Climate Impacts - July 2000

Monthly Summary

July 2000 was the 2nd coolest July on record for the Northeast. The average temperature of 66.7 degrees was 2.9 degrees cooler than normal. The coolest July since comparable records began in 1895 was July 1962, with a monthly average temperature of 66.5 degrees. This was the coolest July on record in Delaware and Pennsylvania. It was the second coolest for the states of Maryland, New Jersey, New York and West Virginia. Departures around the region ranged from 1.6 degrees cooler than normal in Rhode Island to 4.0 degrees cooler than normal in Delaware. The number of days with temperatures above 90 degrees was much below normal this month. Most of the region did not see temperatures reach this mark at all during the month. New York City's Central Park, for example, did not record a single 90 degree day this July. The only other years this occurred were 1996, 1889, 1888, and 1875. (Records for Central Park date back to 1869.)

Precipitation for the month was slightly below normal in the Pennsylvania (90% of normal). The rest of the states in the region, however, received amounts in excess of normal. Connecticut displayed the greatest deviation from mean with 149% of the thirty-year average. Both Connecticut and New Jersey averaged more than 5 inches of rain this July, with 5.72 and 5.80 inches, respectively. The region overall reported 110% of normal. This was 1.22 inches more than last July and the wettest July since 1996.
