Traveller notes on Fort Lauderdale in September
Notes from nearby Miami (39 km away)
Fort Lauderdale doesn't have its own notes for September yet — these are about Miami, close enough to share the season.
Miami's forum calls September hot and heavily humid — 90s°F highs, humidity often 90%+ — and one of the wettest months of the year, typically sunny mornings giving way to a fast-moving afternoon downpour from around 3pm. Regulars' standard advice is to front-load sightseeing and beach time into the morning, and to keep an eye on the forecast given September sits near the peak of hurricane season.
