June 2010 Was Warmer, Much Wetter Than Average

OSWEGO, NY – It was just a tad warmer than normal last month – and a heck of a lot wetter than usual.

The average temperature last month was 66.7 degrees. That is 1.4 degrees above average.

“It was above average. I thought that we were going to be below average,” Bill Gregway, local observer for the National Weather Service, said of June’s average temperature.

The warmest June on record is 71.7 degrees in 2005. Right behind that is 71.2 degrees in 1949.

Storm clouds such as these hung over Central New York several days during June. Total rainfall last month was more than the three previous months' totals combined.
