The year, day by day
Montrose Rgnl works both ends of the calendar. Normal highs climb to 90°F by July 11 and hold at or above 90°F on 19 dates, then normal lows drop to freezing or below on 158 dates, bottoming at 14°F around January 1.
When the heat sits
Normal highs reach 90°F from July 5 through July 23, covering 19 dates. The broader mild season, normal highs of 70°F or more, runs May 8 to October 5.
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 April 1, then returns to freezing around October 27, covering 158 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 July 31, when 25% of years recorded at least a hundredth of an inch. The driest is June 8 at 12%. Summed across the calendar, that is about 72 wet dates a year.
The widest day
June 22 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Montrose Rgnl Stands Nationally
Aridity defines the water calendar: about 8 inches in a normal year lands this among the driest tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Montrose Rgnl earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Montrose Rgnl spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 16%, with neither reaching the 35% that would mark a distinct wet season. Montrose Rgnl has no dry season to plan around, though it does carry a wide 46.8°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: September averages 1.2" and June 0.4". The three wettest months together take 37% 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.
Montrose Rgnl is dry, and what does fall arrives gently
Only about 72 days a year record measurable precipitation here, 20% of the calendar, and they carry 8.3" between them. At roughly 0.12 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 7 wet days; the driest is June at about 3.
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 Montrose Rgnl's limited precipitation lands
heating led · dry · mid swing
Montrose Rgnl's energy balance leans toward cold weather: 6,017 annual heating degree days against 700 for cooling. Its 46.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Montrose Rgnl's frost-free season lasts about 159 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Montrose Rgnl's middle-range seasonal profile. The measured spread is 46.8°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Montrose Rgnl's cold-season load does not imply a wet climate. Annual precipitation is 8.3 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Montrose Rgnl's primary station: MONTROSE RGNL AP (USW00093013). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Montrose Rgnl; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Montrose Rgnl comes from its primary NOAA station record.
