How is the weather in Pattaya during September?
Yes it will rain in Pattaya during this time period. However, the rain usually stops in an hour or so and the sun comes out nice and bright again. Often the rain falls at night when you are asleep. Some minor flooding in some areas until the drains can handle deluge. One good thing about being in Pattaya during September is that some hotels have good deals on rooms. For questions about “companionship” you will get the most honest answers when you ask those questions from an expat or an experienced traveler in person after you get to Pattaya.
