The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 30, short of 90°F on every date, while 167 dates carry a normal low at or below freezing, the coldest 24°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 13, then returns to freezing around October 30, covering 167 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
August 27 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Easton Stands Nationally
The normal water year runs well above the national norm at roughly 50 inches.
Easton earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Easton's wet season runs through the cold months
December, January and February carry 43% of the year's precipitation here, while June through August contribute 7%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 33°F seasonal spread.
- Wettest month
- January, 8.1"

- Wettest three months

Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

Data-derived climate profile
How Easton's climate pattern fits together
heating led · wet · mid swing
Easton's energy balance leans toward cold weather: 7,310 annual heating degree days against 110 for cooling. Its 33.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Easton's frost-free season lasts about 150 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Easton's middle-range seasonal profile. The measured spread is 33.0°F. The annual average is 45°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Easton carries 49.8 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Easton's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Easton, not an official NOAA class or a year-ahead forecast.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 5319700), not an incorporated municipality. Match rule for Easton: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Easton comes from its primary NOAA station record.
