Actually, the rainy season in Pattaya is not the same as in the other provinces of Thailand. The heaviest rainfall here tends to be at the beginning and end of the season with some rainy days in between, but often you have many days with perfect weather and sunshine. - Pattaya and Hua Hin are the cities with most sunshine hours per year in Thailand!
