“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 White Signal
White Signal gets 15 inches of rain and melted snow a year. July is the wettest month and April the driest. Rain or snow falls on about 59 days a year.
About 185 frost-free days a year
In half of years the last 32° night comes by April 23 and the first one by October 26. That leaves about 185 frost-free days for gardens, longer than 58% of U.S. towns.
Heating and cooling a home in White Signal
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In White Signal, 80% of that work is heating and 20% 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 White Signal itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at White Signal, NM (1 mi) away. Normals are 30-year averages, not a forecast.
