The year, day by day
The year in Oracle runs from a mild 35°F around December 21 to 93°F at the peak near June 23, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 5 through August 4, covering 61 dates. The broader mild season, normal highs of 70°F or more, runs April 13 to November 2.
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 21.
Where the wet dates fall
The likeliest wet date is August 9, when 38% of years recorded at least a hundredth of an inch. The driest is April 30 at 6%. Summed across the calendar, that is about 67 wet dates a year.
The widest day
June 9 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Oracle runs a summer-peaked wet season
39% of Oracle's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is July at 4.3", on a 34.9°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: July, August, January, taking 48% of the annual total between them.
- Driest month: June at 0.3".
- Winter share: 29% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
How Oracle's precipitation splits across the calendar
About 67 days a year record measurable precipitation here, carrying 21.7" between them, or roughly 0.33 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 Oracle, but rarely amounts to much
The normals record 10.8 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 4 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 Oracle's climate pattern fits together
mixed demand · moderate · mid swing
July and December mark the typical warm and cold ends of the calendar in Oracle's middle-range seasonal profile. The measured spread is 34.9°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Oracle's normal, at 2,811 and 1,845 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.
The frost-free window extends for about 244 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Oracle's 21.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 10.8 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Oracle's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Oracle, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
