The year, day by day
The year in Campo runs from a mild 33°F around December 15 to 93°F at the peak near August 15, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 3 through September 9, covering 69 dates. The broader mild season, normal highs of 70°F or more, runs April 20 to November 12.
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 33°F around December 15.
Where the wet dates fall
The likeliest wet date is February 22, when 29% of years recorded at least a hundredth of an inch. The driest is June 11 at 2%. Summed across the calendar, that is about 46 wet dates a year.
The widest day
June 24 carries the biggest normal gap between afternoon and dawn, 40°F between the normal high and the normal low.

Where Campo Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 40°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 69 days a year, more than four out of five ranked stations record.
Campo earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Campo's wet season runs through the cold months
December, January and February carry 60% of the year's precipitation here, while June through August contribute 3%. 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 26.6°F seasonal spread.
- Wettest month
- February, 2.8"
- Driest month
- June, 0.1"
- Wettest three months
- February, January, December (60% 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 Campo's precipitation splits across the calendar
About 47 days a year record measurable precipitation here, carrying 12.6" between them, or roughly 0.27 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.

Scarce-water calendar
Where Campo's limited precipitation lands
heating led · dry · low swing
Heating is the larger measured load in Campo, at 3,216 degree days versus 818 for cooling. Unlike a strongly continental record, however, its 26.6°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Campo's frost-free season lasts about 186 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 26.6°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 58°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Campo's cold-season load does not imply a wet climate. Annual precipitation is 12.6 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 source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Campo's primary station: CAMPO ASOS (USW00003164). 2 NOAA stations are mapped to the Campo area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 0610508), not an incorporated municipality. Match rule for Campo: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
