Summer 2012 was hot, to be sure, but it was actually also the coolest in three years.

The meteorological summer, from June 1 through Aug. 31, was the 13th-hottest on record in Baltimore. The average temperature was 77.3 degrees at BWI Marshall Airport, about 2.5 degrees above the average summer temperature dating back to 1871.

The summer saw 40 days reach 90 degrees or hotter, well above the normal 26 days that hot in Baltimore. Six times, temperatures topped 100 degrees at BWI, including twice reaching 104 degrees.

In four of those cases, the heat tied or surpassed a record.

Despite that, the heat did not match that of the previous two summers.

In 2011, there were 37 days at or above 90 degrees, fewer than in 2012, but the average temperature was 77.8 degrees, good for No. 9 on the all-time list.

The year before that was record-setting. In 2010, there were 47 summer days at or above 90, and the average temperature of 79.3 degrees was the hottest on record. 

The heat of summer 2012 easily surpassed that of 2009, though, one of the coolest on record. That year, there were only 10 summer days at or above 90 degrees, and the average temperature was 74.2 degrees.
