What happens if your Phuket tour is cancelled because of bad weather

A cancelled sea tour comes down to three questions: who calls it off, what you get back, and how early you had to act. The answers sit in each operator’s terms, and many operators publish less than you would hope. Below is what Phuket Tour, Tisland and four evening shows publish, checked on 3 November 2026, with the gaps marked. Phuket Tour is the operator our site works with, so read its terms as one operator’s terms, not as a market rule.

Who decides whether the boat goes out

A TMD warning does not close the sea by itself, and its wording changes between advisories. On 21 May 2026 TMD advised small boats in the upper Andaman Sea to keep ashore, while the advisory of 3 November speaks only of ships and thundershowers. The operator decides what to do with it. A bad forecast is also not always a cancellation: Phuket Tour’s FAQ says tours are cancelled quite rarely and rain on its own is not a reason.

Park closures are a calendar matter, not a weather call. The Similan and Surin islands are closed for part of the year, so no operator should sell you a day there in that window. The dates are on our Similan Islands page.

Sea tours: what Phuket Tour and Tisland publish

Both operators’ pages were opened on 3 November 2026. Tisland’s cancel and refund page carries no date. Tisland’s July 2026 guide adds that a good operator warns you of a cancellation in advance rather than on the day and that you should confirm the status with your operator the day before.

Evening shows: what the venues say

Prices, days and children’s rules for the same four shows are in Phuket evening shows compared.

If the operator cancels and if you cancel

• The authorities ban sea departures, or the operator calls the tour off. Phuket Tour offers a new date, or a refund if the new time does not suit you. Tisland’s page has no rule for this, so ask before paying
• The sea is open but you do not want to go. At Phuket Tour you get a refund only if you cancel at least one day before the tour. A storm is refunded without restrictions, but the page does not say whether a forecast alone counts, so ask how they define it
• You are ill. Phuket Tour refunds without restrictions with confirmation from a medical institution. Tisland refunds in full against a certificate from a Phuket hospital delivered by 3 pm on the day of the excursion, with exceptions listed on its page, including the Similan Islands
• You do not turn up. None of the operators we read publishes a no-show rule for sea tours. Carnival Magic’s FAQ says late arrivals get no refund, full or partial. Assume a no-show is not refunded

Insurance

Phuket Tour says insurance is included in the price and that a Thai operator’s insurance covers every excursion. Its pages do not publish the policy, so ask for the insurer’s name and what it pays for. We have not reviewed any travel insurer’s wording: whether your own policy covers a tour cancelled for weather depends on its text.

Red flags on the beach

A red flag means stay out of the water. TAT’s 2018 guidance lists red as no swimming, yellow as medium risk and green as calm. How rip currents work and how to get out of one is in our guide to the red flag on a Phuket beach. We found no operator rule that treats a red flag at a snorkel stop as a reason for a refund, so ask the captain what changes on the route. For the October 2026 floods and the rain that followed, see Phuket flooding.

What to ask before you pay

• Who decides to cancel for weather: a TMD warning, an authority ban or the captain?
• If the tour is cancelled, do I get a new date or a refund, and can I refuse the new date and take the money?
• How many days until the money is back, and to which card?
• Until what time the day before can I cancel myself, and does a bad forecast with an open sea count?
• How and when will you tell me about a cancellation: the evening before or at the pier?
• Are park fees, transfer and lunch refunded too?
• What happens if I am ill or late?
• Is there a plan B in a sheltered bay, and does the price stay the same?
• Is all of this in the voucher, the contract or a chat message I can keep?
• Which insurer covers the excursion, and what does the policy pay for?

If your tour is cancelled

1. Ask the operator to confirm the cancellation in a message and name the reason: a TMD warning, an authority ban or the captain’s decision
2. Choose between a new date and a refund. Phuket Tour’s FAQ offers both for a sea ban, so confirm the same applies to your reason
3. Check a new date against your flights and your non-refundable bookings, such as evening shows
4. Keep the voucher and the chat until the money arrives: we found no refund deadline on the operators’ pages

What we did not find

• The text of Phuket Tour’s contract: the payment page refers to it, but we found no public copy
• A no-show rule and a refund deadline on the pages of Phuket Tour and Tisland
• A weather clause on Tisland’s cancel and refund page
• A published order from the Phuket Marine Office or the provincial administration for the days around 3 November 2026: such notices can appear on the offices’ social media, which we did not check
• Public weather terms from other large operators: our search found none for Love Andaman
