The year, day by day
The calendar barely moves in Long Beach: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 46°F near December 18 and 84°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 46°F around December 18.
Where the wet dates fall
The likeliest wet date is February 19, when 23% of years recorded at least a hundredth of an inch. The driest is August 16 at 1%. Summed across the calendar, that is about 35 wet dates a year.
The widest day
November 18 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Where Long Beach Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 21°F.
A drier-than-most normal water year — around 12 inches, below what four out of five ranked stations collect.
Long Beach earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Long Beach's wet season runs through the cold months
December, January and February carry 67% 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 17.6°F seasonal spread.
- Wettest month
- February, 3.0"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, December (67% 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 Long Beach's precipitation splits across the calendar
About 35 days a year record measurable precipitation here, carrying 12.0" between them, or roughly 0.34 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 Long Beach's limited precipitation lands
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 12.0 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 17.6°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 65°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Long Beach combines a compact 17.6°F annual temperature range with meaningful demand on both sides of the thermostat: 1,173 heating and 1,166 cooling degree days. The balance matters more here than either annual total in isolation.
A frost-free growing-season length is not available for Long Beach. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
