The freezing stretch

The normal low stays at or below 32°F into April 3, then returns to freezing around October 29, covering 158 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 May 24, when 41% of years recorded at least a hundredth of an inch. The driest is December 4 at 19%. Summed across the calendar, that is about 97 wet dates a year.

The widest day

July 26 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Billings Logan spreads its precipitation across the year

Neither half of the year dominates here: June through August take 30% of the annual total and December through February 12%, with neither reaching the 35% that would mark a distinct wet season. Billings Logan has no dry season to plan around, though it does carry a wide 46.3°F gap between its warmest and coldest month.

The gap between the wettest and driest month still matters: May averages 2.4" and January 0.6". The three wettest months together take 44% 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.

Billings Logan is dry, and what does fall arrives gently

Only about 97 days a year record measurable precipitation here, 27% of the calendar, and they carry 14.3" 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 May at about 12 wet days; the driest is August at about 6.

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.

Winter brings real snow to Billings Logan

Billings Logan averages 57.4 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 39 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.

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 Billings Logan

heating led · dry · mid swing

Billings Logan's energy balance leans toward cold weather: 6,754 annual heating degree days against 663 for cooling. Its 46.3°F seasonal range still makes the monthly rows more useful than the annual average alone.

Billings Logan's frost-free season lasts about 156 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

  1. 1. Billings Logan coldest normal

    January

    The monthly mean of 27°F (-3°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.

Questions about Billings Logan's climate

How much snow does Billings Logan get?
Billings Logan averages 57.4 inches of snow a year, most of it in January, within 14.3 inches of total precipitation. Snowfall is depth on the ground; the precipitation total counts its liquid equivalent, so the two are not additive.
How many days above 90°F does Billings Logan get?
Billings Logan averages about 32 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Billings Logan?
Billings Logan has 6,754 heating degree days and 663 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 Billings Logan's primary station: BILLINGS LOGAN INTL AP (USW00024033). 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 Billings Logan; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
