What a year in Snowslip feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 88 frost-free days a year
In half of years the last 32° night comes by June 8 and the first by September 5. Frost and day counts come from NOAA’s station at E Glacier, MT, 16 miles from the town’s center, 380 ft higher.
The 2023 USDA map puts Snowslip’s center in zone 4b: the coldest night of a typical winter, averaged over 1991–2020, reaches about −21°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Snowslip
Nearly all of the work is heating: a normal year has almost no cooling days. Months averaging under 55° run from September through June.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at E Glacier, MT.
Living with Snowslip’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
88 frost-free days in zone 4b. The last frost comes by Jun 8 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Sep 5.
Months with highs of 62–84° and lows of 40° or more: June, July and August.

Warmer than it used to be
The last 30 years in Snowslip averaged 1.8° warmer than the 1900s. The biggest change is in January (+5.4°).
A bigger shift than in 81% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
How Snowslip compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Snowslip’s place among Montana’s.
