The year, day by day
The calendar barely moves in Santa Ana Fire Stn: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 48°F near December 17 and 85°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 17.
Where the wet dates fall
The likeliest wet date is February 18, when 23% 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
November 11 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Santa Ana Fire Stn Stands Nationally
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.

Santa Ana Fire Stn'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 16.8°F seasonal spread.
- Wettest month
- February, 3.2"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, December (65% 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 Santa Ana Fire Stn, it arrives in quantity
12.5" of precipitation falls across only about 35 wet days here, averaging 0.36 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 35 a year, 10% of all days
- Average depth per wet day
- 0.36 inches
- Most wet days
- February, about 7
- Fewest wet days
- August, 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.
Santa Ana Fire Stn'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 Santa Ana Fire Stn's limited precipitation lands
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 12.5 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 16.8°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.
Santa Ana Fire Stn combines a compact 16.8°F annual temperature range with meaningful demand on both sides of the thermostat: 927 heating and 1,335 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 Fire Stn. 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 Santa Ana Fire Stn; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
