The year, day by day
Winslow works both ends of the calendar. Normal highs climb to 95°F by July 4 and hold at or above 90°F on 85 dates, then normal lows drop to freezing or below on 131 dates, bottoming at 21°F around December 22.
When the heat sits
Normal highs reach 90°F from June 7 through August 30, covering 85 dates. The broader mild season, normal highs of 70°F or more, runs April 7 to October 25.
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.
The freezing stretch
The normal low stays at or below 32°F into March 16, then returns to freezing around November 7, covering 131 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 August 7, when 26% of years recorded at least a hundredth of an inch. The driest is June 8 at 6%. Summed across the calendar, that is about 50 wet dates a year.
The widest day
June 9 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Winslow Stands Nationally
Aridity defines the water calendar: about 7 inches in a normal year lands this among the driest tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 38°F, sharper than nine in ten ranked stations see.

Winslow spreads its precipitation across the year
Neither half of the year dominates here: June through August take 34% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Winslow has no dry season to plan around, though it does carry a 43.9°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 1.2" and June 0.1". The three wettest months together take 45% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
Winslow is dry, and what does fall arrives gently
Only about 49 days a year record measurable precipitation here, 14% of the calendar, and they carry 6.5" between them. At roughly 0.13 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is August at about 8 wet days; the driest is June at about 2.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

What Winslow's climate means for you
Winslow runs 57°F a year - peaking in July, coldest in December.
- Gardeners work an ordinary 174-day frost-free window; the last spring freeze usually lands near April 27, so start dates matter.
- Keeping warm is the dominant household load: 4,330 heating degree days against only 1,329 for cooling.

How Winslow's climate pattern fits together
heating led · dry · mid swing
Winslow's energy balance leans toward cold weather: 4,330 annual heating degree days against 1,329 for cooling. Its 43.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Winslow's frost-free season lasts about 174 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Winslow's middle-range seasonal profile. The measured spread is 43.9°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Winslow's cold-season load does not imply a wet climate. Annual precipitation is 6.5 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Winslow'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. They are descriptive ranges, not an official NOAA classification or a forecast for any specific year.
The year in four calendar signals
- Warmest normal
- July
- At 79°F (26°C) this is a genuinely hot month, in the top third of US stations, and the daily average understates afternoon highs.
- Coldest normal
- December
- The monthly mean of 35°F (2°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
- Rainfall rhythm
- August to June
- August is typically wettest; June is driest.
- Mild-temperature window
- May through October
- Monthly means sit between 55°F and 75°F in this window. Freezing days are still reported from January through December.
