“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 Oasis
Oasis gets 8 inches of rain and melted snow a year. April is the wettest month and July the driest. Rain or snow falls on about 53 days a year.
About 137 frost-free days a year
In half of years the last 32° night comes by May 14 and the first one by September 30. That leaves about 137 frost-free days for gardens, shorter than 91% of U.S. towns.
Heating and cooling a home in Oasis
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Oasis, 87% of that work is heating and 13% 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.
