Rain and snow in Tower
Tower gets 22 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 84 days a year.
About 136 frost-free days a year
In half of years the last 32° night comes by May 13 and the first one by September 26. That leaves about 136 frost-free days for gardens, shorter than 92% of U.S. towns.
Heating and cooling a home in Tower
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Tower, 96% of that work is heating and 4% 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 Tower itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Casselton Agronomy Farm, ND (21 mi, snow) and Valley City 3 Nnw, ND (16 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.
