The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 27, short of 90°F on every date, while 33 dates carry a normal low at or below freezing, the coldest 31°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into January 15, then returns to freezing around December 14, covering 33 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 November 27, when 64% of years recorded at least a hundredth of an inch. The driest is July 31 at 18%. Summed across the calendar, that is about 168 wet dates a year.
The widest day
August 9 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Clearbrook spreads its precipitation across the year
Neither half of the year dominates here: June through August take 11% of the annual total and December through February 34%, with neither reaching the 35% that would mark a distinct wet season. Clearbrook has no dry season to plan around, though it does carry an unusually narrow 26.1°F seasonal spread.
The gap between the wettest and driest month still matters: November averages 7.1" and July 1.4". The three wettest months together take 41% 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 Clearbrook's precipitation splits across the calendar
About 168 days a year record measurable precipitation here, carrying 49.8" between them, or roughly 0.30 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 Clearbrook, but rarely amounts to much
The normals record 10.8 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 6 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 Clearbrook's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Clearbrook, at 5,426 degree days versus 72 for cooling. Unlike a strongly continental record, however, its 26.1°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Clearbrook's frost-free season lasts about 183 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Clearbrook's 26.1°F seasonal spread is compact even though precipitation is abundant. July and December mark the typical warm and cold ends of the calendar. The annual average is 50°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Clearbrook carries 49.9 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 10.8 inches. 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 Clearbrook'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 Clearbrook, 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 Clearbrook's primary station: CLEARBROOK (USC00451484). 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 Clearbrook; 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 Clearbrook comes from its primary NOAA station record.
