The year, day by day
The year in Sacramento Metro runs from a mild 37°F around December 16 to 94°F at the peak near July 15, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 21 through September 9, covering 81 dates. The broader mild season, normal highs of 70°F or more, runs April 9 to November 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.
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 16.
Where the wet dates fall
The likeliest wet date is January 7, when 39% of years recorded at least a hundredth of an inch. The driest is July 17 at 0%. Summed across the calendar, that is about 70 wet dates a year.
The widest day
July 10 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Sacramento Metro Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 81 days a year, more than four out of five ranked stations record.
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.
Sacramento Metro earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Sacramento Metro's wet season runs through the cold months
December, January and February carry 58% of the year's precipitation here, while June through August contribute 2%. 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 30.2°F seasonal spread.
- Wettest month
- January, 3.7"
- Driest month
- July, 0.0"
- Wettest three months
- January, February, December (58% 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.
How Sacramento Metro's precipitation splits across the calendar
About 70 days a year record measurable precipitation here, carrying 18.0" between them, or roughly 0.26 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Sacramento Metro's climate pattern fits together
heating led · dry · mid swing
Sacramento Metro's energy balance leans toward cold weather: 2,644 annual heating degree days against 1,279 for cooling. Its 30.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Sacramento Metro has a long frost-free window of roughly 275 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
July and December mark the typical warm and cold ends of the calendar in Sacramento Metro's middle-range seasonal profile. The measured spread is 30.2°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Sacramento Metro's cold-season load does not imply a wet climate. Annual precipitation is 18.0 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.
These labels group NOAA 1991-2020 normals from Sacramento Metro'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 Sacramento Metro, 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 Sacramento Metro's primary station: SACRAMENTO METRO AP (USW00093225). 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 Sacramento Metro; 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 Sacramento Metro comes from its primary NOAA station record.
