Is September Right for You?
Weigh the advantages and considerations before booking
- + September lands between summer crowds and winter yacht season. Empty anchorages in the Tobago Cays sit waiting. February can't match this space. Book now.
- + Months of Caribbean sun push the water to 29°C (84°F). Snorkel for hours. Skip the rash vest. Stay in.
- + Hotel rates cards drop 30-40% after peak. That overwater villa in the Grenadines flips from aspirational to achievable. Same view, less pain.
- + Local food peaks in September. Fresh breadfruit, golden apple, and the final mango flush arrive before October rains. Eat fast.
- − Hurricane season is still on. Direct hits stay rare here. Keep flexible plans. Buy weather cover.
- − Smaller outer-island resorts shutter for annual maintenance in September. Your room list shrinks. Book early.
- − Humidity locks at 70%. Everything feels damp. Passport pages curl. Cotton hangs on yacht railings for days. Pack synthetics.

Best Activities in September
Top things to do during your visit
September's flat morning seas and clear sightlines turn turtle time into a private show. Green turtles graze the seagrass beds steps from your dinghy. The five uninhabited cays are boat-only, and you will own the marine park before 10 AM. Water tops 29°C (84°F); you can float for hours without a chill.
Morning clouds in September gift you a cool start on the 1,234 m (4,049 ft) climb. Set off at 6 AM. You top out before midday clouds seal the view. Summer's dry spell firms the rainforest and lava trail, so the 3.5-hour ascent stays sure-footed, unlike wet-season slime.
September fires the traditional start of Bequia's whaling season. Actual hunts are almost history. The Paget Farm museum keeps longer hours. Walk Hamilton's yard in Lower Bay at dawn and meet fourth-generation builders. They will walk you around the 28-foot (8.5 m) double-ended whale boats that slid off these beaches for 150 years.
September strips the crowds from Mustique. The island feels leased to you. Basil's Bar fires up lobster BBQs on Wednesdays, and locals show. Macaroni Beach hosts more turtles than tourists. The 45-minute hop from Bequia rides easiest in September's lighter trades. Day passes unlock the same sand European royalty uses.
Kingstown Market on Saturday morning is a produce PhD. September piles christophene, golden apples, and the year's finest breadfruit onto tables. Nearby home kitchens run informal classes. Learn oil-down, the national one-pot, and breadfruit chips. Nutmeg, fresh turmeric, and soursop perfume the air.
September Events & Festivals
What's happening during your visit
This informal weekend throws every float-worthy hull into racing madness. Port Elizabeth harbor fills with 60-foot (18 m) catamarans and 20-foot (6 m) converted fishing boats. Beach BBQs and rum shop parties run past midnight. You watch generations of sail-tuning skills passed on the spot.
