July 2013 is in the books as the warmest on record in Providence and Hartford. Not only it is the warmest July on record, it is also the warmest of any month on record. It was also a very warm month in Worcester and Boston, with both sites ending in the top-five warmest on record.
The records were smashed in Providence and Hartford with both areas finishing nearly a degree warmer than the previous record. While two long stretches of hot, humid weather helped set the record, the biggest contributor may have been the consistently warm nighttime temperatures. Only four days out of the month saw a cooler than normal low temperature in Providence, and the temperature did not fall below 60° all month. The average low temperature for the month was 70.4°, well above the normal average low of 64.4°. The average high temperature was 86.4°, compared to a normal average high of 82.8°. Overall, the average daily temperature was 4.9° warmer than normal.
The hottest month on record in Providence and Hartford did not feature a single record high maximum temperature. In fact, the only record high temperature set all month at the four main climate stations in Southern New England was on Friday, July 19 when Boston reached 99°, breaking the old record of 98° set in 1982.
