“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 Summerset
Summerset gets 21 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 67 days a year. Snow covers the ground about 28 days of the year.
About 147 frost-free days a year
In half of years the last 32° night comes by May 10 and the first one by October 5. That leaves about 147 frost-free days for gardens, shorter than 83% of U.S. towns.
Heating and cooling a home in Summerset
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Summerset, 94% of that work is heating and 6% 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.
Summerset and its neighbors
Summerset borders 3 towns with climate data. January nights across them vary by 0.9°. Piedmont has both the coldest January nights (13°) and the hottest July afternoons (85°). Summerset’s January low is 14° and its July high 84°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Summerset 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 Summerset averaged 1.4° warmer than the 1900s. The biggest change is in January (+3.8°). The shift is larger than in 62% of U.S. towns.
Change by month1991–2020 average minus 1901–2000 average, at Summerset’s spot on NOAA’s grid
How much a month can swing
A normal is an average, and real years wander around it. February swings the most: between 1991 and 2020 its average temperature ranged from 11° to 37°. August is the most reliable, staying within 10°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Summerset itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Rapid City 4nw, SD (6 mi) away. Normals are 30-year averages, not a forecast.
