Trodde det har något med sydvästlig vind att göra, Pat-aya. Hittade detta på Google:
The name “Pattaya” was originated from the march of Phraya Tak (later known as King Taksin the Great) and his followers from Ayutthaya Province to Chanthaburi Province just before the fall of the Ayutthaya Kingdom to the Burmese invaders in 1767.
When Phraya Tak’s army arrived in the vicinity of what is Pattaya today, he encountered the troops of Nai Klom who tried to intercept him. When the two leaders met face to face, Nai Klom was awed by Phraya Tak’s dignified manner and his army’s strict discipline, thereby surrendering without a fight. The place where the two armies confronted each other was later called Thap Phraya, which means the Army of the Phraya. This was later changed to Phatthaya, which happens to mean the wind blowing from the southwest to the northeast at the beginning of the rainy season. Today the spelling of the name has been simplified to Pattaya.
