The year, day by day
Halfway works both ends of the calendar. Normal highs climb to 92°F by July 26 and hold at or above 90°F on 28 dates, then normal lows drop to freezing or below on 156 dates, bottoming at 19°F around January 1.
When the heat sits
Normal highs reach 90°F from July 15 through August 11, covering 28 dates. The broader mild season, normal highs of 70°F or more, runs May 11 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 24, then returns to freezing around October 21, covering 156 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 January 7, when 41% of years recorded at least a hundredth of an inch. The driest is July 29 at 9%. Summed across the calendar, that is about 99 wet dates a year.
The widest day
August 3 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Halfway Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.

Halfway's wet season runs through the cold months
December, January and February carry 44% of the year's precipitation here, while June through August contribute 10%. 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 45.4°F gap between its warmest and coldest month.
- Wettest month
- December, 3.8"
- Driest month
- August, 0.3"
- Wettest three months
- December, January, November (47% 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.
How Halfway's precipitation splits across the calendar
About 99 days a year record measurable precipitation here, carrying 21.3" between them, or roughly 0.22 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 Halfway
Halfway averages 62.3 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 21 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: 62.3 inches of depth.
- Days recording measurable snow: about 21 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 29% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Halfway
heating led · moderate · mid swing
Halfway's energy balance leans toward cold weather: 6,656 annual heating degree days against 450 for cooling. Its 45.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 132 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.
