Twenty-six of the 35 major climate sites wrapped up August on the wet side of normal, with 19 of them ranking this August among their 20 wettest on record. Back-to-back tropical systems in mid-August contributed to high rainfall totals in some areas.
On the other hand, several areas missed out on the heavy rain including much of northern New England, western New York, and Cape Cod, MA, with some of these locations seeing less than 75% of normal precipitation.

For September, NOAA’s Climate Prediction Center indicates an increased likelihood of above-normal precipitation for much of the Northeast, driven by rainfall from Tropical Depression Ida, which was moving into the region as this blog was published the morning of September 1. There’s a tilt toward above-normal temperatures for New England, eastern New York, and a sliver of New Jersey, with equal chances predicted for the rest of the Northeast.
