The year, day by day
The year in Vacaville Nut Tree runs from a mild 37°F around December 23 to 95°F at the peak near July 13, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 17 through September 19, covering 95 dates. The broader mild season, normal highs of 70°F or more, runs April 4 to November 7.
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 37°F around December 23.
Where the wet dates fall
The likeliest wet date is January 9, when 34% of years recorded at least a hundredth of an inch. The driest is July 16 at 0%. Summed across the calendar, that is about 61 wet dates a year.
The widest day
July 13 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Vacaville Nut Tree Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 95 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 36°F, sharper than nine in ten ranked stations see.
Vacaville Nut Tree earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Vacaville Nut Tree's wet season runs through the cold months
December, January and February carry 62% 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 29.5°F seasonal spread.
- Wettest month
- January, 5.3"
- Driest month
- July, 0.0"
- Wettest three months
- January, December, February (62% 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 Vacaville Nut Tree, it arrives in quantity
24.8" of precipitation falls across only about 61 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.

- about 61 a year, 17% 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 Vacaville Nut Tree's climate pattern fits together
mixed demand · moderate · low swing
Temperature varies within a narrow 29.5°F band across the normal year. July and December mark the typical warm and cold ends of the calendar. The annual average is 62°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Vacaville Nut Tree combines a compact 29.5°F annual temperature range with meaningful demand on both sides of the thermostat: 2,446 heating and 1,391 cooling degree days. The balance matters more here than either annual total in isolation.
The frost-free window extends for about 283 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.
Vacaville Nut Tree's 24.8 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 Vacaville Nut Tree's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Vacaville Nut Tree, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Vacaville Nut Tree's primary station: VACAVILLE NUT TREE AP (USW00093241). 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 Vacaville Nut Tree; 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 Vacaville Nut Tree comes from its primary NOAA station record.
