The year, day by day
The year in Ramona runs from a mild 35°F around December 13 to 91°F at the peak near August 21, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from August 3 through September 6, covering 35 dates. The broader mild season, normal highs of 70°F or more, runs April 4 to November 22.
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 35°F around December 13.
Where the wet dates fall
The likeliest wet date is February 20, when 29% of years recorded at least a hundredth of an inch. The driest is July 4 at 2%. Summed across the calendar, that is about 52 wet dates a year.
The widest day
September 2 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Ramona Stands Nationally
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Ramona earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Ramona'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 24.1°F seasonal spread.
- Wettest month
- February, 3.7"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, March (62% 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 Ramona's precipitation splits across the calendar
About 53 days a year record measurable precipitation here, carrying 14.6" between them, or roughly 0.28 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 Ramona's limited precipitation lands
heating led · dry · low swing
Heating is the larger measured load in Ramona, at 2,329 degree days versus 957 for cooling. Unlike a strongly continental record, however, its 24.1°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Ramona has a long frost-free window of roughly 249 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 24.1°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.
Ramona's cold-season load does not imply a wet climate. Annual precipitation is 14.7 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.
