The year, day by day
Sagemoor works both ends of the calendar. Normal highs climb to 92°F by July 27 and hold at or above 90°F on 32 dates, then normal lows drop to freezing or below on 141 dates, bottoming at 25°F around January 20.
When the heat sits
Normal highs reach 90°F from July 14 through August 14, covering 32 dates. The broader mild season, normal highs of 70°F or more, runs April 29 to October 8.
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 18, then returns to freezing around October 30, covering 141 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 18 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Sagemoor Stands Nationally
Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 36°F between the normal high and low.
Sagemoor earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Sagemoor's wet season runs through the cold months
December, January and February carry 36% of the year's precipitation here, while June through August contribute 13%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 39.4°F seasonal spread.
- Wettest month
- December, 1.4"
- Driest month
- July, 0.2"
- Wettest three months
- December, January, November (38% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

Scarce-water calendar
Where Sagemoor's limited precipitation lands
heating led · dry · mid swing
Sagemoor's energy balance leans toward cold weather: 5,351 annual heating degree days against 621 for cooling. Its 39.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Sagemoor's frost-free season lasts about 166 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 Sagemoor's middle-range seasonal profile. The measured spread is 39.4°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Sagemoor's cold-season load does not imply a wet climate. Annual precipitation is 9.8 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Sagemoor's primary station: SAGEMOOR (USC00457247). 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 Sagemoor; 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 Sagemoor comes from its primary NOAA station record.
