The year, day by day
The year in Ojai runs from a mild 33°F around December 13 to 92°F at the peak near August 18, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 25 through September 8, covering 46 dates. The broader mild season, normal highs of 70°F or more, runs March 18 to November 23.
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 33°F around December 13.
Where the wet dates fall
The likeliest wet date is February 18, when 27% of years recorded at least a hundredth of an inch. The driest is July 30 at 1%. Summed across the calendar, that is about 44 wet dates a year.
The widest day
August 28 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Ojai Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.

Ojai's wet season runs through the cold months
December, January and February carry 64% 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 23.1°F seasonal spread.
- Wettest month
- February, 5.2"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, March (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.
When it rains in Ojai, it arrives in quantity
20.7" of precipitation falls across only about 44 wet days here, averaging 0.47 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 44 a year, 12% of all days
- Average depth per wet day
- 0.47 inches
- Most wet days
- February, about 8
- Fewest wet days
- August, about 0
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Snow reaches Ojai, but rarely amounts to much
The normals record 0.1 inches of snow a year here, most likely in March. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 0 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Ojai's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Ojai, at 2,516 degree days versus 761 for cooling. Unlike a strongly continental record, however, its 23.1°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Ojai's frost-free season lasts about 239 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Temperature varies within a narrow 23.1°F band across the normal year. August and December mark the typical warm and cold ends of the calendar. The annual average is 60°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Ojai's 20.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Ojai's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Ojai, not an official NOAA class or a year-ahead forecast.
