When to go
January to April gives the most reliable weather and, from roughly January to March, humpback whales passing through the channels to the south-east. December is also popular, especially over the holidays. From June to November rates fall but hurricane risk rises, peaking from about mid-August to mid-October.
Getting there
Nonstop flights reach Providenciales (PLS) from several US hubs, with Miami under two hours away and New York closer to four. From the UK there is no longer a direct service, and the British Airways route stops in Nassau, so expect a long travel day. A US dollar economy keeps costs simple, though resort taxes and service charges add noticeably to quoted room rates.
Where to base yourself
Grace Bay is the default: one long public beach with hotels, villas and restaurants along the road behind it. Pick a central spot if you want to walk to dinner, or the quieter ends towards The Bight or Leeward. The alternative is a private cay. Parrot Cay and Pine Cay are reached by road and boat from Leeward Marina, while Ambergris Cay needs a short flight, and each trades restaurant choice for a beach with almost nobody on it.
How long to stay
Five nights is the comfortable minimum for a first trip, leaving room for a Caicos Cays boat day with a spare day if the wind is up. Four works on an early nonstop from the eastern US. From Europe, or for a private island, a week makes more sense.
