The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 14, short of 90°F on every date, while 122 dates carry a normal low at or below freezing, the coldest 20°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into March 24, then returns to freezing around November 24, covering 122 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 16, when 41% of years recorded at least a hundredth of an inch. The driest is August 30 at 31%. Summed across the calendar, that is about 129 wet dates a year.
The widest day
May 2 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Hartford Brainard Fld 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. Hartford Brainard Fld has no dry season to plan around, though it does carry a wide 46.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 4.2" and February 2.6". 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.
How Hartford Brainard Fld's precipitation splits across the calendar
About 129 days a year record measurable precipitation here, carrying 42.8" between them, or roughly 0.33 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Hartford Brainard Fld's climate pattern fits together
heating led · moderate · mid swing
Hartford Brainard Fld's energy balance leans toward cold weather: 5,620 annual heating degree days against 914 for cooling. Its 46.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Hartford Brainard Fld's frost-free season lasts about 192 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 Hartford Brainard Fld's middle-range seasonal profile. The measured spread is 46.6°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Hartford Brainard Fld's 42.8 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Hartford Brainard Fld'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 Hartford Brainard Fld, not an official NOAA class or a year-ahead forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Hartford Brainard Fld's primary station: HARTFORD BRAINARD FLD (USW00014752). 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 Hartford Brainard Fld; 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 Hartford Brainard Fld comes from its primary NOAA station record.
