The year, day by day
The year in Birmingham runs from a mild 35°F around January 15 to 91°F at the peak near July 27, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 29 through August 25, covering 58 dates. The broader mild season, normal highs of 70°F or more, runs March 27 to October 31.
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 35°F around January 15.
Where the wet dates fall
The likeliest wet date is July 15, when 38% of years recorded at least a hundredth of an inch. The driest is September 30 at 23%. Summed across the calendar, that is about 119 wet dates a year.
The widest day
April 4 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Birmingham 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.

Birmingham spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Birmingham has no dry season to plan around, though it does carry a 36.8°F seasonal spread.
The gap between the wettest and driest month still matters: March averages 5.7" and October 3.3". 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 Birmingham, it arrives in quantity
56.6" of precipitation falls across only about 118 wet days here, averaging 0.48 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 118 a year, 32% of all days
- Average depth per wet day
- 0.48 inches
- Most wet days
- July, about 12
- Fewest wet days
- September, 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.
Snow reaches Birmingham, but rarely amounts to much
The normals record 1.4 inches of snow a year here, most likely in March. 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 Birmingham's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Birmingham averages 56.6 inches of precipitation a year. Annual snowfall totals 1.4 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 Birmingham's middle-range seasonal profile. The measured spread is 36.8°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 Birmingham's normal, at 2,533 and 2,177 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 235-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 Birmingham'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 Birmingham, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
