The year, day by day
The calendar barely moves in Oceanside Marina: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 46°F near December 17 and 72°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 17.
Where the wet dates fall
The likeliest wet date is February 20, when 21% of years recorded at least a hundredth of an inch. The driest is August 16 at 1%. Summed across the calendar, that is about 34 wet dates a year.
The widest day
December 9 carries the biggest normal gap between afternoon and dawn, 17°F between the normal high and the normal low.

Where Oceanside Marina Stands Nationally
Aridity defines the water calendar: about 10 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 17°F.
Oceanside Marina earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Oceanside Marina'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 13.5°F seasonal spread.
- Wettest month
- February, 2.4"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, December (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 Oceanside Marina's precipitation splits across the calendar
About 34 days a year record measurable precipitation here, carrying 10.3" between them, or roughly 0.31 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.
Oceanside Marina'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 Oceanside Marina's limited precipitation lands
heating led · dry · low swing
Heating is the larger measured load in Oceanside Marina, at 1,827 degree days versus 342 for cooling. Unlike a strongly continental record, however, its 13.5°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 Oceanside Marina. 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 13.5°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 61°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Oceanside Marina's cold-season load does not imply a wet climate. Annual precipitation is 10.3 inches, which places the station in PlainClimate's dry range. Recorded annual snowfall is negligible. 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 Oceanside Marina's primary station: OCEANSIDE MARINA (USC00046377). 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 Oceanside Marina; 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 Oceanside Marina comes from its primary NOAA station record.
