The year, day by day

The calendar barely moves in Los Angeles: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 49°F near December 18 and 77°F near August 28.

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 49°F around December 18.

Where the wet dates fall

The likeliest wet date is February 18, when 22% of years recorded at least a hundredth of an inch. The driest is August 18 at 1%. Summed across the calendar, that is about 35 wet dates a year.

The widest day

November 19 carries the biggest normal gap between afternoon and dawn, 18°F between the normal high and the normal low.

Los Angeles'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 13.1°F seasonal spread.

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 Los Angeles, it arrives in quantity

12.2" of precipitation falls across only about 35 wet days here, averaging 0.35 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

Scarce-water calendar

Where Los Angeles's limited precipitation lands

mixed demand · dry · low swing

Local precipitation is sparse in this otherwise mixed profile. The station reports 12.2 inches annually, within PlainClimate's dry band. Snowfall is not added to the interpretation because its annual value is missing. 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 13.1°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 64°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.

Los Angeles combines a compact 13.1°F annual temperature range with meaningful demand on both sides of the thermostat: 1,214 heating and 720 cooling degree days. The balance matters more here than either annual total in isolation.

A frost-free growing-season length is not available for Los Angeles. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
