About Wyandotte County Weather
Wyandotte's Balanced Temperate Climate
Wyandotte County's 53.6°F average annual temperature places it squarely in the middle of America's temperate zones. This humid continental climate experiences wider temperature swings than coastal counties, though it remains warmer than many northern Plains regions.
Cooler and Wetter Than the Kansas Average
The county ranks slightly cooler than the Kansas state average of 54.8°F. However, it is one of the wettest spots in the state, receiving 10 inches more annual precipitation than the 30.3-inch state average.
Regional Climate Stability in the Kansas City Metro
Wyandotte mirrors the climate of neighboring Johnson County, benefiting from the moisture-rich air of the eastern Kansas border. With 40.5 inches of rain annually, it provides a much greener landscape than the more arid counties located in western Kansas.
Sweltering Summers and Brisk Winters
Extreme heat is a staple of the local summer, with 34 days a year hitting 90°F or higher. Winter brings a sharp contrast, delivering an average of 17.4 inches of snow and a chilly January mean of 28.0°F.
Managing Humidity and Seasonal Extremes
Residents should prioritize high-efficiency cooling to navigate the month of July, which averages a warm 77.3°F. Winter maintenance is equally vital, as the 30.8°F winter average requires reliable heating and seasonal prep for the 17.4 inches of annual snowfall.
