The year, day by day
Libby 1 NE Ranger Station works both ends of the calendar. Normal highs climb to 93°F by July 29 and hold at or above 90°F on 31 dates, then normal lows drop to freezing or below on 178 dates, bottoming at 20°F around December 25.
When the heat sits
Normal highs reach 90°F from July 17 through August 16, covering 31 dates. The broader mild season, normal highs of 70°F or more, runs May 8 to September 29.
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 April 19, then returns to freezing around October 25, covering 178 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 4, when 48% of years recorded at least a hundredth of an inch. The driest is August 8 at 18%. Summed across the calendar, that is about 125 wet dates a year.
The widest day
August 4 carries the biggest normal gap between afternoon and dawn, 43°F between the normal high and the normal low.

Libby 1 NE Ranger Station 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 30%, with neither reaching the 35% that would mark a distinct wet season. Libby 1 NE Ranger Station has no dry season to plan around, though it does carry a 41.9°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 2.5" and August 0.7". The three wettest months together take 36% 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.
Rain reaches Libby 1 NE Ranger Station in small, frequent amounts
Libby 1 NE Ranger Station records about 125 days with measurable precipitation a year and 19.1" in total, which works out to roughly 0.15 inches on an average wet day. Precipitation on 34% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: January, about 14 of them.
- Fewest: August, about 5.
- Average depth per wet day: 0.15 inches.
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 Libby 1 NE Ranger Station
Libby 1 NE Ranger Station averages 48.2 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 24 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: 48.2 inches of depth.
- Days recording measurable snow: about 24 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 25% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Libby 1 NE Ranger Station
heating led · dry · mid swing
Libby 1 NE Ranger Station's energy balance leans toward cold weather: 6,774 annual heating degree days against 379 for cooling. Its 41.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 121 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.

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 Libby 1 NE Ranger Station; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
