“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 Oark
Oark gets 55 inches of rain and melted snow a year. May is the wettest month and February the driest. Rain or snow falls on about 98 days a year.
About 232 frost-free days a year
In half of years the last 32° night comes by March 25 and the first one by November 10. That leaves about 232 frost-free days for gardens, longer than 86% of U.S. towns.
Heating and cooling a home in Oark
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Oark, 67% of that work is heating and 33% is cooling.
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 Oark itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Ozone, AR (9 mi, snow) and Clarksville 6 Ne, AR (15 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
