“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Star
Star gets 23 inches of rain and melted snow a year. June is the wettest month and February the driest.
About 120 frost-free days a year
In half of years the last 32° night comes by May 24 and the first one by September 20. That leaves about 120 frost-free days for gardens, shorter than 97% of U.S. towns.
Heating and cooling a home in Star
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Star, 97% of that work is heating and 3% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
Star and its neighbors
Star borders 3 towns with climate data. January nights across them vary by 0.2°. Reiner has the coldest January nights (-4°) and Hickory the hottest July afternoons (79°). Star’s January low is -4° and its July high 79°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Star compares
Compared with every U.S. town and city on TownTapestry, each counted once.
Warmer than it used to be
The last 30 years in Star averaged 1.7° warmer than the 1900s. The biggest change is in January (+4.4°). The shift is larger than in 79% of U.S. towns.

How much a month can swing
A normal is an average, and real years wander around it. January swings the most: between 1991 and 2020 its average temperature ranged from -7° to 22°. August is the most reliable, staying within 11°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Star itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Thorhult, MN (22 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
