When the heat sits

Normal highs reach 90°F from June 13 through August 30, covering 79 dates. The broader mild season, normal highs of 70°F or more, runs March 10 to November 11.

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.

No freezing date

Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 34°F around January 10.

The widest day

April 12 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Data-derived climate profile

How Chatom's climate pattern fits together

mixed demand · mid swing

July and January mark the typical warm and cold ends of the calendar in Chatom's middle-range seasonal profile. The measured spread is 33.8°F. The annual average is 64°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Chatom's normal, at 2,306 and 2,100 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 227-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.

A moisture-range label is withheld because Chatom's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.

These labels group NOAA 1991-2020 normals from Chatom'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 Chatom, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Chatom's climate

How many days above 90°F does Chatom get?
Chatom averages about 88 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Chatom?
Chatom has 2,306 heating degree days and 2,100 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Chatom's primary station: CHATOM (USC00011566). For informational purposes only.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 0114008). Match rule for Chatom: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
