September is the month nobody writes a brochure about. It's the hottest stretch of the year, it sits in the middle of hurricane season, and a fair number of restaurants take their annual break. It is also the month when this island is most itself, and the month when a week here costs a fraction of what it costs in February.
Here's the honest accounting.
What you actually get
Empty beaches. Not "quieter" — empty. The cruise schedule thins out, the winter crowd is gone, and you can pull up to a beach on a Tuesday and be the only car. The water is at its warmest of the year, well into the eighties, and the hills are green from summer rain rather than the dusty brown they go by March.
Rates drop hard across the island, ours included. If your budget is the thing standing between you and a trip, this is the month that solves it.
What you're risking
Hurricane season runs June through November, and September is its statistical peak. That doesn't mean a storm — most September weeks here are ordinary hot, bright weeks with an afternoon downpour that clears in twenty minutes. It means the chance is real, and you should plan like an adult about it: buy travel insurance that covers weather cancellation, watch the forecast in the week before you fly, and understand your airline's change policy before you need it.
The other thing to know is that some restaurants and a few businesses close for a few weeks in September. Check before you build an evening around a specific place.
Who it's right for
It's right for people who came for water and quiet, who don't need a packed calendar, and who can absorb a schedule change if weather forces one. Divers and snorkelers do well — warm, calm water and nobody in it. Families tied to a school calendar mostly can't use it, which is exactly why it's empty.
It's wrong for anyone who needs certainty, or who'd be genuinely wrecked by a rained-out day.
If you go
Plan around mornings — the heat and the clouds both build in the afternoon, so swim early and take the middle of the day slow. Somewhere with a kitchen and shade earns its keep in September; both our places have both, and if the sky opens for an hour you want to be somewhere you don't mind being stuck. The Sapphire Beach condo puts you on the sand; the Mahogany Seaview villa puts you up in the breeze with a long view of exactly the kind of sky in the photo above.
For a warmer, safer shoulder month with most of the same emptiness, June is the one we'd point you to first. Off-season weeks run 15% off open dates — current availability is on the deals page.
