The year, day by day
The calendar barely moves in Guntersville: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 33°F near January 17 and 89°F near August 1.
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 33°F around January 17.
Where the wet dates fall
The likeliest wet date is February 19, when 43% of years recorded at least a hundredth of an inch. The driest is September 12 at 25%. Summed across the calendar, that is about 128 wet dates a year.
The widest day
April 6 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Guntersville Stands Nationally
This is one of the wettest normals climates ranked: about 57 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.
Guntersville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Guntersville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 29%, with neither reaching the 35% that would mark a distinct wet season. Guntersville has no dry season to plan around, though it does carry a 38.5°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 6.0" and October 3.5". The three wettest months together take 30% 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 Guntersville, it arrives in quantity
56.8" of precipitation falls across only about 128 wet days here, averaging 0.44 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 128 a year, 35% of all days
- Average depth per wet day
- 0.44 inches
- Most wet days
- December, about 13
- Fewest wet days
- October, about 8
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.
Snow reaches Guntersville, but rarely amounts to much
The normals record 0.7 inches of snow a year here, most likely in February. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 1 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Guntersville's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Guntersville averages 56.8 inches of precipitation a year. Annual snowfall totals 0.7 inches. 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 Guntersville's middle-range seasonal profile. The measured spread is 38.5°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Guntersville's normal, at 2,995 and 1,910 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 244 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 Guntersville'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 Guntersville, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
