May 2013, thanks to the 90 degree days that closed out the month, finishes as a slightly above average month on temperatures. We notched in at 64.8 degrees for the final temperature in Philadelphia, nine tenths of a degree above average. It was a fair amount cooler than last May, which averaged out to 68.2 degrees for the month. The balance of the region was above average by a degree or so, with Atlantic City coming in squarely at average.
Rainfall ended up below average by an inch and a third locally, with us now running a rainfall deficit of just over four inches year-to-date.
