The year, day by day

The calendar barely moves in Anaheim: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 48°F near December 16 and 89°F near August 26.

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 48°F around December 16.

Where the wet dates fall

The likeliest wet date is February 20, when 22% of years recorded at least a hundredth of an inch. The driest is August 10 at 1%. Summed across the calendar, that is about 35 wet dates a year.

The widest day

October 27 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Anaheim's wet season runs through the cold months

December, January and February carry 64% of the year's precipitation here, while June through August contribute 2%. 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 18°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 Anaheim, it arrives in quantity

13.5" of precipitation falls across only about 35 wet days here, averaging 0.39 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

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.

Anaheim'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 Anaheim's limited precipitation lands

cooling led · dry · low swing

Warm-season load persists through a relatively even calendar in Anaheim. Cooling totals 1,812 degree days, more than double the 792 heating measure, and the 18.0°F seasonal range is compact rather than sharply divided.

Heat demand sits beside limited local precipitation: Anaheim receives 13.5 inches in a normal year, inside PlainClimate's dry range. Recorded annual snowfall is negligible. Month-level precipitation is the useful check on when that small annual total arrives.

The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 18.0°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 68°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.

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

August is typically driest; arid stations are defined by when water is absent, not by a four-season grid.

Questions about Anaheim's climate

How dry is Anaheim?
Anaheim receives 13.5 inches of precipitation a year, spread across roughly 35 days that record any measurable amount. For reference, the contiguous United States averages near 30 inches. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Anaheim get?
Anaheim averages about 47 days a year at or above 90°F, concentrated in August and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Anaheim?
Anaheim has 792 heating degree days and 1,812 cooling degree days annually, a cooling-dominated climate. Degree-day definitions: reading weather data.
