When is the first frost expected to come to WMass?

WMass has had several frost advisories in the past weeks

CHICOPEE, Mass. (WWLP) – Despite the frost advisories, we’ve had no reports of frost so far in western Massachusetts.

Frost forms when moisture in the air freezes on cold surfaces like plants, grass and windshields. The earliest frost ever recorded in the lower Pioneer Valley was September 13th. Temperatures need to be in the lower 30s for frost to form and most of us haven’t dipped below the upper 30s.

Still, it’s made for some chilly nights this week. Larry Wood of East Longmeadow told 22News, “We did turn the heating on for one day. I think it was in the upper 30s one day and we turned the heat on for one night. I enjoy the change in the temperature and I like it.”

The lower Pioneer Valley usually doesn’t see its first frost until mid- October. Parts of Hampshire County and Franklin County can get frost in early October, and mid to late September for the Berkshires.

Our first freeze, when temperatures fall into the upper 20s, isn’t until late October in the lower Pioneer Valley, and early to mid-October for the rest of western Massachusetts.

The coldest we’ve been here in Chicopee this week was 38 degrees Wednesday morning and Monday morning, and we could see some more chilly mornings on the way.
