The year, day by day
The year in Huntsville runs from a mild 39°F around January 7 to 94°F at the peak near August 1, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 22 through September 2, covering 73 dates. The broader mild season, normal highs of 70°F or more, runs March 20 to November 8.
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 39°F around January 7.
Where the wet dates fall
The likeliest wet date is February 9, when 31% of years recorded at least a hundredth of an inch. The driest is August 3 at 20%. Summed across the calendar, that is about 93 wet dates a year.
The widest day
April 10 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Where Huntsville Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 21°F.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 73 days a year, more than four out of five ranked stations record.
Huntsville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Huntsville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Huntsville has no dry season to plan around, though it does carry a 33.7°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 5.5" and July 3.1". The three wettest months together take 29% 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.
When it rains in Huntsville, it arrives in quantity
51.3" of precipitation falls across only about 93 wet days here, averaging 0.55 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 93 a year, 26% of all days
- Average depth per wet day
- 0.55 inches
- Most wet days
- January, about 9
- Fewest wet days
- October, about 7
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Huntsville's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Huntsville's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Huntsville averages 51.3 inches of precipitation a year. Recorded annual snowfall is negligible. The monthly table supplies the seasonal distribution hidden by that annual total.
August and January mark the typical warm and cold ends of the calendar in Huntsville's middle-range seasonal profile. The measured spread is 33.7°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Huntsville's normal, at 1,941 and 2,516 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.
The frost-free window extends for about 272 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
These labels group NOAA 1991-2020 normals from Huntsville'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 Huntsville, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
