) coldest July ever. It also ended up with the 2nd coolest June-July combo, a tie for coldest maximum temp through July (85F), fewest 80F+ days through July (9 vs a normal 32), a tie for the fewest 86F+ days through July (0 vs a normal 10), and the fewest cooling degree days through July (154 vs a normal 336). Rochester(NY) ended with it’s 2nd coldest, with the coldest being in 1884. It also has it’s coolest June-July combo ever, coolest yearly maximum ever through July (86F), fewest 80F+ days through July ever (12 vs a normal 35 and the previous record of 15), the fewest 86F+ days through July ever (1 vs a normal 15 and the previous record of 2), and the fewest cooling degree days (144 versus a normal 356). It will be interesting to see August. Me thinks I smell a 1976-1977 coming on… The similarities are numerous.

Interesting that central Alaska is warmer than much of the midwest. Great summer for biking and working outside.

July 2009 sets record for temperatures
By Juana Summers
AMERICAN-STATESMAN STAFF
Saturday, August 01, 2009
July 2009 goes down as the hottest month ever recorded, Lower Colorado River Authority meteorologist Bob Rose said Friday.
The previous record, with an average daily temperature of 89.1 degrees, was set in July 1860. Last month, daily temperatures averaged 89.5 degrees.
July 2009 had 26 days with temperatures over 100 degrees, and 42 days saw triple-digit highs so far this summer.

Please publish the NOAA temp deviation map for July when it comes out.
I’m feeling some yellow and brown spin art, a “3 warmest July on record” press release, and “despite what you may have felt” doublethink news shills tossed in there.

Yes, it is happening in Canada too :
“Most of Canada – with the exception of B.C., Yukon and some parts of Atlantic Canada – are experiencing colder than normal temperatures this summer.”

We had few hot days here in Oregon and local warmist and recipient of a NASA grant says:
http://www.oregonlive.com/opinion/index.ssf/2009/08/climate_change_teachable_momen.html
“I’m always looking for teachable moments, and eagerly await the day when TV meteorologists use their relationship with the public to communicate the science of climate change.
This heat wave is just such a teachable moment.
I haven’t seen a single mention that this kind of heat wave probably is going to increase in frequency in coming decades. Not every year, but the likelihood of this kind of heat wave and worse occurring is increasing over time. Isn’t that something that viewers would want to know? Couldn’t that information lead to informed decisions, such as to invest in ceiling fans or the kind of heat pumps that provide the most efficient air conditioning?”
[A near drowning story filled the bulk of his commentary, then]
“If the boy had drowned, I would have been haunted by his death and my inaction forever.
Climate change and related issues could lead to situations as serious as the boy faced, only many, many times over. And by not saying anything when we could, those of us in a position to speak about how serious climate change is will feel as I did, only far worse. If not us, who will speak? If not now, when?”
Richard Brenne is a writer and film and event producer living in Southwest Portland. He is co-moderating an online class called Global Climate Change through Portland Community College with a grant from NASA, and is organizing a series of town meetings to discuss climate and energy issues at Portland State University.
There’s a comment section at that linked oped piece.
Take a look.

Robert Wood

Here in Ottawa we’ve had our coldest wettest July EVER … well, since we’ve measured these things.
It was obviously colder when this city was under a couple of kilometers of ice; and wetter when that ice melted – google The Ottawa Embayment.

Robert Wood

rbateman, We have, here in Ottawa, had almost continual 100% cloud for this “summer”. This means less heat in the top layers of the Earth soil/rock. Therfore, there is les heat stored and it will become winter earlier.

layne Blanchard

Ah ah ah! No talk of early fall! This is the only decent summer I’ve ever seen here in the NW. I’m savoring it. Everything will turn to crap soon enough.

As I went for a walk this week and saw the fog blowing across a nearby road in early afternoon, I thought What a nice California winter day!
Only trouble is, it’s summer.

Ron de Haan

According to Joseph D’Aleo the North is experiencing a volcanic summer (4 medium sized eruptions this year), negative PDO and the current Solar Minimum.

I believe NOAA intended that to read “most beautiful freakin’ summer ever in Grand Rapids!” Seriously, I’m hoping for a change in the jet stream next month that would leave us in the mid 70’s for 5 straight months, June to October. Michigan is gorgeous at this temp.

Gene Nemetz

A year without a summer in Korea too :
“In Busan, where Korea’s most popular beaches are located, temperatures did not rise above 30 (C) degrees for a single day in July, as against seven days in July last year… low temperatures is more serious on the east coast… the average high temperature in Gangneung city in July was 26.7 degrees, 3.6 degrees lower than last year… Temperatures are expected to continue cool in early August. ‘It is customary for Korea to see the hottest temperatures of the year between the latter half of July and the first half of August…’ ”

Last night in Rockford, Illinois I saw a temp reported by Weather Bug (on my computer screen) of 52 F. Unseasonably cold to say the least. We got some 90F temps in April. Which was unseasonably warm to say the least.

