It was a hot summer! July 2012 was the hottest month ever recorded since U.S. weather records began in 1895. This July was also the second hottest month in D.C. Reagan National, as of September 5th, has had 52 days with highs 90° or higher.
- 90 Degree Days, So Far, In 2012
So, now we're into September - the start of meteorological autumn. Now, if you're like me, you sometimes forget that with the flip of the calendar month, the temperature doesn't magically drop for it to instantly feel like fall. I got the memo when I stepped outside on the first day of September and realized it was 95°!
The average high in the beginning of September is 84° in D.C. By the end of the month, the average high is 74°. Even though the 95° high Reagan National reached on September 1st is about 10 degrees warmer than average, it's not anything unusual. Take a look back at the past 10 years.
The latest we've had a high over 90° in September was back in 2010. September 25th got to 93° - boy do I hope the 90s don't last through the end of September! Can you tell I'm ready for fall? Five out of the last ten years have had 90° highs in September. On the flip side, look at 2010! September 2010 had no 90° days and the last 90 degree day that year was on August 4th!
The 2012 90 degree day counter continues. I think we're in for at least two more to round out the work week.
