The year, day by day
Emmett works both ends of the calendar. Normal highs climb to 94°F by July 26 and hold at or above 90°F on 41 dates, then normal lows drop to freezing or below on 134 dates, bottoming at 22°F around January 1.
When the heat sits
Normal highs reach 90°F from July 9 through August 18, covering 41 dates. The broader mild season, normal highs of 70°F or more, runs May 8 to October 7.
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 4, covering 134 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 11, when 37% of years recorded at least a hundredth of an inch. The driest is July 27 at 6%. Summed across the calendar, that is about 91 wet dates a year.
The widest day
July 26 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Emmett Stands Nationally
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.

Emmett's wet season runs through the cold months
December, January and February carry 39% of the year's precipitation here, while June through August contribute 9%. 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 43.9°F seasonal spread.
- Wettest month
- December, 2.1"
- Driest month
- August, 0.2"
- Wettest three months
- December, January, March (41% 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.
Emmett is dry, and what does fall arrives gently
Only about 91 days a year record measurable precipitation here, 25% of the calendar, and they carry 13.3" between them. At roughly 0.15 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 12 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.
Snow reaches Emmett, but rarely amounts to much
The normals record 7.4 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 6 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Scarce-water calendar
Where Emmett's limited precipitation lands
heating led · dry · mid swing
Emmett's energy balance leans toward cold weather: 5,689 annual heating degree days against 789 for cooling. Its 43.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Emmett's frost-free season lasts about 170 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 Emmett's middle-range seasonal profile. The measured spread is 43.9°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Emmett's cold-season load does not imply a wet climate. Annual precipitation is 13.3 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 7.4 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
