Sioux City Weather in May
United States · late spring in Northern Hemisphere
Sioux City at the meeting of Iowa, Nebraska, and South Dakota on the Missouri River has a harsh continental climate at the edge of the Great Plains. Cold Arctic air arrives with little warning and blizzards can be intense. The Missouri River valley provides some shelter but also contributes to flooding risk and valley fog.
One of the most popular travel months worldwide for good reason.
