“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 Corona
Corona 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 54 days a year.
About 172 frost-free days a year
In half of years the last 32° night comes by April 29 and the first one by October 20. That leaves about 172 frost-free days for gardens, shorter than 58% of U.S. towns.
Heating and cooling a home in Corona
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Corona, 88% of that work is heating and 12% 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 Corona 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 Corona averaged 1.9° warmer than the 1900s. The biggest change is in March (+3.2°). The shift is larger than in 90% of U.S. towns.

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 35° to 49°. July is the most reliable, staying within 7°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Corona itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Corona 10sw, NM (9 mi) away. Normals are 30-year averages, not a forecast.
