The heat in Thailand intensifies once the month of April comes. People of old were wise enough to initiate the Songkran festival to cool themselves off from the heat and celebrate it as the Thai New Year. In the central region, the festival is usually held on the 13th, l4th and 15th of April while in the East there is a difference as the water throwing activities commence on the l6th or 17th, 18th or 19th known as "Wan Lai" (Flowing Day).

Pattaya City holds its Wan Lai festival annually on April 19th with activities such as water pouring for the elders, processions and the fun of dowsing and another with water, a time for Thais and foreigners alike.
