The year, day by day

The year in Riverside Citrus Exp runs from a mild 43°F around December 12 to 98°F at the peak near August 26, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from June 25 through September 24, covering 92 dates. The broader mild season, normal highs of 70°F or more, runs February 20 to December 7.

This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.

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 43°F around December 12.

Where the wet dates fall

The likeliest wet date is February 19, when 25% of years recorded at least a hundredth of an inch. The driest is August 17 at 1%. Summed across the calendar, that is about 38 wet dates a year.

The widest day

September 1 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Riverside Citrus Exp Stands Nationally

Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.

Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 92 days a year, more than four out of five ranked stations record.

Riverside Citrus Exp earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Riverside Citrus Exp's wet season runs through the cold months

December, January and February carry 61% 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 24°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 Riverside Citrus Exp's precipitation splits across the calendar

About 38 days a year record measurable precipitation here, carrying 9.9" between them, or roughly 0.26 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.

Riverside Citrus Exp'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 Riverside Citrus Exp's limited precipitation lands

mixed demand · dry · low swing

Local precipitation is sparse in this otherwise mixed profile. The station reports 9.9 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 24.0°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 67°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.

Riverside Citrus Exp combines a compact 24.0°F annual temperature range with meaningful demand on both sides of the thermostat: 1,266 heating and 1,857 cooling degree days. The balance matters more here than either annual total in isolation.

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

Questions about Riverside Citrus Exp's climate

How dry is Riverside Citrus Exp?
Riverside Citrus Exp receives 9.9 inches of precipitation a year, spread across roughly 38 days that record any measurable amount. For reference, the contiguous United States averages near 30 inches. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Riverside Citrus Exp get?
Riverside Citrus Exp averages about 103 days a year at or above 90°F, concentrated in August and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Riverside Citrus Exp?
Riverside Citrus Exp has 1,266 heating degree days and 1,857 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Riverside Citrus Exp's primary station: RIVERSIDE CITRUS EXP (USC00047473). 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 Riverside Citrus Exp; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
