The year, day by day
Dewey works both ends of the calendar. Normal highs climb to 101°F by July 18 and hold at or above 90°F on 106 dates, then normal lows drop to freezing or below on 158 dates, bottoming at 15°F around January 6.
When the heat sits
Normal highs reach 90°F from June 2 through September 15, covering 106 dates. The broader mild season, normal highs of 70°F or more, runs April 4 to October 23.
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 March 26, then returns to freezing around October 21, covering 158 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
June 20 carries the biggest normal gap between afternoon and dawn, 43°F between the normal high and the normal low.

Where Dewey Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 106 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
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.
Dewey earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Data-derived climate profile
How Dewey's climate pattern fits together
heating led · mid swing
Dewey's energy balance leans toward cold weather: 4,991 annual heating degree days against 1,392 for cooling. Its 51.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Dewey's frost-free season lasts about 165 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Dewey's middle-range seasonal profile. The measured spread is 51.4°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Dewey'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 Dewey'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 Dewey, 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 Dewey's primary station: DEWEY (USC00422150). 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 Dewey; 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 Dewey 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.
