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 during the spring and summer seasons, book flights to St. Louis early and reserve accommodation 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.

St Louis 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 centre for travellers 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. Travellers take flights to St. Louis every summer for one of the best Independence Day celebrations in the nation. Take a tour around the city centre and visit the Anheuser Busch Brewery and Busch Stadium, home of MLB St. Louis Cardinals.

St. Louis climate

St Louis has moderate, seasonal weather, but storms can occur at any time of the year. July and August are the hottest and most humid months of the year, and January and February are cold, usually with snow. Winter temperatures range from below 0 to 13 degrees C, while summers have daily temperatures of between 14 to 32 degrees C.

Getting around St. Louis

The local transport connects the central regions and is a great way to travel throughout the city. It’s possible to access the majority of St. Louis tourist attractions via the public transport, so a car isn’t necessary. There are shuttle buses that will transport travellers from some attractions to the nearest station. Travellers can pick up a shuttle service map at any of the stations, or at first attraction. Bus services are part of the same network, but extend throughout St. Louis counties.

Renting a car is also an option. St. Louis is a very easy city to navigate and parking is abundant throughout the city. However, if you plan to drive to the suburbs, the navigation might become a little tricky. Make sure to check with your hotel or a local before hitting the motorway in your rental car.

Taxi stands are located at most major hotels around the city and at common tourist attractions. Cabs can also be reserved ahead of time.

Getting from the Airport to the City

Lambert–St. Louis International Airport (STL) is located around 10 miles (16 km) northwest of downtown St. Louis.

What is good to know if travelling to St. Louis?

  • Celebrate Independence Day in style with a flight to St. Louis. Grab a blanket and a couple of chairs and head down to the riverfront for 4th of July. Grab a spot underneath the Arch and enjoy the spectacle. From people watching, to concerts and outdoor vendors and markets, there is much to do to celebrate America’s birthday. And of course, an amazing fireworks display happens on the riverfront.
  • St. Louis’ Soulard Market Place is home to the best outdoor markets in the city, and also one of the best Mardi Gras parties in the Midwest.
  • The Butterfly Garden in St. Louis’ suburb, Chesterfield, is a must-see for travellers of any age. Located in Faust Park about 30 minutes west of St. Louis City, the Butterfly Garden is a delight for everyone.
  • You don’t have to be a baseball fan to appreciate Busch Stadium. Take a tour of the Stadium or take in a game.
  • Beer lovers know St. Louis as the home of Anheuser-Busch. Brewed right in the city centre, the Anheuser-Busch Brewery offers daily tours, and of course, beer tastings. 

St. Louis airport overview

Lambert-St Louis International Airport, or Lamberts as it’s affectionately known, is located 17km (10 miles) northwest of the city of St Louis, Missouri, and is in close proximity to connecting interstate highways. With four long runways and more than 12 million passengers per year, Lamberts is the state’s busiest airport; nonstop flights to Lambert-St Louis International Airport arrive from 88 domestic and international hubs.

Lambert-St Louis has a certain historical pedigree, too. It served as a balloon-launching base in the 19th century and was later visited by the Wright Brothers on one of their early flights. In 1910, Theodore Roosevelt took a flight from here, becoming the first US President to fly, and a few years later the first experimental parachute jump took place over the airfield.

A new construction project – launched in spring 2011 – is set to improve passenger services, boost airport operations and offer good views of the establishment. Terminal 1 is already an architectural spectacle, with exciting LED lighting that may be viewed from the interior and exterior of the building, as well as new flooring, ticket counters, signs, security checkpoints and an atrium, all of which have resulted in a completely new and attractive look for Lambert-St Louis International Airport.
