The year, day by day

Denver-stapleton works both ends of the calendar. Normal highs climb to 91°F by July 16 and hold at or above 90°F on 24 dates, then normal lows drop to freezing or below on 165 dates, bottoming at 17°F around December 23.

When the heat sits

Normal highs reach 90°F from July 8 through July 31, covering 24 dates. The broader mild season, normal highs of 70°F or more, runs May 13 to October 7.

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 8, then returns to freezing around October 27, covering 165 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 May 20, when 34% of years recorded at least a hundredth of an inch. The driest is January 1 at 15%. Summed across the calendar, that is about 84 wet dates a year.

The widest day

September 12 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Denver-stapleton runs a summer-peaked wet season

37% of Denver-stapleton'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 May at 2.3", on a 43°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.

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.

Denver-stapleton is dry, and what does fall arrives gently

Only about 84 days a year record measurable precipitation here, 23% of the calendar, and they carry 15.4" 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 May at about 11 wet days; the driest is December at about 5.

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.

Winter brings real snow to Denver-stapleton

Denver-stapleton averages 49.0 inches of snowfall a year, with March the snowiest month on the normals, spread across roughly 31 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.

Snow and freeze rhythm

When cold and snow define Denver-stapleton

heating led · dry · mid swing

Denver-stapleton's energy balance leans toward cold weather: 5,765 annual heating degree days against 813 for cooling. Its 43.0°F seasonal range still makes the monthly rows more useful than the annual average alone.

Denver-stapleton's frost-free season lasts about 157 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

  1. 1. Denver-stapleton coldest normal

    December

    The monthly mean of 32°F (0°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.

Questions about Denver-stapleton's climate

How much snow does Denver-stapleton get?
Denver-stapleton averages 49.0 inches of snow a year, most of it in March, within 15.4 inches of total precipitation. Snowfall is depth on the ground; the precipitation total counts its liquid equivalent, so the two are not additive.
How many days above 90°F does Denver-stapleton get?
Denver-stapleton averages about 42 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Denver-stapleton?
Denver-stapleton has 5,765 heating degree days and 813 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.

Data Sources

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 Denver-stapleton; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
