“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 Lake
Lake gets 14 inches of rain and melted snow a year. August is the wettest month and June the driest. Rain or snow falls on about 77 days a year. Snow covers the ground about 116 days of the year.
About 101 frost-free days a year
In half of years the last 32° night comes by June 8 and the first one by September 17. That leaves about 101 frost-free days for gardens, shorter than 99% of U.S. towns.
Heating and cooling a home in Lake
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In 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.
How Lake compares
Compared with every U.S. town and city on TownTapestry, each counted once.
Warmer than it used to be
The last 30 years in Lake averaged 1.9° warmer than the 1900s. The biggest change is in March (+3.2°). The shift is larger than in 91% of U.S. towns.
Change by month1991–2020 average minus 1901–2000 average, at Lake’s spot on NOAA’s grid
How much a month can swing
A normal is an average, and real years wander around it. November swings the most: between 1991 and 2020 its average temperature ranged from 21° to 36°. August is the most reliable, staying within 7°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Lake itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Rio Grande Rsvr, CO (21 mi, snow) and Lake City, CO (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.
