The year, day by day
The year in Lake Solano runs from a mild 37°F around January 1 to 98°F at the peak near July 21, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 14 through September 21, covering 100 dates. The broader mild season, normal highs of 70°F or more, runs April 2 to November 6.
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 January 1.
The widest day
August 1 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Lake Solano Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 100 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 39°F, sharper than nine in ten ranked stations see.
Lake Solano earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Data-derived climate profile
How Lake Solano's climate pattern fits together
mixed demand · mid swing
July and January mark the typical warm and cold ends of the calendar in Lake Solano's middle-range seasonal profile. The measured spread is 30.9°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Lake Solano's normal, at 2,357 and 1,596 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
The frost-free window extends for about 304 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.
A moisture-range label is withheld because Lake Solano's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Lake Solano'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 Lake Solano, 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 Lake Solano's primary station: LAKE SOLANO (USC00044712). 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 Lake Solano; 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 Lake Solano comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
