The year, day by day
The year in Ukiah Muni runs from a mild 36°F around December 17 to 95°F at the peak near July 23, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 29 through September 11, covering 75 dates. The broader mild season, normal highs of 70°F or more, runs April 21 to November 4.
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.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 36°F around December 17.
Where the wet dates fall
The likeliest wet date is December 21, when 49% of years recorded at least a hundredth of an inch. The driest is August 10 at 1%. Summed across the calendar, that is about 86 wet dates a year.
The widest day
July 30 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Ukiah Muni 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.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 75 days a year, more than four out of five ranked stations record.
Ukiah Muni earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Ukiah Muni's wet season runs through the cold months
December, January and February carry 57% of the year's precipitation here, while June through August contribute 1%. 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 an unusually narrow 28.7°F seasonal spread.
- Wettest month
- December, 6.9"
- Driest month
- July, 0.0"
- Wettest three months
- December, January, February (57% 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.
When it rains in Ukiah Muni, it arrives in quantity
34.8" of precipitation falls across only about 86 wet days here, averaging 0.41 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 86 a year, 23% of all days
- Average depth per wet day

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Ukiah Muni's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Ukiah Muni, at 2,879 degree days versus 1,005 for cooling. Unlike a strongly continental record, however, its 28.7°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
The frost-free window extends for about 261 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Temperature varies within a narrow 28.7°F band across the normal year. July and December mark the typical warm and cold ends of the calendar. The annual average is 60°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Ukiah Muni's 34.8 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Ukiah Muni'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 Ukiah Muni, not an official NOAA class or a year-ahead forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Ukiah Muni's primary station: UKIAH MUNI AP (USW00023275). 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 Ukiah Muni; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