Julie L (15:02:23) :
You aren’t showing the whole picture, Anthony, unless you put up an article about the insane, hellish, unbelievable, historic drought/heatwave in Texas.

Please; the state of Texas is a large state and *not* all quarters are suffering the same fate.
We here in Noth Central Texas certainly are not! (DFW area including the cities of Dallas, Ft. Worth, Arlington, Denton, McKinney)
Some specificity next time please.

MattN

As cool as it was in the central and NE USA, I expect July to be bleow normal for the US. However, AMSU-A showed extraordinarily high temps. Record high, in fact, for some days. Globally, it appears to have been quite a warm July, significantly warmer than last July.

Gene Nemetz

Julie L (15:02:23) : the insane, hellish, unbelievable, historic drought/heatwave in Texas.
There have been worse droughts.
The earth is in a cooling trend.
What is happening in Texas is ‘weather’. Also, don’t discount Urban Heat Island (UHI).

Gene Nemetz

_Jim (16:30:28) :
Julie L (15:02:23) : Some specificity next time please.

I wouldn’t expect specificity from commenters like Julie. The specificity you are asking for would make render her comment powerless.
Julie is trying to create hysteria—i.e., the sky is falling!

Mark Wagner

here in Dallas we had two weeks of rain in July and hi temps (only) in the 80’s & 90’s. Both unheard of for a N. TX July.
Back to 102 on Monday, though. Ahhh….that’s more like it.

geo

Upper midwest has been unseasonably cool almost all summer. I’ve taken to calling summer “a pretty nice spring” this year. Even NOAA admits that.
Meanwhile, NSIDC felt a gleeful need to have a breathless mid-month alert on July 22 about 2009 Arctic ice extant dropping below the 2008 trend line, while neglecting to mention this merely put it on the 2005 trend for this time of year. Well, the next two weeks will be interesting indeed, but the last two days might have the hairs standing up on the back of their neck a little. At any rate, it is now really time to see what we’re going to see about Arctic ice for summer 2009.

Richard M

As indicated many times it has been quite cool here in the midwest. Locally we set a record for the lowest ever high temp in July (83). Overall it was the second coolest July. The air conditioner has had nothing to do since a couple of days in May. The first week of August is forecast to remain below normal.
However, I have noticed some of the weeds along creeks and roads are bigger than ever. They must really like the cool temps and/or abundance of CO2.

Bruce

Hoytn and Schatten in their 1997 work,”The Role of the Sun in Climate Change”, list a number of factors on p87 that can cause problems with getting proper temperature readings. Airports also have large jet engines blasting hot air around that has to have an effect on temperature.

… NASHVILLE EXPERIENCED ITS 4TH COOLEST JULY ON RECORD… AND THE WETTEST JULY SINCE 1984…
THE TEMPERATURE DURING THE MONTH OF JULY IN NASHVILLE AVERAGED 3.4 DEGREES BELOW NORMAL… MAKING IT THE 4TH COOLEST JULY IN NASHVILLE AND THE COOLEST SINCE 1967. THERE WERE 6 LOWEST DAILY TEMPERATURE RECORDS… EITHER TIED… OR BROKEN DURING THE MONTH.
THERE WERE ONLY 4 DAYS DURING THE MONTH OF JULY IN WHICH THE TEMPERATURE REACHED OR EXCEEDED THE 90 DEGREE MARK. THIS TIES THE ALL TIME RECORD ALSO SET IN 1967 FOR THE FEWEST DAYS WITH 90 DEGREES AND ABOVE DURING THE MONTH OF JULY. THE WARMEST TEMPERATURE DURING THE MONTH WAS 92 DEGREES ON THE 15TH… AND THE COOLEST WAS 57 DEGREES ON THE 19TH.
THIS WAS THE WETTEST JULY IN NASHVILLE SINCE 1984… AND THE 22ND WETTEST OUT OF THE LAST 138 YEARS THAT RECORDS HAVE BEEN KEPT. RAINFALL FOR JULY 2009 TOTALED 6.03 INCHES WHICH IS 2.26 INCHES ABOVE NORMAL. NORMAL RAINFALL FOR JULY IS 3.77 INCHES.
THE FIRST FULL YEAR OF WEATHER RECORDS IN NASHVILLE DATES BACK TO 1871.

The inland Northwest is having high temp records fall to new high record temps all over the place. In a week we will be back to 80’s though. Night time temps are still lower than average and are causing corn and tomato plant problems.

