The last three summer seasons have ranked as the three warmest summers since records began, with 2010 being the warmest, 2011 the second warmest and this year the third warmest on record.

The statewide June through August precipitation average of 9.72” was more than three inches below the 1895-2012 average, making 2012 the 29th driest summer season since 1895 (Figure 2).

Although the final data may change the rankings slightly, it is clear that summer 2012 was unusually warm and dry across the First State.
