13 April – 19 April 2017
Officially Songkraan in Thailand is from 13 – 15 April. However in Pattaya there some extra days :
Naklua (North of Pattaya) 18 April
Pattaya : 19 April
So more ore less Songkran in Pattaya is from 13 – 19 April.
Especially the last two days are like a “water war” on the streets.
