The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 10, short of 90°F on every date, while 28 dates carry a normal low at or below freezing, the coldest 31°F near January 17.
The freezing stretch
Freezing normal lows persist into February 2, covering 28 dates.
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 September 25, when 42% of years recorded at least a hundredth of an inch. The driest is November 7 at 30%. Summed across the calendar, that is about 131 wet dates a year.
The widest day
April 19 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Chapel Hill Williams spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Chapel Hill Williams has no dry season to plan around, though it does carry a 38°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 4.4" and February 2.8". 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 Chapel Hill Williams's precipitation splits across the calendar
About 131 days a year record measurable precipitation here, carrying 43.6" 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 Chapel Hill Williams's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in Chapel Hill Williams's middle-range seasonal profile. The measured spread is 38.0°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Chapel Hill Williams's normal, at 3,239 and 1,652 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 221-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
Chapel Hill Williams's 43.6 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 Chapel Hill Williams's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Chapel Hill Williams, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Chapel Hill Williams's primary station: CHAPEL HILL WILLIAMS AP (USW00093785). 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 Chapel Hill Williams; 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 Chapel Hill Williams comes from its primary NOAA station record.
