Rain and snow in Santa Clara
Santa Clara gets 42 inches of rain and melted snow a year. December is the wettest month and July the driest. Rain or snow falls on about 166 days a year.
About 196 frost-free days a year
In half of years the last 32° night comes by April 11 and the first one by October 23. That leaves about 196 frost-free days for gardens, longer than 70% of U.S. towns.
Heating and cooling a home in Santa Clara
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Santa Clara, 94% of that work is heating and 6% 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 Santa Clara itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Leaburg 1 Sw, OR (22 mi, snow) and Eugene Mahlon Sweet Airport, OR (4 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.
