Dress in Layers

This is especially important during the spring and autumn, when temperatures can fluctuate significantly throughout the day. Dressing in layers allows you to easily adjust your clothing to stay comfortable, whether it's a mild morning or a chilly evening.

Keeping a water bottle handy and refilling it throughout the day is a simple way to combat the effects of the St. Louis weather.

Be Aware of Severe Weather

St. Louis is prone to severe thunderstorms, tornadoes, and flooding, especially during the spring and summer months.

Prepare for Winter Weather

Winter in St. Louis can bring cold temperatures, snow, and ice. Be sure to dress warmly in layers, wear a hat and gloves, and wear shoes with good traction to prevent slips and falls. If you're driving, make sure your car is properly equipped for winter weather, with good tires, a full tank of gas, and an emergency kit. Keeping an eye on the weather forecast St. Louis will help you prepare for any winter storms that may be on the way.
