Most visitors choose Pattaya between November and February, when the weather is at its driest. The rainy season, roughly mid-May to October, has its own appeal: quieter beaches, lower room rates and warm rain that usually passes quickly. It rewards a flexible plan.
What is the rain actually like?
It rarely rains all day. The usual pattern is a bright morning, a heavy shower in the afternoon or evening, then clearer, cooler air. September and October are the wettest months, and some streets flood for an hour or two after a downpour. Month-by-month temperatures and rainfall are in the guide to the best time to visit Pattaya.
Can you still enjoy the beach and Koh Larn?
Yes, on most days. Go early, keep an eye on the sky and swim only inside the marked zones. Ferries to the island keep running in ordinary rain but can be suspended in strong wind, so check the sea state before you leave and do not plan the island for your last day. See the Koh Larn guide.
What can you do when it pours?
- Malls with food courts, cinemas and play areas for children.
- Indoor attractions such as an aquarium or an illusion-art museum.
- A long Thai massage or a spa afternoon.
- A cabaret show in the evening, under cover from door to door.
Ideas with prices and opening hours are in shopping malls in Pattaya, Pattaya with kids, Thai massage and spas and the guide to the cabaret shows.
How should you plan your days?
- Outdoor plans in the morning, indoor plans after lunch.
- Book rooms you can cancel, and leave one spare day for a postponed trip.
- Carry a light rain jacket and sandals that dry fast; an umbrella is little use in a squall.
- Use mosquito repellent at dawn and dusk: mosquitoes are more numerous in the wet months.
Is it worth it?
If you want guaranteed sunshine, come in the cool season. If you prefer space, softer prices and do not mind reshuffling a day, the rainy season is good value. Either way, start with where to stay: a base close to what you want to do matters more when showers cut journeys short.
