The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 3, short of 90°F on every date, while 216 dates carry a normal low at or below freezing, the coldest 16°F near December 20.
The freezing stretch
The normal low stays at or below 32°F into May 11, then returns to freezing around October 9, covering 216 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is August 8, when 45% of years recorded at least a hundredth of an inch. The driest is June 10 at 9%. Summed across the calendar, that is about 84 wet dates a year.
The widest day
June 11 carries the biggest normal gap between afternoon and dawn, 43°F between the normal high and the normal low.

Where Fort Valley Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 216 nights a year, placing this among the most frost-prone tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 43°F, sharper than nine in ten ranked stations see.
Fort Valley earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Fort Valley spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 30%, with neither reaching the 35% that would mark a distinct wet season. Fort Valley has no dry season to plan around, though it does carry a 35.3°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 3.4" and June 0.2". The three wettest months together take 42% 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.
How Fort Valley's precipitation splits across the calendar
About 82 days a year record measurable precipitation here, carrying 20.6" between them, or roughly 0.25 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

What Fort Valley's climate means for you
Fort Valley runs 47°F a year - peaking in July, coldest in December.
- The frost-free window is short at about 106 days, opening only once the last spring freeze passes near June 11, which rules out long-season crops outdoors.
- Keeping warm is the dominant household load: 6,526 heating degree days against only 147 for cooling.

How Fort Valley's climate pattern fits together
heating led · moderate · mid swing
Fort Valley's energy balance leans toward cold weather: 6,526 annual heating degree days against 147 for cooling. Its 35.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 106 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and December mark the typical warm and cold ends of the calendar in Fort Valley's middle-range seasonal profile. The measured spread is 35.3°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Fort Valley's 20.6 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Fort Valley's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Fort Valley, not an official NOAA class or a year-ahead forecast.
The year in four calendar signals
- Warmest normal
- July
- Even at its warmest the station only averages 67°F (19°C), so no month here is hot by national standards.
- Coldest normal
- December
- The monthly mean of 31°F (0°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
- Rainfall rhythm
- August to June
- August is typically wettest; June is driest.
- Mild-temperature window
- June through September
- Monthly means sit between 55°F and 75°F in this window. Freezing days are still reported from January through December.
