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 23.

Where the wet dates fall

The likeliest wet date is February 23, when 26% of years recorded at least a hundredth of an inch. The driest is August 19 at 1%. Summed across the calendar, that is about 41 wet dates a year.

The widest day

November 5 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Santa Ana John Wayne's wet season runs through the cold months

December, January and February carry 65% 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 16.4°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.

How Santa Ana John Wayne's precipitation splits across the calendar

About 41 days a year record measurable precipitation here, carrying 11.2" 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.

Scarce-water calendar

Where Santa Ana John Wayne's limited precipitation lands

mixed demand · dry · low swing

Local precipitation is sparse in this otherwise mixed profile. The station reports 11.2 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 16.4°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.

Santa Ana John Wayne combines a compact 16.4°F annual temperature range with meaningful demand on both sides of the thermostat: 1,092 heating and 1,075 cooling degree days. The balance matters more here than either annual total in isolation.

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

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Santa Ana John Wayne's primary station: SANTA ANA JOHN WAYNE AP (USW00093184). For informational purposes only.

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 Santa Ana John Wayne; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
