“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 Mariposa
Mariposa gets 31 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 72 days a year. Snow covers the ground about 41 days of the year.
About 174 frost-free days a year
In half of years the last 32° night comes by April 23 and the first one by October 13. That leaves about 174 frost-free days for gardens, shorter than 56% of U.S. towns.
Heating and cooling a home in Mariposa
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Mariposa, 87% of that work is heating and 13% 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.
Mariposa and its neighbors
Mariposa borders 4 towns with climate data. January nights across them vary by 0.2°. Chapman has both the coldest January nights (14°) and the hottest July afternoons (87°). Mariposa’s January low is 14° and its July high 87°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.

Temperatures and rainfall come from NOAA’s gridded climate normals for Mariposa itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Prague, NE (5 mi, snow) and Weston 3nw, NE (4 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
