The year, day by day
Summer here tops out rather than builds: the warmest normal high is 80°F around July 15, short of 90°F on every date, while 162 dates carry a normal low at or below freezing, the coldest 11°F near January 25.
The freezing stretch
The normal low stays at or below 32°F into April 14, then returns to freezing around November 5, covering 162 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.
Where the wet dates fall
The likeliest wet date is May 15, when 42% of years recorded at least a hundredth of an inch. The driest is August 31 at 30%. Summed across the calendar, that is about 131 wet dates a year.
The widest day
April 30 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Ashburnham N Stands Nationally
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Ashburnham N earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Ashburnham N spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Ashburnham N has no dry season to plan around, though it does carry a wide 47.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 5.1" and January 3.2". The three wettest months together take 28% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Ashburnham N, it arrives in quantity
48.7" of precipitation falls across only about 131 wet days here, averaging 0.37 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 131 a year, 36% of all days
- Average depth per wet day
- 0.37 inches
- Most wet days
- May, about 13
- Fewest wet days

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Ashburnham N's climate pattern fits together
heating led · wet · mid swing
Ashburnham N's energy balance leans toward cold weather: 7,462 annual heating degree days against 348 for cooling. Its 47.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Ashburnham N's frost-free season lasts about 155 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 Ashburnham N's middle-range seasonal profile. The measured spread is 47.6°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, Ashburnham N carries 48.7 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 Ashburnham N'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 Ashburnham N, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Ashburnham N's primary station: ASHBURNHAM N (USC00190192). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Ashburnham N; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Ashburnham N comes from its primary NOAA station record.
