The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 27, short of 90°F on every date, while 158 dates carry a normal low at or below freezing, the coldest 21°F near December 20.
The freezing stretch
The normal low stays at or below 32°F into March 30, then returns to freezing around October 25, 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 January 7, when 31% of years recorded at least a hundredth of an inch. The driest is August 6 at 7%. Summed across the calendar, that is about 73 wet dates a year.
The widest day
July 25 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Odessa Stands Nationally
Aridity defines the water calendar: about 11 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 36°F between the normal high and low.
Odessa earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Odessa's wet season runs through the cold months
December, January and February carry 38% of the year's precipitation here, while June through August contribute 12%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 41.1°F seasonal spread.
- Wettest month
- December, 1.7"
- Driest month
- August, 0.2"
- Wettest three months
- December, January, November (41% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
Odessa is dry, and what does fall arrives gently
Only about 73 days a year record measurable precipitation here, 20% of the calendar, and they carry 11.1" between them. At roughly 0.15 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 January at about 9 wet days; the driest is July at about 2.
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 Odessa
Odessa averages 13.9 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 9 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: 13.9 inches of depth.
- Days recording measurable snow: about 9 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 13% 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 Odessa
heating led · dry · mid swing
Odessa's energy balance leans toward cold weather: 6,333 annual heating degree days against 433 for cooling. Its 41.1°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.
