The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 23, short of 90°F on every date, while 195 dates carry a normal low at or below freezing, the coldest 17°F near December 20.
The freezing stretch
The normal low stays at or below 32°F into May 1, then returns to freezing around October 20, covering 195 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 February 16, when 22% of years recorded at least a hundredth of an inch. The driest is June 27 at 7%. Summed across the calendar, that is about 55 wet dates a year.
The widest day
June 28 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Any date's 1991–2020 normal for Eureka.
Where Eureka Stands Nationally
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 195 nights a year, more than most ranked stations.
Eureka earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Eureka spreads its precipitation across the year
Neither half of the year dominates here: June through August take 15% of the annual total and December through February 28%, with neither reaching the 35% that would mark a distinct wet season. Eureka has no dry season to plan around, though it does carry a 42.1°F seasonal spread.
The gap between the wettest and driest month still matters: April averages 1.4" and July 0.5". The three wettest months together take 37% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
Eureka is dry, and what does fall arrives gently
Only about 55 days a year record measurable precipitation here, 15% of the calendar, and they carry 10.9" between them. At roughly 0.20 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 April at about 6 wet days; the driest is June 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 Eureka
Eureka averages 47.3 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 14 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: 47.3 inches of depth.
- Days recording measurable snow: about 14 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 44% 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 Eureka
heating led · dry · mid swing
Eureka's energy balance leans toward cold weather: 7,155 annual heating degree days against 334 for cooling. Its 42.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 119 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.

1. Eureka coldest normal
December
The monthly mean of 27°F (-3°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Eureka typical freeze period
