The year, day by day
Dull Ctr works both ends of the calendar. Normal highs climb to 91°F by July 24 and hold at or above 90°F on 24 dates, then normal lows drop to freezing or below on 186 dates, bottoming at 14°F around December 25.
When the heat sits
Normal highs reach 90°F from July 14 through August 6, covering 24 dates. The broader mild season, normal highs of 70°F or more, runs May 20 to September 30.
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 20, then returns to freezing around October 18, covering 186 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 27, when 31% of years recorded at least a hundredth of an inch. The driest is November 6 at 13%. Summed across the calendar, that is about 71 wet dates a year.
The widest day
September 2 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Dull Ctr Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 186 nights a year, more than most ranked stations.
A drier-than-most normal water year — around 14 inches, below what four out of five ranked stations collect.

Dull Ctr runs a summer-peaked wet season
37% of Dull Ctr'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 2.5", on a wide 47.3°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: May, June, July, taking 46% of the annual total between them.
- Driest month: January at 0.3".
- 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.
Dull Ctr is dry, and what does fall arrives gently
Only about 71 days a year record measurable precipitation here, 19% of the calendar, and they carry 13.7" between them. At roughly 0.19 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 9 wet days; the driest is November 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.
Winter brings real snow to Dull Ctr
Dull Ctr averages 46.8 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 29 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.
- Annual snowfall: 46.8 inches of depth.
- Days recording measurable snow: about 29 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 34% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Dull Ctr
heating led · dry · mid swing
Dull Ctr's energy balance leans toward cold weather: 6,962 annual heating degree days against 642 for cooling. Its 47.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 135 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.

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 Dull Ctr; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
