The year, day by day
The year in Savannah runs from a mild 40°F around January 12 to 93°F at the peak near July 14, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 18 through August 24, covering 68 dates. The broader mild season, normal highs of 70°F or more, runs March 9 to November 15.
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 40°F around January 12.
Where the wet dates fall
The likeliest wet date is July 31, when 42% of years recorded at least a hundredth of an inch. The driest is October 30 at 21%. Summed across the calendar, that is about 108 wet dates a year.
The widest day
April 10 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Savannah Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 68 days a year, more than four out of five ranked stations record.
Savannah earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Savannah runs a summer-peaked wet season
37% of Savannah's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 6.7", on a 32.3°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, July, August, taking 37% of the annual total between them.
- Driest month: November at 2.4".
- Winter share: 19% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Savannah, it arrives in quantity
48.1" of precipitation falls across only about 108 wet days here, averaging 0.45 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 108 a year, 29% of all days
- Average depth per wet day
- 0.45 inches
- Most wet days
- August, about 13
- Fewest wet days
- April, 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.
Savannah'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 Savannah's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Savannah averages 48.1 inches of precipitation a year. Recorded annual snowfall is negligible. 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 Savannah's middle-range seasonal profile. The measured spread is 32.3°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 Savannah's normal, at 1,675 and 2,596 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 273 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 Savannah'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 Savannah, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
