The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 15, short of 90°F on every date, while 216 dates carry a normal low at or below freezing, the coldest 8°F near December 26.
The freezing stretch
The normal low stays at or below 32°F into May 6, then returns to freezing around October 4, covering 216 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 August 3, when 40% of years recorded at least a hundredth of an inch. The driest is October 14 at 16%. Summed across the calendar, that is about 95 wet dates a year.
The widest day
June 24 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Eastonville Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 216 nights a year, placing this among the most frost-prone tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.
Eastonville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Eastonville runs a summer-peaked wet season
44% of Eastonville'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 July at 3.9", on a 40.5°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: July, August, May, taking 47% of the annual total between them.
- Driest month: December at 0.6".
- 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.
How Eastonville's precipitation splits across the calendar
About 95 days a year record measurable precipitation here, carrying 21.6" between them, or roughly 0.23 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 Eastonville
Eastonville averages 101.7 inches of snowfall a year, with April the snowiest month on the normals, spread across roughly 44 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: 101.7 inches of depth.
- Days recording measurable snow: about 44 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 47% 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 Eastonville
heating led · moderate · mid swing
Eastonville's energy balance leans toward cold weather: 7,770 annual heating degree days against 89 for cooling. Its 40.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 115 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 Eastonville; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
