Rain and snow in Southaven
Southaven gets 56 inches of rain and melted snow a year. April is the wettest month and August the driest. Rain or snow falls on about 100 days a year.
About 244 frost-free days a year

Heating and cooling a home in Southaven
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Southaven, 55% of that work is heating and 45% 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.
