Traveller notes on The Valley in August

Other months in The Valley

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.

Forum posters consistently name March as one of the most desirable months weather-wise - hot but rarely humid, with little rain and noticeably lower mosquito and no-see-um activity thanks to steadier wind. That same wind can be strong enough to rough up the surf at popular spots like Meads Bay, though posters note calmer alternatives sit just a 5-15 minute drive away among the island's roughly three dozen beaches. Crowds run lighter than the December-February peak while restaurants and activities (stand-up paddleboarding, tennis, golf, nature tours) stay fully open, making March a popular pick for travelers escaping northern winters without the highest-season prices or crowds.

Recurring seasonal events, natural spectacles, closures and holidays — curated and sourced.

  • Hazard

    Sargassum season

    1 May – 30 Sep · usually

    Anguilla is hit less hard than islands further south, but weed still lands on the south and northeast coasts most years - Savannah Bay, Sandy Hill Bay and Shoal Bay East are the names locals watch. How bad a season gets varies week to week rather than by the month. Source ↗

  • Hazard

    Hurricane season

    1 Jun – 30 Nov

    Irma made a direct Category 5 hit in September 2017, doing an estimated US$320 million in damage and knocking out the House of Assembly and the ferry terminal at Blowing Point for months. Most seasons pass without a direct strike, but the island is low and flat with nowhere to hide from one that does. Source ↗

  • Festival

    Anguilla Summer Festival

    24 Jul – 9 Aug · usuallyCarnivalCrowdedBook early

    Anguilla's carnival: two weeks of calypso finals, pageants and the Parade of Troupes building to J'ouvert before dawn and a string of boat races that double as the island's national sport. The Valley and Sandy Ground carry most of it. Source ↗

  • Closure

    Off-season hotel closures

    16 Aug – 15 Oct · usually

    Several of the island's biggest names close for repairs and staff leave between mid-August and mid-October, Cap Juluca and the Four Seasons among them. Rates at what stays open are the lowest of the year, and villas and a handful of restaurants keep going regardless. Source ↗
