About 135 frost-free days a year
In half of years the last 32° night comes by May 22 and the first one by October 4. That leaves about 135 frost-free days for gardens, shorter than 92% of U.S. towns.
Heating and cooling a home in Mitchell
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Mitchell, 95% of that work is heating and 5% 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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Mitchell itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Mitchell 2 E, OR (2 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
