It’s water festival time in Thailand where many are marking the country’s traditional New Year, splashing each other with colorful water guns and buckets in an often raucous celebration that draws thousands of people, even as this year the Southeast Asian nation marks record-high temperatures causing concern.

The festival, known as Songkran in Thailand, is a three-day shindig that starts Saturday and informally extends for a whole week, allowing people to travel for family celebrations. The holiday is also celebrated under different names in neighboring Myanmar, Cambodia and Laos, which like Thailand have populations that are predominantly Theravada Buddhist.
