The year, day by day
Eureka Airport works both ends of the calendar. Normal highs climb to 91°F by July 20 and hold at or above 90°F on 29 dates, then normal lows drop to freezing or below on 211 dates, bottoming at 11°F around December 20.
When the heat sits
Normal highs reach 90°F from July 10 through August 7, covering 29 dates. The broader mild season, normal highs of 70°F or more, runs May 20 to October 3.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into May 4, then returns to freezing around October 7, covering 211 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 April 12, when 30% of years recorded at least a hundredth of an inch. The driest is June 25 at 11%. Summed across the calendar, that is about 76 wet dates a year.
The widest day
July 7 carries the biggest normal gap between afternoon and dawn, 41°F between the normal high and the normal low.

Where Eureka Airport Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 211 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 9 inches in a normal year lands this among the driest tenth of ranked stations.
Eureka Airport earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Eureka Airport spreads its precipitation across the year
Neither half of the year dominates here: June through August take 19% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Eureka Airport has no dry season to plan around, though it does carry a 44.5°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 1.2" and August 0.5". The three wettest months together take 35% 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 Airport is dry, and what does fall arrives gently
Only about 76 days a year record measurable precipitation here, 21% of the calendar, and they carry 9.1" between them. At roughly 0.12 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 10 wet days; the driest is June 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.

Scarce-water calendar
Where Eureka Airport's limited precipitation lands
heating led · dry · mid swing
Eureka Airport's energy balance leans toward cold weather: 7,156 annual heating degree days against 356 for cooling. Its 44.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 102 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.
July and December mark the typical warm and cold ends of the calendar in Eureka Airport's middle-range seasonal profile. The measured spread is 44.5°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Eureka Airport's cold-season load does not imply a wet climate. Annual precipitation is 9.1 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

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 Eureka Airport; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
