Rain and snow in Deer Lake
Deer Lake gets 20 inches of rain and melted snow a year. July is the wettest month and January the driest. Rain or snow falls on about 95 days a year.
About 138 frost-free days a year
In half of years the last 32° night comes by May 11 and the first one by September 28. That leaves about 138 frost-free days for gardens, shorter than 90% of U.S. towns.
Heating and cooling a home in Deer Lake
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Deer Lake, 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 Deer Lake itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Jamestown State Hosp, ND (20 mi, snow) and Jamestown Municipal Airport, ND (19 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.
