Regional context

In Huntsville, NOAA NCEI 1991-2020 normals put January near 43°F and July near 81°F — a 39°F seasonal arc — with about 54.3 inches of precipitation over 79 rainy or snowy days.

No season owns Huntsville's rain: December reaches 5.9 inches across 7.3 days and September keeps 3.5 inches on 4.4, an even spread through Huntsville's year. That lines Huntsville up with places like Redstone Arsenal, AL, Madison, AL and Triana, AL, fed by overlapping storm tracks.

Huntsville reaches its last hard frost near mid-March; that is the cue for peas, lettuce, spinach, and radishes. Huntsville's heat-lovers — tomatoes, peppers, squash — hold off until Huntsville's frost risk clears, 10-14 days on. The season ends by mid-December in Huntsville, once hard frosts set back in. Huntsville's low ground holds frost later into spring than Huntsville's benches, which run 3-5 days ahead.
