Hottest July? Well Not Everywhere

Record Heat but not Worldwide

OK so I just came back from a break from the typical DC summer heat and humidity.  This July sure was hot and in the headlines "Second Hottest in DC Weather Records".  Look at this and in Eileen's blog about the July heat. 



Statewide it was the warmest July on record for Virginia, the second hottest July on record in DC (100+ years of records) and Maryland and in many places east of the Rockies, one of the hottest and driest months in weather records.  For the U.S. overall, it was the hottest month in weather records.  But look at this global overview from the National Climatic Data Center.  It's the middle of winter in the Southern Hemisphere and the coolest July in Australia in many years. 


 As you can see (larger image here) England and the UK had the coolest July in more than 10 years.  Still a bit chilly during the Olympics.  And in Scandinavia and the Baltic, where I spent part of my vacation, rather cloudy and cool.  Many folks grumbling about how cloudy and cool the summer had been.  The latest global 30 day temperature anomaly compiled by NOAA shows the general July trend continuing.

Sure in this global temperature anomaly (departure form long-term average) the continuing mid-summer heat in not only the U.S. but much of North America clearly shows, but parts of Australia are almost 7º colder than average and Scandinavia and the Baltic the last month have been relatively chilly . . . certainly compared to St. Louis and Washington, DC.  Want cold?  Head to mid-winter in Antarctic where it was -101º during the last 3 days at the Amundsen-Scott Station at the South Pole,

Yes, in most of the world July 2012, and as you can see the last 30 days, have been toasty. . .and sure toasty where most people live.  Ready for some cool weather?  These patterns do change, although the high latitude warmth seems more and more, another signal that climate models are correct about long term global warming.  But there is always this Autumn and Winter.  Alex's blog is neat about the joys of the changing seasons.  More hot summers ahead?  Another next year would make the 4 hottest in DC in a row.  I'll stick my probabilistic neck out and say not likely.  And not likely the United Kingdom will be as chilly next summer either . . .although the Brits grumble about the weather even more than we do.  First freeze can't be too far away.
