About 174 frost-free days a year

Heating and cooling a home in Weiser
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Weiser, 85% of that work is heating and 15% 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 Weiser itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Malheur Branch Exp Stn, OR (19 mi, snow) and Weiser, ID (1 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
