Des Moines Weather in December
United States · early winter in Northern Hemisphere / early summer in Southern Hemisphere
Des Moines in central Iowa has a classic humid continental climate at the heart of tornado alley. The flat prairie surrounding the city means no terrain barriers to weather from any direction — cold Arctic blasts, warm Gulf moisture, and severe spring thunderstorms all arrive unimpeded. The Des Moines and Raccoon Rivers provide some local flooding influence.
Holiday season. Many cities decorate beautifully. Book ahead for December travel.
