After a stretch of unseasonably cool temperatures, it may be hard to believe how different the weather was just one year ago. 

OK - so it's June and before the second weekend of the month, the highest temperature, occurred on Friday, the 8th making it to 85°.  The average high temperature for the beginning of June is near 81°.  Three days have made it into the low 80s, but the rest of June has had highs only in the 70s!  Certainly an anomoly to a typical D.C. start to June when we usually start to feel more heat and humidity.  Speaking of humidity, dewpoints to start June have been in the upper 40s to low 50s -- almost unheard of, but very refreshing. 

D.C. had it's first 90 degree day of 2012 on Memorial Day, May 28th.  Last year, May 26th was the first 90 degree day, making it to 92°.  Unlike this year, it was a hot start to June!  In fact, the first heat wave (three consecutive days of 90 degree highs or higher) occurred May 30 (96°), 31 (98°), and June 1st (98°). 

The next stretch of 90 degree days, in 2011, was June 7th through the 12th.  The 8th and the 9th were both record setting days.  The chart below shows the six day heat wave and the high temperature departure. 

 

June 2011 Highs & High Departures

2012's start to June was much different. Take a look at the chart below and see the unbelievable difference in temperatures!  Now highs through the upcoming weekend (9th, 10th, and 11th will likely climb to near 90°), but still the first few days are a rarity for June. 

2012 June Highs & High Departures

June 5th was 10 degrees below average.  Highs this weekend will make to around 90 degrees, but no where near record breaking temperatures.  So if you're thinking it's hot this weekend, just remember this time last year was a lot hotter!
