The year, day by day
The year in Northridge Cal State runs from a mild 45°F around December 14 to 93°F at the peak near August 24, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 11 through September 13, covering 65 dates. The broader mild season, normal highs of 70°F or more, runs March 6 to November 27.
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 45°F around December 14.
Where the wet dates fall
The likeliest wet date is February 19, when 25% of years recorded at least a hundredth of an inch. The driest is August 9 at 1%. Summed across the calendar, that is about 36 wet dates a year.
The widest day
August 24 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Where Northridge Cal State Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 65 days a year, more than four out of five ranked stations record.
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.

Northridge Cal State's wet season runs through the cold months
December, January and February carry 66% 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 21.8°F seasonal spread.
- Wettest month
- February, 3.9"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, March (66% 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 Northridge Cal State, it arrives in quantity
14.6" of precipitation falls across only about 36 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 36 a year, 10% of all days
- Average depth per wet day
- 0.41 inches
- Most wet days
- February, about 7
- Fewest wet days
- July, about 0
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.
Northridge Cal State's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Scarce-water calendar
Where Northridge Cal State's limited precipitation lands
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 14.6 inches annually, within PlainClimate's dry band. Recorded annual snowfall is negligible. The monthly distribution matters because the total alone does not reveal the timing.
The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 21.8°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 66°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Northridge Cal State combines a compact 21.8°F annual temperature range with meaningful demand on both sides of the thermostat: 1,273 heating and 1,711 cooling degree days. The balance matters more here than either annual total in isolation.
A frost-free growing-season length is not available for Northridge Cal State. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.

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 Northridge Cal State; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
