The year, day by day
Chesterfield works both ends of the calendar. Normal highs climb to 93°F by July 12 and hold at or above 90°F on 66 dates, then normal lows drop to freezing or below on 23 dates, bottoming at 31°F around January 15.
When the heat sits
Normal highs reach 90°F from June 18 through August 22, covering 66 dates. The broader mild season, normal highs of 70°F or more, runs March 26 to November 3.
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
Freezing normal lows persist into January 27, covering 23 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.
The widest day
April 4 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Where Chesterfield Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 66 days a year, more than four out of five ranked stations record.
The normal water year runs well above the national norm at roughly 50 inches.
Chesterfield earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Chesterfield spreads its precipitation across the year
Neither half of the year dominates here: June through August take 32% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Chesterfield has no dry season to plan around, though it does carry a 37.1°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 5.7" and February 3.1". The three wettest months together take 32% 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 Chesterfield's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Chesterfield averages 49.8 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 Chesterfield's middle-range seasonal profile. The measured spread is 37.1°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Chesterfield's normal, at 2,789 and 1,990 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 216-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 Chesterfield'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 Chesterfield, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
