The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 27, short of 90°F on every date, while 187 dates carry a normal low at or below freezing, the coldest -5°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into April 21, then returns to freezing around October 18, covering 187 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is June 16, when 39% of years recorded at least a hundredth of an inch. The driest is March 20 at 21%. Summed across the calendar, that is about 98 wet dates a year.
The widest day
May 12 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Ada Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 187 nights a year, more than most ranked stations.

Ada runs a summer-peaked wet season
46% of Ada'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 June at 4.6", on a wide 62.6°F gap between its warmest and coldest month. 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: June, July, August, taking 46% of the annual total between them.
- Driest month: February at 0.7".
- Winter share: 9% 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 Ada's precipitation splits across the calendar
About 97 days a year record measurable precipitation here, carrying 25.0" between them, or roughly 0.26 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.

Data-derived climate profile
How Ada's climate pattern fits together
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Ada logs 9,471 heating degree days, more than twice its 392 cooling total, while the typical coldest-to-warmest-month gap reaches 62.6°F. The annual mean therefore compresses two materially different seasons.
Only about 139 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
Ada's calendar has a pronounced split: July and January mark the typical warm and cold ends of the calendar, with 62.6°F between them. The annual average is 40°F. That average is context, while the monthly highs, lows, and precipitation totals describe the lived parts of the year.
Ada's 25.0 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Ada'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 Ada, not an official NOAA class or a year-ahead forecast.
