“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 Moore
Moore gets 10 inches of rain and melted snow a year. May is the wettest month and July the driest. Rain or snow falls on about 48 days a year.
About 119 frost-free days a year
In half of years the last 32° night comes by May 22 and the first one by September 22. That leaves about 119 frost-free days for gardens, shorter than 97% of U.S. towns.
Heating and cooling a home in Moore
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Moore, 96% of that work is heating and 4% 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 Moore itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Arco, ID (8 mi) away. Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
