Summer 2013 weather was about average -- or was it?

Meteorological summer ended Saturday, and it proved right about average for both temperatures and rainfall. But that doesn't tell the whole story.

Temperatures averaged 75.7 degrees from June through August, just shy of one degree warmer than the average dating back to 1871. That made it the 61st warmest summer on record out of the 142 on record.

But much of the summer felt cooler than normal, given that it was the coolest summer since 2009 and the first since then without a single 100-degree day recorded for Baltimore. The past three summers averaged between 77 and 80 degrees. This summer wasn't quite as cool as summer 2009, which averaged cooler than 75 degrees.

It's all relative.

Rainfall was meanwhile nearly an inch above normal, with 11.7 inches for the summer. It was, however, the driest summer since 2010, when just shy of 11 inches fell.

Still, this summer's total suggests it was a pretty wet summer, when the fact is, the summer included an extraordinarily wet June and unusually dry months of July and August.

June was the eighth-wettest on record and second wettest since Hurricane Agnes soaked Baltimore in June 1972. August was meanwhile the tenth-driest on record, with 1.13 inches of rain.

So, moving toward fall, we are actually behind on rain despite the summer's total. Baltimore rainfall had been running ahead of normal by as much as 2-3 inches in June and July, but now lags the norm by several inches.
