The year, day by day

Fort Smith Rgnl works both ends of the calendar. Normal highs climb to 95°F by July 29 and hold at or above 90°F on 79 dates, then normal lows drop to freezing or below on 55 dates, bottoming at 29°F around January 12.

When the heat sits

Normal highs reach 90°F from June 18 through September 4, covering 79 dates. The broader mild season, normal highs of 70°F or more, runs March 29 to October 30.

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 9, then returns to freezing around December 17, covering 55 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 9, when 35% of years recorded at least a hundredth of an inch. The driest is July 19 at 23%. Summed across the calendar, that is about 99 wet dates a year.

The widest day

April 6 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Fort Smith Rgnl Stands Nationally

Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 79 days a year, more than four out of five ranked stations record.

Fort Smith Rgnl spreads its precipitation across the year

Neither half of the year dominates here: June through August take 24% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Fort Smith Rgnl has no dry season to plan around, though it does carry a 42.7°F seasonal spread.

The gap between the wettest and driest month still matters: May averages 5.6" and February 2.7". The three wettest months together take 32% 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 Smith Rgnl, it arrives in quantity

47.3" of precipitation falls across only about 99 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.

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 Fort Smith Rgnl, but rarely amounts to much

The normals record 2.9 inches of snow a year here, most likely in January. 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 2 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 Fort Smith Rgnl's climate pattern fits together

mixed demand · wet · mid swing

Water is prominent even though neither heating nor cooling wholly defines the record. Fort Smith Rgnl averages 47.3 inches of precipitation a year. Annual snowfall totals 2.9 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 Fort Smith Rgnl's middle-range seasonal profile. The measured spread is 42.7°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 Fort Smith Rgnl's normal, at 3,098 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 226-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 Fort Smith Rgnl'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 Smith Rgnl, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Fort Smith Rgnl's climate

How much rain does Fort Smith Rgnl get?
Fort Smith Rgnl receives 47.3 inches of precipitation, including 2.9 inches of snow. Based on NOAA 30-year climate normals (1991-2020).

Fort Smith Rgnl averages about 78 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Fort Smith Rgnl?
Fort Smith Rgnl has 3,098 heating degree days and 2,177 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

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 Smith Rgnl; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
