The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 26, short of 90°F on every date, while 172 dates carry a normal low at or below freezing, the coldest 15°F near December 31.
The freezing stretch
The normal low stays at or below 32°F into April 14, then returns to freezing around October 26, covering 172 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 31, when 28% of years recorded at least a hundredth of an inch. The driest is December 5 at 9%. Summed across the calendar, that is about 59 wet dates a year.
The widest day
August 26 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Colony runs a summer-peaked wet season
37% of Colony'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 2.7", on a wide 48.6°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 47% of the annual total between them.
- Driest month: December at 0.3".
- Winter share: 8% 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.
How Colony's precipitation splits across the calendar
About 59 days a year record measurable precipitation here, carrying 14.2" between them, or roughly 0.24 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Colony
Colony averages 25.3 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 15 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: 25.3 inches of depth.
- Days recording measurable snow: about 15 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 18% 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 Colony
heating led · dry · mid swing
Colony's energy balance leans toward cold weather: 7,291 annual heating degree days against 629 for cooling. Its 48.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 149 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Colony's primary station: COLONY (USC00481905). 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 Colony; 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 Colony comes from its primary NOAA station record.