Paul Vaughan

Vancouver International Airport (British Columbia, Canada) recorded the highest temperature *ever* recorded *last* week (according to a local radio station). There have been fires even near the coast. I have not stopped dripping buckets of sweat in weeks (but the trend has finally switched to gradual cooling).
By sharp contrast, the past 2 years here have been comfortably cool (considered “unusual”). 2003&4 were scorchers (considered “unusual”). 1999 saw record local-mountain snowfall (considered “unusual”). 2006 saw record winter-winds (considered “unusual”). A few short months ago it snowed continuously for 3 straight weeks (considered “unusual”).
Overall, my impression is that the interannual variability here [directly related to ENSO] is much higher than it “felt” on the Atlantic coast.

Geo,
The ice extend is influenced by wind and ocean currents.
It is transported from the Arctic Ocean into the Atlantic.
(See icecap.us, last article left column)
In the mean time the NE passage is blocked. (see climatedepot.com and iceagenow.com
Simply forget the bla bla bla from the NSIDC.
They sing the AGW tune which is based on politics instead of science.
Prepare for another cold winter.

Dave The Engineer

The oceans are still holding heat from the last 10 to 15 years. There is a lot of water out there, a huge heat sink. And the currents carry the heat all over even into the Arctic. But once that heat is dissipated the cooling will accelerate. The poles are getting colder and the interior from the poles toward the equator getting cooler. Where do the glaciers start from? Not the oceans. An occasional hot day (or even a week) in the west and northwest? *That* is weather. The coldest July in memory? *That* is climate. Canadian wheat production is estimated to be down 20% this year. And next year? More fungus on the potato crop then seen in many years. Too cool and damp. Get ready folks. Mother nature is about to give us a chill we have not seen in 200 years. Weather is not the killer, hot or cold, it is man’s arrogance. Instead of being ready for it we’ll have cap and trade. Instead of drilling for oil or digging up coal we’ll have solar heaters for the many cloudy days with rain and snow in our future. I’m moving further south, so should you.

An Inquirer

_Jim (16:30:28) :
I would not be so dismissive of Julie’s comment. UHI (and siting issues) could be the deciding factor in the record temperature in Seattle, but the heat wave in southern Texas is amazing and historic. (Meanwhile, I am not alarmed because heat waves and dry weather is not unprecedented in Texas.)

David

Dave The Engineer (18:23:04) :
Uhh. No thanks. Alarmist, for sure, just not in the way we are used to.

Myron Mesecke

I’ve lived my entire life in Temple, TX. It has been extremely hot here in central Texas but due to the lack of rain the humidity has been very low. I have been able to tolerate this summer better than the years of normal heat but higher humidity. I finally got an inch of rain last Thursday and now the humidity is horrible.

An Inquirer (18:32:10) :
_Jim (16:30:28) :
I would not be so dismissive of Julie’s comment. UHI (and siting issues) could be the deciding factor …

No, this isn’t the case.
In the Austin and San Antonio area they *have* had drought conditions whereas we have not. As a matter of fact we had roughly three inches of rain over just the last three days, and I have not had to run the sprinklers/soaker hose for going on three weeks now on account of rain every several days. Prior to that we had *real* temps in the 100’s and I went through 2 cycles of watering (5 days or so between soaking the ground).
See, we have been receiving rain as a matter of the workings of several cold fronts that have progressed this far down (quite unusual for July here in North Central Texas), but by the time what remained of those ‘cold fronts’ upon reaching central Texas they got bupkis in the way of rain.
An Inquirer, I’m not just ‘readin the data’ I’m living the weather down here; no A/C in the car (3rd or 4th yr now) and down to one window A/C unit – believe me, I *feel* the changes in the weather down here more than most!

More weather is not climate….
Just south of Calgary Ab. I recorded a slightly above average july (.4C), yet the better part of July was below normal and then the heat hit in the last 2 weeks to save us. However, we are about to go cool again! And Yes, BC is smoke’n hot!
…and if its record highs its global warming….cool weather is only weather…..right….

Chris Reed

I have seen places like Austin and San Antonio in the post above, well I will add one for Houston. The Houston area had it driest and hottest May-July period on record. I was driving in the areas southwest of Houston last weekend and saw just about every crop that was planted was ruined. August and possibly September will continue the hot dry weather for much and south central and southeast Texas. The only hope I see is that an El Nino is on the way and every fall ( October in general) was cool and wet evey year with an El Nino coming on that year. The only expection was 2004. August 2004 was relatively cool here in the Houston area. I have look back to the early 90’s and every October since 1994 was very wet and cool in the Houston before and El Nino winter. Bring on the El Nino.
