Learn moreA Genuine Four-Season, Humid Continental Climate
St. Louis's climate delivers a real, distinct experience across all four seasons: hot, humid summers (average July daytime high approximately 89°F, with frequent thunderstorms); crisp falls; cold winters (average January overnight low approximately 24°F); and a genuine spring. This is a defining, real amenity for movers who specifically want four distinct seasons rather than a warm-winter or warm-year-round climate, though the real, hot summer highs are worth budgeting for directly (cooling costs, humidity tolerance).
Moderate Snowfall, But Genuinely Hot Summers
St. Louis averages approximately 16 inches of snowfall per year against roughly 43 inches of total annual precipitation -- a real, moderate winter-snowfall total relative to several snowier Midwest and Great Lakes-adjacent markets covered elsewhere in this project. Movers coming from milder-summer regions should budget realistically for St. Louis's genuinely hot, humid summer stretch (average July high approximately 89°F) rather than assuming a moderate snowfall total implies a moderate climate overall.
Spring and Early Summer Carry Real, Elevated Severe-Weather Risk
As detailed in full on the flood-hurricane-risk topic page, St. Louis's real, elevated tornado risk concentrates in the spring and early-summer window, tied directly to the region's position within the broader Midwest severe-weather corridor -- the dated, destructive May 16, 2025 EF3 tornado struck during this period.
A Real Amenity for Movers Who Specifically Want Four Distinct Seasons
