Methodology

Across 49 complete annual observations from 1959 to 2025, NEWHALEM warmed at a fitted rate of 0.20°C per decade. The line shows the fitted change relative to its first year, not raw year-to-year temperatures or a forecast.

The year, day by day

Summer here tops out rather than builds: the warmest normal high is 81°F around July 31, short of 90°F on every date, while 25 dates carry a normal low at or below freezing, the coldest 32°F near December 29.

The freezing stretch

The normal low stays at or below 32°F into January 12, then returns to freezing around December 19, covering 25 dates in all.

Where the wet dates fall

The likeliest wet date is November 15, when 67% of years recorded at least a hundredth of an inch. The driest is July 31 at 18%. Summed across the calendar, that is about 177 wet dates a year.

The widest day

July 27 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Newhalem's wet season runs through the cold months

December, January and February carry 40% of the year's precipitation here, while June through August contribute 7%. 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 30.4°F seasonal spread.

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.

When it rains in Newhalem, it arrives in quantity

78.8" of precipitation falls across only about 177 wet days here, averaging 0.45 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Winter brings real snow to Newhalem

Newhalem averages 29.5 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 12 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.

Snow and freeze rhythm

When cold and snow define Newhalem

heating led · wet · mid swing

Newhalem's energy balance leans toward cold weather: 5,644 annual heating degree days against 257 for cooling. Its 30.4°F seasonal range still makes the monthly rows more useful than the annual average alone.

Newhalem's frost-free season lasts about 226 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

  1. 1. Newhalem coldest normal

    December

    The monthly mean of 36°F (2°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.

  2. 2. Newhalem typical freeze period

    January through December

    The station reports average freezing days from January through December.

  3. 3. Newhalem snow peak

    January

    Newhalem averages 29.5 inches of snow a year, with January the snowiest month on the normals.

Questions about Newhalem's climate

How much snow does Newhalem get?
Newhalem averages 29.5 inches of snow a year, most of it in January, within 78.8 inches of total precipitation. Snowfall is depth on the ground; the precipitation total counts its liquid equivalent, so the two are not additive.
How much energy does heating and cooling require in Newhalem?
Newhalem has 5,644 heating degree days and 257 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Newhalem's primary station: NEWHALEM (USC00455840). 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 Newhalem; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
