The year, day by day
The year in Redlands runs from a mild 40°F around December 15 to 96°F at the peak near August 14, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 20 through September 23, covering 96 dates. The broader mild season, normal highs of 70°F or more, runs March 11 to November 30.
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 15.
Where the wet dates fall
The likeliest wet date is February 20, when 27% of years recorded at least a hundredth of an inch. The driest is June 27 at 2%. Summed across the calendar, that is about 44 wet dates a year.
The widest day
August 31 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Redlands Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 96 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Redlands earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Redlands'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 2%. 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 26.3°F seasonal spread.
- Wettest month
- February, 3.0"
- Driest month
- August, 0.1"
- Wettest three months
- February, January, March (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 Redlands's precipitation splits across the calendar
About 43 days a year record measurable precipitation here, carrying 12.9" between them, or roughly 0.30 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.
Redlands'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 Redlands's limited precipitation lands
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 12.9 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 26.3°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 65°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Redlands combines a compact 26.3°F annual temperature range with meaningful demand on both sides of the thermostat: 1,647 heating and 1,751 cooling degree days. The balance matters more here than either annual total in isolation.
Redlands has a long frost-free window of roughly 326 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
