Krabi 4 Islands Tours

Tides, weather and timing

When to visit the 4 Islands

The day’s sea conditions and tide matter as much as the date on your calendar.

When to visit the 4 Islands

November to March: the listed preferred season

The classic longtail and private-tour FAQs describe November–March as the preferred period, while the shared speedboat FAQ highlights November–February. Treat these as seasonal expectations rather than a promise of calm seas or clear skies. Exact conditions still determine the route.

Outside the preferred season

Keep room in your travel plans for rescheduling and check the local forecast with the operator close to departure. Rain alone does not necessarily cancel the shared speedboat; its published policy distinguishes rain from unsafe waves. Do not assume the same operating decision applies to every boat.

Tide matters on every travel date

Talay Waek is a changing sandbar, not a permanent footpath. Ask whether your selected departure is expected to reach it near low tide, but never treat a forecast or a private booking as a guarantee that you can cross. Follow the crew’s instructions on the day.

Cancellation is different from choosing not to travel

The four classic listings currently say cancellation or moving your booking is free until 24 hours before the start; late cancellations and no-shows are non-refundable. Their operator-cancellation policy offers a new date or a refund. Read the live terms on your selected tour before booking; personal concern about rain is not itself confirmation that the operator has cancelled.

Questions about when to visit the 4 islands

Can I walk across the sandbar at Tup Island?+

Only when the tide is low enough. At higher tide the connecting sandbar can be under water. Choose the boat for its whole itinerary; a dry sandbar crossing cannot be guaranteed.

Does rain automatically cancel a tour?+

Not necessarily. The shared speedboat FAQ says rain alone does not automatically cancel it, while unsafe waves can. The operator makes the decision for the actual boat and date.
