The wettest areas saw more than 200% of normal and included parts of the Delmarva Peninsula, portions central and eastern Pennsylvania, multiple areas in New York, and a large portion of New England. Thirty-two of the region’s 35 major climate sites were wetter than normal, with Hartford, CT, and Albany, NY, seeing their wettest July on record. This July ranked among the 20 wettest Julys on record for another 17 major climate sites. Additionally, July 2023 ranked among the five all-time wettest months on record at Hartford and Albany, as well as Worcester, MA. The wet conditions allowed drought and abnormal dryness to contract across the region. However, a few drier areas such as central Maryland and eastern West Virginia saw drought persist.

The wet conditions of July may spill over into August according to NOAA’s Climate Prediction Center, which predicts an increased likelihood of above-normal precipitation for most of the Northeast. However, July’s heat may be missing in August as the outlook shows increased chances of below-normal temperatures for New England, much of New York, northeastern Pennsylvania, and northern New Jersey. Equal chances of below-, near-, or above-normal temperatures were forecast for the rest of the Northeast.
