St. Louis in May
Great time to visit
May is peak springtime bliss before summer's swelter arrives. Everyone wants to be outside, so expect company at popular spots. Weather-wise, it doesn't get much better than this in the Lou.
Weather
May serves up some of St. Louis's most pleasant weather before summer's heat arrives. Temperatures sit in that perfect range where you can walk around comfortably all day. Thunderstorms roll through regularly but they're often brief and dramatic rather than day-ruining.

All Months
April through June brings perfect weather and blooming flowers in Forest Park. The humidity hasn't kicked in yet, and outdoor festivals start picking up steam. September and October deliver crisp air and fall colors — ideal for walking the riverfront or exploring neighborhoods on foot.
Summer gets sticky. July and August see temperatures pushing 90°F with humidity that makes it feel worse. But this is when the city comes alive — outdoor concerts, baseball season, and festivals every weekend. Just pack light, breathable clothes and plan indoor activities for the hottest part of the day.
Winter can be brutal with ice storms and temperatures dropping below freezing. January through March sees fewer crowds and lower hotel rates, but many outdoor attractions close or reduce hours.
