July to October is a gamble, and the smart way to play it is to not bet the trip on it. - Author: Somchai Jaidee - Tags: Practicalities, Islands & Beaches The flight from Bangkok to Krabi was cancelled, then rebooked, then cancelled again, over four days, and somewhere in the middle of that I stopped being annoyed about the weather and started noticing that the whole coast was empty. That is the trade. You are not being waited out by a storm. You are being offered a beach that has nobody on it, at a price that reflects it, in weather that might be fine for all of it. Last verified 1 August 2026. ## What is actually happening **The North Indian Ocean basin has a season roughly from April to December,** with activity concentrated between about August and October. Thailand sits right at the western edge of it, which is the worst place to be, because the storms that develop here frequently have nowhere to go but across the country. **The Andaman coast and the Gulf coast are exposed in different ways,** and this distinction matters enormously for planning. The Andaman side, Phuket, Krabi, Khao Lak, takes the western flank and the rainbands. The Gulf side, Hua Hin, Pattaya, [Koh Samui](https://easythailandvisa.com/getting-to-koh-samui-without-flying/), tends to get the more direct hits. **And the South Indian Ocean has its own season,** which affects the Andaman coast from about November into December, at the end of the Thai monsoon rather than the start. **None of this means it rains every day.** It means the probability of disruption rises sharply, and the disruption is clustered rather than spread out, so you will often get five perfect days and then two very bad ones. ## What it does to a trip **Boats stop running.** This is the big one. Speedboats to islands, ferries to [Koh Lipe](https://easythailandvisa.com/koh-lipe-and-satun-southern-islands/) and [Koh Tao](https://easythailandvisa.com/koh-tao-scuba-diving-course/), the small boats to Koh Lipe's neighbours, the ones from Pak Bara. A cancelled boat with a once-a-day schedule means a night on an island, and a cancelled boat with a twice-a-week schedule means a longer one. **Flights get cancelled and diverted,** and this is the most disruptive thing in the whole system, because a [domestic flight](https://easythailandvisa.com/domestic-flights-in-thailand-booking/) out of Phuket or Krabi or Surat Thani is usually the last leg of a long journey home. **Temples and national parks close,** partially or entirely, for safety. Khao Sok, Erawan, Khao Yai and Doi Inthanon all have sections that shut when the conditions demand it, and it is not always published in advance. **Flash flooding happens,** mostly in towns and mostly with little warning, and a great deal of the danger is a tourist standing in water where they did not expect it rather than anything dramatic. **And the seas are simply rougher,** which ends the small-boat day trips that people booked the trip for. ## What it does not do **It does not rain constantly.** The monsoon in Thailand is dramatic rather than drizzly, and a morning storm can be followed by an entirely clear afternoon. **It is not dangerous in the way people imagine,** provided you do the obvious things. The genuine risks are flash flooding in streams, being on a boat in bad conditions, and driving on flooded roads. All three are avoidable by following closures. **And it is not uniformly bad across the country.** The north, the northeast and the inland are largely unaffected, and the seasons are different there. ## How to plan around it **Go to the Gulf coast in the high season and the Andaman in the shoulder,** and if you have a fixed preference, understand the odds before you book rather than after. **Build in a buffer at the end.** Not at the start. A delayed departure at the end costs you a day at the end; a delayed arrival at the start costs you a day you were never going to use. **Book the return flight and the international connection separately,** so that a cancelled domestic leg does not take your international flight with it. **And do not book a multi-day tour with a non-refundable price in the storm months,** unless the operator's cancellation terms are genuinely good, because the operator's risk and yours are not the same and only one of you is exposed to it. ## The insurance question, which is specific **Most travel insurance policies exclude travel to an area under a government travel advisory, and some suspend cover for weather events named in a specific list.** Read the policy's natural disaster and advisory clauses, not just the exclusions summary. **Weather cancellation is a different question from weather damage,** and a policy can cover you for a trip you cannot take and not cover you for a boat you cannot board. **And check whether the cover extends to activities cancelled by a third party,** which is exactly what a cancelled speedboat is. ## How to watch it **Use an official source and not a weather app that shows a generic map.** The Thai Meteorological Department publishes warnings, and the Department of Disaster Prevention and Management issues evacuation orders, and both are the thing to actually read. **Learn the local vocabulary of a warning before you need it,** because a warning in Thai with no English tells you nothing useful in the twenty minutes it matters. **And keep a change of cash, a power bank, and a plan for being somewhere without air conditioning**, because the power goes out in a storm and a hotel with no power in a hot coastal town is a genuinely different experience from the one you paid for. ## My honest view **The Gulf coast in high season is a mistake of scheduling, not of geography.** There is no version of July on the Gulf coast that is reliably good, and no amount of research changes that. **The Andaman coast in low season is the actual opportunity.** Prices fall by a factor that is genuinely significant, the crowd falls by more, and the weather is worse with a high enough variance that you may well get lucky. **And the north is a completely different season,** with a cool dry winter and a genuinely different country, which is why so much of the advice about this period amounts to telling people to go somewhere else. **More on this** - [A Sea Snake in Thailand Is Almost Certainly Not Going to](https://easythailandvisa.com/jellyfish-and-sea-snakes-in-thailand/) - [The Jet Ski Damage Scam Is a Whole Industry and Knowing It](https://easythailandvisa.com/jet-ski-and-beach-club-scams-in-thailand/) - [How to Book a Longtail Boat Without Paying Twice](https://easythailandvisa.com/longtail-boat-island-trip-booking/)
