Frost, heat & the growing season

About 141 frost-free days a year

In half of years the last 32° night comes by May 11 and the first by October 1. Frost and day counts come from NOAA’s station at Harmony, ME, 8 miles from the town’s center, at about the same height.

Short record. NOAA estimated Harmony, ME’s counts from 9 years of data and its neighbors’, not a full 30-year record.

Heating & cooling

Heating and cooling a home in Cambridge

96% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through May.

8,160 heating degree daysMore heating than 97% of U.S. towns
316 cooling degree daysLess cooling than 94% of U.S. towns

Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Harmony, ME.

Warmer than it used to be

The last 30 years in Cambridge averaged 1.6° warmer than the 1900s. The biggest change is in December (+4.2°).
