Weather and Seasons in Key West
Spring
Spring is often considered a shoulder season here — the weather is warming up, tour prices haven’t hit their peak yet, and the destination feels noticeably less crowded than it will in a couple of months.
Summer
If Key West has a true high season, it’s summer — everything is open, the energy is at its peak, and it’s the most popular time for families to visit thanks to school holidays.
Autumn
Many repeat visitors consider fall an underrated time to be in Key West — the crowds from summer have mostly cleared out, but the weather is often still cooperative for outdoor plans.
Winter
Winter is typically the slowest season in Key West, which can mean better rates on tours and accommodations, though some outdoor attractions may run on reduced hours. It’s a reasonable trade-off for travelers who prioritize lower costs and thinner crowds over ideal weather.
