About Davis County Weather
Approaching the National Temperature Median
Davis County averages 51.2°F annually, bringing it closer to the national median than most of its northern peers. The county receives 39.1 inches of annual precipitation, which is significantly higher than many more arid regions in the Western U.S. This climate is defined by its humid, productive summers and moderately cold winters.
One of Iowa's Warmest Counties
Davis County's 51.2°F average temperature is significantly higher than the Iowa state average of 48.0°F. It also receives about 3 inches more rain annually than the state average of 36.1 inches. This makes it one of the warmer and wetter pockets in the southern Iowa landscape.
Consistent Warmth Across the Southern Border
Davis County shares a similar climate profile with its neighbor Decatur County, which averages 50.9°F. Both counties enjoy warmer winters and more precipitation than northern Iowa counties like Emmet or Dickinson. This southern positioning allows for a slightly longer growing season and fewer extreme cold snaps than the rest of the state.
Frequent Heat and Moderate Snow
The county experiences 22 days of extreme heat annually where temperatures top 90°F, peaking with a 75.9°F July average. Winter brings 24.2 inches of annual snowfall and a January average of 23.4°F. These numbers reflect a region where summer humidity and winter slush are both regular parts of life.
Budget for Both Cooling and Plowing
With over three weeks of 90-degree days, reliable air conditioning is a necessity for Davis County residents. Homeowners should also maintain snow removal equipment to manage the 24.2 inches of annual snowfall. The higher-than-average precipitation means moisture-sealed basements and effective gutter systems are critical for property maintenance.
