The year, day by day
Richland works both ends of the calendar. Normal highs climb to 94°F by July 26 and hold at or above 90°F on 39 dates, then normal lows drop to freezing or below on 183 dates, bottoming at 21°F around December 21.
When the heat sits
Normal highs reach 90°F from July 9 through August 16, covering 39 dates. The broader mild season, normal highs of 70°F or more, runs May 9 to October 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 April 15, then returns to freezing around October 16, covering 183 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.
The widest day
August 2 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Richland Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 183 nights a year, more than most ranked stations.
Richland earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Data-derived climate profile
How Richland's climate pattern fits together
heating led · mid swing
Richland's energy balance leans toward cold weather: 6,231 annual heating degree days against 597 for cooling. Its 43.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 144 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 January mark the typical warm and cold ends of the calendar in Richland's middle-range seasonal profile. The measured spread is 43.5°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Richland's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Richland'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 Richland, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Richland's primary station: RICHLAND (USC00357160). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 4161700). Match rule for Richland: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Richland comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
