Saint Louis Weather in October
United States · mid-fall in Northern Hemisphere / mid-spring in Southern Hemisphere
St. Louis at the confluence of the Missouri and Mississippi Rivers has one of America's most oppressive summer climates. The rivers converge here creating maximum humidity, and the city sits in a bowl that traps heat. The 2012 heat wave killed many here, and the Gateway Arch's stainless steel surface is so thermally conductive it can be felt at distance on hot days.
Foliage season in temperate cities. Often the best month to visit Europe.
