The year, day by day
Fort Griffin works both ends of the calendar. Normal highs climb to 98°F by July 31 and hold at or above 90°F on 99 dates, then normal lows drop to freezing or below on 65 dates, bottoming at 26°F around January 6.
When the heat sits
Normal highs reach 90°F from June 2 through September 8, covering 99 dates. The broader mild season, normal highs of 70°F or more, runs March 21 to November 6.
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.
The freezing stretch
The normal low stays at or below 32°F into February 12, then returns to freezing around December 10, covering 65 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 May 24, when 24% of years recorded at least a hundredth of an inch. The driest is January 12 at 10%. Summed across the calendar, that is about 54 wet dates a year.
The widest day
March 29 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Fort Griffin Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 99 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Fort Griffin earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Fort Griffin spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 15%, with neither reaching the 35% that would mark a distinct wet season. Fort Griffin has no dry season to plan around, though it does carry a 40.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 3.8" and January 1.2". The three wettest months together take 36% 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 Fort Griffin, it arrives in quantity
27.9" of precipitation falls across only about 54 wet days here, averaging 0.51 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

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.

Data-derived climate profile
How Fort Griffin's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in Fort Griffin's middle-range seasonal profile. The measured spread is 40.8°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Fort Griffin's normal, at 2,917 and 2,276 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 223-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.
Fort Griffin's 27.9 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 Griffin'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 Fort Griffin, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Fort Griffin's primary station: FT GRIFFIN (USC00413265). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Fort Griffin; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Fort Griffin comes from its primary NOAA station record.
