When to go

Best time to visit Miami

Miami is a yearround destination, but conditions shift with cold fronts and hurricane season.

Best overall window

March to May and October to November

Comfortable weather and improving water. Virginia Key averages rise from about 23°C in March to about 26°C in May, then cool to about 26°C in November.

Outside that window

January can be the windiest month for small boats, while July and August are hottest and sit in peak storm season.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
