Summer season that is March, April & May are hottest. The temperature might go up to 32°C and low around 25°C. The humid is much higher because of the nearby sea.
October to February is a perfect time to visit Pattaya. Even though the weather is not that cold, but definitely it will not be like summer. The average is around 29°C and low at 22°C.
In the sense rainy season and not Songkran or another thing you filthy b**tards. June to September is the rainy season, and it seriously pores a lot. It might be fun at these times to visit Pattaya but, sometimes it might become dangerous as it pours and floods the streets.
