Traveller notes on Shoal Bay in September

Notes from nearby The Valley (7 km away)

Shoal Bay doesn't have its own notes for September yet — these are about The Valley, close enough to share the season.

Anguilla's forum doesn't hide that September sits in peak hurricane season - hot, humid days with a real chance of passing showers or a grey, rainy stretch, and many hotels and higher-end restaurants close for the season regardless of the day-to-day forecast. That said, several posters put the odds of a clear, sunny day at roughly 80%, and one traveler's late-September week was described as brilliantly clear and hot throughout. The trade-off that comes up again and again: genuinely quiet beaches and warm, calm water in exchange for accepting real storm risk and limited services.

Other months in Shoal Bay

Anguilla-forum threads on March weather split on the wind: one visitor's early-March week ran extremely windy by day, choppy enough that Shoal Bay East got skipped entirely for calmer water elsewhere on the island, while a longtime regular calls the first week of March close to magic, just enough breeze to keep the mosquitoes and no-see-ums away without ruining the beach. Both camps agree on the temperature read - hot but rarely humid, one of the more comfortable stretches of the year to be outside all day. The general consensus lands on March as a strong pick overall despite the wind variability, with the caveat that a windy day can turn the open-water beaches choppier than photos of Anguilla's famously calm bays suggest. The record backs the wind read directly: 28.2C days feeling like 31C, 24.6C nights, 22mm across 8.4 days, a 26.1C sea, 76 percent humidity, 11.1 hours of sun and wind averaging nearly 30 km/h - genuinely breezy by the numbers, exactly as the forum describes.
