April in korea can be quite cool, so people might need to dress up in warm clothes. However ,in Thailand it is the hottest month of the year, so people wear very light clothes. An important part of Songkran is throwing water at people, while fire is a big part of the Korean festival,as the lanterns have to be lit. The origins of these festivals are also different. Songkran celebrated the end of the harvest, while the Korean Lantern Festival celebrated a Buddhist holiday.
