The year, day by day
Methow works both ends of the calendar. Normal highs climb to 91°F by July 28 and hold at or above 90°F on 23 dates, then normal lows drop to freezing or below on 133 dates, bottoming at 21°F around January 1.
When the heat sits
Normal highs reach 90°F from July 19 through August 10, covering 23 dates. The broader mild season, normal highs of 70°F or more, runs May 5 to October 3.
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 17, then returns to freezing around November 6, covering 133 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
July 26 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Data-derived climate profile
How Methow's climate pattern fits together
heating led · mid swing
Methow's energy balance leans toward cold weather: 6,082 annual heating degree days against 660 for cooling. Its 45.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Methow's frost-free season lasts about 177 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Methow's middle-range seasonal profile. The measured spread is 45.5°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 Methow'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 Methow'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 Methow, 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 Methow's primary station: METHOW 2 S (USC00455326). 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 a census-designated place (GEOID 5345355), not an incorporated municipality. Match rule for Methow: 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 Methow 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.
