The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 29, short of 90°F on every date, while 240 dates carry a normal low at or below freezing, the coldest 7°F near December 23.
The freezing stretch
The normal low stays at or below 32°F into May 15, then returns to freezing around September 19, covering 240 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 6, when 33% of years recorded at least a hundredth of an inch. The driest is March 19 at 14%. Summed across the calendar, that is about 68 wet dates a year.
The widest day
August 2 carries the biggest normal gap between afternoon and dawn, 41°F between the normal high and the normal low.

Where Ovando Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 240 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 12 inches in a normal year lands this among the driest tenth of ranked stations.
Ovando earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Ovando spreads its precipitation across the year
Neither half of the year dominates here: June through August take 33% of the annual total and December through February 17%, with neither reaching the 35% that would mark a distinct wet season. Ovando has no dry season to plan around, though it does carry a 43.1°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 2.0" and February 0.4". The three wettest months together take 39% 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.
Ovando is dry, and what does fall arrives gently
Only about 67 days a year record measurable precipitation here, 18% of the calendar, and they carry 11.8" between them. At roughly 0.18 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 June at about 10 wet days; the driest is February at about 4.
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.

Scarce-water calendar
Where Ovando's limited precipitation lands
heating led · dry · mid swing
Ovando's energy balance leans toward cold weather: 9,521 annual heating degree days against 43 for cooling. Its 43.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
A frost-free growing-season length is not available for Ovando. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
July and December mark the typical warm and cold ends of the calendar in Ovando's middle-range seasonal profile. The measured spread is 43.1°F. The annual average is 39°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Ovando's cold-season load does not imply a wet climate. Annual precipitation is 11.8 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.

February is typically driest; arid stations are defined by when water is absent, not by a four-season grid.

The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 3056125), not an incorporated municipality. Match rule for Ovando: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
