The year, day by day
The calendar barely moves in San Diego Montgomery Fld: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 45°F near December 17 and 83°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 45°F around December 17.
Where the wet dates fall
The likeliest wet date is February 19, when 29% of years recorded at least a hundredth of an inch. The driest is July 5 at 2%. Summed across the calendar, that is about 50 wet dates a year.
The widest day
November 14 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where San Diego Montgomery Fld Stands Nationally
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
San Diego Montgomery Fld earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

San Diego Montgomery Fld's wet season runs through the cold months
December, January and February carry 60% 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 17.4°F seasonal spread.
- Wettest month
- February, 2.6"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, March (60% 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 San Diego Montgomery Fld's precipitation splits across the calendar
About 50 days a year record measurable precipitation here, carrying 11.0" between them, or roughly 0.22 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 San Diego Montgomery Fld's limited precipitation lands
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 11.0 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 17.4°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.
San Diego Montgomery Fld combines a compact 17.4°F annual temperature range with meaningful demand on both sides of the thermostat: 1,320 heating and 1,019 cooling degree days. The balance matters more here than either annual total in isolation.
A frost-free growing-season length is not available for San Diego Montgomery Fld. 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 San Diego Montgomery Fld's primary station: SAN DIEGO MONTGOMERY FLD (USW00003131). 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 San Diego Montgomery Fld; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for San Diego Montgomery Fld comes from its primary NOAA station record.
