“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 Del Norte
Del Norte gets 10 inches of rain and melted snow a year. August is the wettest month and January the driest. Rain or snow falls on about 72 days a year. Snow covers the ground about 63 days of the year.
About 123 frost-free days a year
In half of years the last 32° night comes by May 23 and the first one by September 25. That leaves about 123 frost-free days for gardens, shorter than 97% of U.S. towns.
Heating and cooling a home in Del Norte
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Del Norte, 99% of that work is heating and 1% 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 Del Norte itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Del Norte 3ene, CO (3 mi) away. Normals are 30-year averages, not a forecast.
