“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 Hidden Lake
Hidden Lake gets 20 inches of rain and melted snow a year. April is the wettest month and December the driest. Rain or snow falls on about 140 days a year. Snow covers the ground about 169 days of the year.
About 92 frost-free days a year
In half of years the last 32° night comes by June 14 and the first one by September 12. That leaves about 92 frost-free days for gardens, shorter than 99% of U.S. towns.
Heating and cooling a home in Hidden Lake
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Hidden Lake, 100% of that work is heating and 0% 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 Hidden Lake itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Ward 4.6 Ne, CO (2 mi, snow) and Allenspark 3nw, CO (9 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.
