The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 24, short of 90°F on every date, while 196 dates carry a normal low at or below freezing, the coldest 8°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 22, then returns to freezing around October 10, covering 196 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
September 3 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Fairfield Ranger Station Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 196 nights a year, more than most ranked stations.
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.
Fairfield Ranger Station earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Fairfield Ranger Station's wet season runs through the cold months
December, January and February carry 38% of the year's precipitation here, while June through August contribute 11%. 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 wide 48.7°F gap between its warmest and coldest month.

- January, 2.1"

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 Fairfield Ranger Station's limited precipitation lands
heating led · dry · mid swing
Fairfield Ranger Station's energy balance leans toward cold weather: 8,520 annual heating degree days against 216 for cooling. Its 48.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 98 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 Fairfield Ranger Station's middle-range seasonal profile. The measured spread is 48.7°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Fairfield Ranger Station's cold-season load does not imply a wet climate. Annual precipitation is 14.6 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 Fairfield Ranger Station's primary station: FAIRFIELD RS (USC00103108). 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 Fairfield Ranger Station; 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 Fairfield Ranger Station comes from its primary NOAA station record.
