“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 Twin Lakes
Twin Lakes gets 12 inches of rain and melted snow a year. August is the wettest month and November the driest. Rain or snow falls on about 130 days a year.
About 85 frost-free days a year
In half of years the last 32° night comes by June 16 and the first one by September 10. That leaves about 85 frost-free days for gardens, shorter than 100% of U.S. towns.
Heating and cooling a home in Twin Lakes
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Twin Lakes, 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 Twin Lakes itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Leadville 1.4 Wnw, CO (11 mi, snow) and Twin Lakes Rsvr, CO (2 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.
