The year, day by day
Summer here tops out rather than builds: the warmest normal high is 79°F around July 15, short of 90°F on every date, while 155 dates carry a normal low at or below freezing, the coldest 15°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around November 8, covering 155 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 December 17, when 54% of years recorded at least a hundredth of an inch. The driest is August 24 at 36%. Summed across the calendar, that is about 168 wet dates a year.
The widest day
May 14 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Bradford spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Bradford has no dry season to plan around, though it does carry a 43.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 4.2" and February 2.1". The three wettest months together take 30% 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 Bradford's precipitation splits across the calendar
About 167 days a year record measurable precipitation here, carrying 41.9" between them, or roughly 0.25 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 Bradford's climate pattern fits together
heating led · moderate · mid swing
Bradford's energy balance leans toward cold weather: 7,224 annual heating degree days against 282 for cooling. Its 43.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 136 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Bradford's middle-range seasonal profile. The measured spread is 43.8°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Bradford's 41.9 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 Bradford'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 Bradford, not an official NOAA class or a year-ahead forecast.
