Spring and fall see mild conditions, with temperatures averaging in the mid to high 60s in April and October.
Crowd InformationSt. Louis can get pretty crowded during the summer, especially for baseball season from April through October, when the St. Louis Cardinals draw more than three million attendees each year. Labor Day weekend is also popular, with two major events drawing visitors: the Big Muddy Blues Festival and the Japanese Festival at the Missouri Botanical Garden. The city also celebrates several other major festivals, including Mardi Gras in February or March (depending on the year), the St. Louis Jazz & Heritage Festival in June, and the St. Louis Art Fair in September.
Closure InformationHotels, shops, and restaurants remain open throughout the year.
When to SaveAlthough hotel rates remain fairly standard throughout the year, hotel prices may rise during major conventions or Cardinal home games. Discounts and packages are available through the St. Louis Convention and Visitors Commission. Visitors can also save by going to one of the many free attractions or institutions located throughout the city, including the St. Louis Zoo, the St. Louis Art Museum, the Missouri History Museum, and the Anheuser-Busch Brewery Tour.
When to BookSt. Louis is a reasonably priced destination year-round. Visitors with flexible travel plans can take advantage of low last-minute airfares. However, those with a set schedule should book flights at least three weeks in advance to obtain lower prices and ensure availability, especially for travel during the summer high season. Last-minute lodging is available throughout the year, but book at least two months in advance to reserve a downtown room during major conventions, Mardi Gras, or Cardinals' home games.
