Pattaya weather has three key seasons: Hot (March-May), Rainy (June-October) and Cool (November-February). It is warm and humid year-round, with little difference between the hottest and coolest months. Average year round temperatures are around 27°C.
The months with the most rain are July, August and September. Pattaya’s coastal location brings sea breezes and the rain tends to come in short and heavy bursts rather than prolonged over days. No matter when you come, you'll have a good time. Lightweight casual clothing is recommended.
