What is each month like in Chicopee?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

How much snow, how late a frost, what zone and how much sun in Chicopee?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Westfield (8 miles W, 271 ft). NOAA publishes no snowfall normal for it; the nearest record that has one, Belchertown (13 miles NE), gets 48 inches a year. The last spring frost (32°F) comes after May 3 in half of years and the first autumn frost before October 8. Its record high is 103°F (2010) and its record low −20°F (1934), on the National Weather Service's long record for the area (kept since 1926).
The USDA's 2023 Plant Hardiness Zone Map puts Chicopee in zone 6a across its 3 ZIP code areas.
Over a year 71% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (3.8 kWh per square metre a day, NASA POWER 2001-2020); August is the sunniest month (77%) and December the cloudiest (62%).
Westfield's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for Chicopee; the nearest record's month pages have them.
