The year, day by day
Chatham Wtp works both ends of the calendar. Normal highs climb to 90°F by July 13 and hold at or above 90°F on 22 dates, then normal lows drop to freezing or below on 71 dates, bottoming at 30°F around January 25.
When the heat sits
Normal highs reach 90°F from July 6 through July 27, covering 22 dates. The broader mild season, normal highs of 70°F or more, runs April 6 to October 23.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into February 22, then returns to freezing around December 14, covering 71 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.
The widest day
April 10 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Chatham Wtp Stands Nationally
The normal water year runs well above the national norm at roughly 50 inches.
Chatham Wtp earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Chatham Wtp spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Chatham Wtp has no dry season to plan around, though it does carry a 39.7°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 5.2" and February 3.1". The three wettest months together take 31% 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.

Data-derived climate profile
How Chatham Wtp's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Chatham Wtp averages 49.9 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Chatham Wtp's middle-range seasonal profile. The measured spread is 39.7°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Chatham Wtp's normal, at 3,351 and 1,703 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 220-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.
These labels group NOAA 1991-2020 normals from Chatham Wtp'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 Chatham Wtp, 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 Chatham Wtp's primary station: CHATHAM WTP (USC00311700). 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 Chatham Wtp; 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 Chatham Wtp comes from its primary NOAA station record.
