The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 6, short of 90°F on every date, while 95 dates carry a normal low at or below freezing, the coldest 26°F near January 17.
The freezing stretch
The normal low stays at or below 32°F into February 28, then returns to freezing around November 26, covering 95 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 February 23, when 44% of years recorded at least a hundredth of an inch. The driest is September 29 at 27%. Summed across the calendar, that is about 139 wet dates a year.
The widest day
October 27 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Bristol Tri City 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 26%, with neither reaching the 35% that would mark a distinct wet season. Bristol Tri City has no dry season to plan around, though it does carry a 39.2°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 5.0" and October 2.5". The three wettest months together take 29% 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 Bristol Tri City's precipitation splits across the calendar
About 138 days a year record measurable precipitation here, carrying 44.0" between them, or roughly 0.32 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.
Snow reaches Bristol Tri City, but rarely amounts to much
The normals record 9.2 inches of snow a year here, most likely in January. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 9 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Bristol Tri City's climate pattern fits together
heating led · moderate · mid swing
Bristol Tri City's energy balance leans toward cold weather: 4,150 annual heating degree days against 1,105 for cooling. Its 39.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Bristol Tri City's frost-free season lasts about 191 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 Bristol Tri City's middle-range seasonal profile. The measured spread is 39.2°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Bristol Tri City's 44.0 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 9.2 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Bristol Tri City'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 Bristol Tri City, 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 Bristol Tri City's primary station: BRISTOL TRI CITY AP (USW00013877). 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 Bristol Tri City; 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 Bristol Tri City comes from its primary NOAA station record.
