3A – Warm Humid

Sunflower County, Mississippi is located within the Warm Humid climate zone, which also has the designation of #3A. The US Department of Energy has split the United States into eight zones to help in creating optimal building practices to achieve the most energy savings within homes.

A warm-humid climate is defined as a region that receives more than 20 inches (50 cm) of annual precipitation and where a thermometer can reach either 67 °F for 3,000 hours or 73 °F for 1,500 hours during the warmest six consecutive months of the year through evaporative cooling.
