The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 30, short of 90°F on every date, while 210 dates carry a normal low at or below freezing, the coldest 15°F near February 10.
The freezing stretch
The normal low stays at or below 32°F into May 6, then returns to freezing around October 10, covering 210 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 June 5, when 38% of years recorded at least a hundredth of an inch. The driest is February 3 at 12%. Summed across the calendar, that is about 73 wet dates a year.
The widest day
August 11 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Martinsdale Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 210 nights a year, placing this among the most frost-prone tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 38°F, sharper than nine in ten ranked stations see.
Martinsdale earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Martinsdale runs a summer-peaked wet season
38% of Martinsdale'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 June at 2.6", on a 38.8°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.
- Wettest three months: June, May, July, taking 48% of the annual total between them.
- Driest month: February at 0.3".
- Winter share: 10% 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.
Martinsdale 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 13.5" 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 June at about 11 wet days; the driest is February 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 Martinsdale
Martinsdale averages 43.4 inches of snowfall a year, with March the snowiest month on the normals, spread across roughly 25 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: 43.4 inches of depth.
- Days recording measurable snow: about 25 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 32% 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 Martinsdale
heating led · dry · mid swing
Martinsdale's energy balance leans toward cold weather: 7,878 annual heating degree days against 136 for cooling. Its 38.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 97 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.
