The year, day by day
The calendar barely moves in Imperial Beach Ream Fld: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 46°F near December 12 and 76°F near August 25.
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 12.
The widest day
December 2 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Where Imperial Beach Ream Fld Stands Nationally
Aridity defines the water calendar: about 9 inches in a normal year lands this among the driest tenth of ranked stations.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 20°F.
Imperial Beach Ream Fld earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Imperial Beach Ream Fld's wet season runs through the cold months
December, January and February carry 49% of the year's precipitation here, while June through August contribute 5%. 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 13.8°F seasonal spread.
- Wettest month
- February, 2.1"
- Driest month
- August, 0.0"
- Wettest three months
- February, March, January (66% 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.

Scarce-water calendar
Where Imperial Beach Ream Fld's limited precipitation lands
heating led · dry · low swing
Heating is the larger measured load in Imperial Beach Ream Fld, at 1,482 degree days versus 520 for cooling. Unlike a strongly continental record, however, its 13.8°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
A frost-free growing-season length is not available for Imperial Beach Ream Fld. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 13.8°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 62°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Imperial Beach Ream Fld's cold-season load does not imply a wet climate. Annual precipitation is 8.6 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Imperial Beach Ream Fld's primary station: IMPERIAL BEACH REAM FLD NAS (USW00093115). 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 Imperial Beach Ream 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 Imperial Beach Ream Fld comes from its primary NOAA station record.
