The year, day by day
The year in Delano runs from a mild 36°F around December 18 to 98°F at the peak near July 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 9 through September 18, covering 102 dates. The broader mild season, normal highs of 70°F or more, runs March 23 to November 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 36°F around December 18.
Where the wet dates fall
The likeliest wet date is January 21, when 22% of years recorded at least a hundredth of an inch. The driest is July 1 at 0%. Summed across the calendar, that is about 36 wet dates a year.
The widest day
August 20 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Delano Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 102 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Aridity defines the water calendar: about 8 inches in a normal year lands this among the driest tenth of ranked stations.

Delano's wet season runs through the cold months
December, January and February carry 52% 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 a 35.6°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 Delano's precipitation splits across the calendar
About 36 days a year record measurable precipitation here, carrying 7.5" between them, or roughly 0.21 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.
Snow reaches Delano, but rarely amounts to much
The normals record 0.2 inches of snow a year here, most likely in January. 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.

Scarce-water calendar
Where Delano's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 7.5 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.
July and January mark the typical warm and cold ends of the calendar in Delano's middle-range seasonal profile. The measured spread is 35.6°F. The annual average is 64°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Delano's normal, at 2,282 and 2,036 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.
Delano has a long frost-free window of roughly 311 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
