The year, day by day
Ephrata Muni works both ends of the calendar. Normal highs climb to 91°F by July 26 and hold at or above 90°F on 24 dates, then normal lows drop to freezing or below on 132 dates, bottoming at 22°F around January 1.
When the heat sits
Normal highs reach 90°F from July 16 through August 8, covering 24 dates. The broader mild season, normal highs of 70°F or more, runs May 5 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 March 16, then returns to freezing around November 6, covering 132 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 December 13, when 33% of years recorded at least a hundredth of an inch. The driest is August 16 at 6%. Summed across the calendar, that is about 71 wet dates a year.
The widest day
August 24 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Where Ephrata Muni Stands Nationally
Aridity defines the water calendar: about 8 inches in a normal year lands this among the driest tenth of ranked stations.

Ephrata Muni's wet season runs through the cold months
December, January and February carry 35% of the year's precipitation here, while June through August contribute 15%. 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 wide 45.7°F gap between its warmest and coldest month.
- Wettest month
- December, 1.1"
- Driest month
- August, 0.2"
- Wettest three months
- December, January, November (38% 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.
Ephrata Muni is dry, and what does fall arrives gently
Only about 71 days a year record measurable precipitation here, 19% of the calendar, and they carry 7.6" between them. At roughly 0.11 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 December at about 10 wet days; the driest is August 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.

Where Ephrata Muni's limited precipitation lands
heating led · dry · mid swing
Ephrata Muni's energy balance leans toward cold weather: 5,753 annual heating degree days against 843 for cooling. Its 45.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Ephrata Muni's frost-free season lasts about 178 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Ephrata Muni's middle-range seasonal profile. The measured spread is 45.7°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Ephrata Muni's cold-season load does not imply a wet climate. Annual precipitation is 7.6 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Ephrata Muni's primary station: EPHRATA MUNI AP (USW00024141). For informational purposes only.
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 Ephrata Muni; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Ephrata Muni comes from its primary NOAA station record.
