Saint Louis Weather in August
United States · late summer in Northern 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.
Hot in many cities. Beach and outdoor destinations are at their peak.
