Best Time to Fly to St Louis

Peak Season

Summers in St. Louis are hot and humid, but this is also the best time to visit if you want to take part in the riverfront activities. St. Louis is a big baseball town, and the St. Louis Cardinals draw thousands of fans each year. If you’re planning to visit St. Louis during the spring and summer seasons, book flights early and make accommodations ahead of time. The city gets full fast.

Off Season

St. Louis is prone to long, cold winters.  The city all but shuts down during the wintertime and while many tourist attractions are open to the public, none of the outside activities are much fun in the snow. However, if you’re heading to St. Louis for some football time or to explore the excellent museums, you’re likely to find a cheap flight to St. Louis in the winter.

Overview

Visitors to St. Louis are greeted by the Gateway Arch, standing 630-feet high and constructed completely of stainless steel. Historically, St. Louis was a center for travelers from all over the world who were heading westward in search of new opportunities and a new life. In the early 1900’s, the ‘Show Me State’ of Missouri hosted the World’s Fair and as a result, witnessed the beginning of the city’s innovation and technology boom.

Today the city is blanketed with history, but also rich in entertainment. Travelers visit St. Louis every summer for one of the best Independence Day celebrations in the nation. Take a tour around downtown St. Louis and visit the Anheuser Busch Brewery and Busch Stadium, home of MLB St. Louis Cardinals.
