The year, day by day

The year in Morongo Valley N runs from a mild 40°F around December 18 to 95°F at the peak near August 5, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from June 19 through September 9, covering 83 dates. The broader mild season, normal highs of 70°F or more, runs April 3 to November 8.

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 40°F around December 18.

Where the wet dates fall

The likeliest wet date is December 22, when 14% of years recorded at least a hundredth of an inch. The driest is June 6 at 1%. Summed across the calendar, that is about 24 wet dates a year.

The widest day

May 4 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Morongo Valley N Stands Nationally

Aridity defines the water calendar: about 9 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 83 days a year, more than four out of five ranked stations record.

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

Morongo Valley N's wet season runs through the cold months

December, January and February carry 76% 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 a 32.7°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.

When it rains in Morongo Valley N, it arrives in quantity

9.4" of precipitation falls across only about 24 wet days here, averaging 0.39 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

Scarce-water calendar

Where Morongo Valley N's limited precipitation lands

mixed demand · dry · mid swing

Local precipitation is sparse in this otherwise mixed profile. The station reports 9.4 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.

August and December mark the typical warm and cold ends of the calendar in Morongo Valley N's middle-range seasonal profile. The measured spread is 32.7°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Morongo Valley N's normal, at 2,217 and 2,077 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.

Morongo Valley N has a long frost-free window of roughly 293 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.

Questions about Morongo Valley N's climate

How dry is Morongo Valley N?
Morongo Valley N receives 9.4 inches of precipitation a year, spread across roughly 24 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 Morongo Valley N get?
Morongo Valley N averages about 91 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 Morongo Valley N?
Morongo Valley N has 2,217 heating degree days and 2,077 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 Morongo Valley N's primary station: MORONGO VALLEY N (USC00045860). 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 Morongo Valley N; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
