Cheap Flights from Bangkok

Songkran will be celebrated from the middle of April and often runs for roughly a week unofficially in parts of Bangkok and Pattaya. Thai people know the way to party and celebrate their own New Year, Chinese New Year and the Western New Year. Of the 3, Songkran is the craziest.
Depending on who you ask, Songkran is the best or the worst time of year to be on holiday. The real reason for that is water. Historically, Songkran is a water holiday and celebrated by sprinkling water on other folks. In holiday maker areas of Bangkok like Pattaya and Phuket, the sprinkling has escalated to launch hoses, water tube blasters and super-soakers. Drunken tourists and neighbors in Pattaya and on Khaosan Road in Bangkok take this holiday as a time to get totally funny and drench one another in water.
In addition, a white paste made of flour or talcum powder is smeared on oblivious people's faces. If you're in a tourist area or perhaps in an upcountry village during Songkran, you should expect to get wet. The more touristy the area, the wetter you'll get. Being drenched and then going into an air conditioned bar or restaurant can be really uncomfortable and can lead to an unpleasant cold. There's also the chance of infection as the water is not necessarily clean.
It's not that I am making an attempt to throw a damper on a New Year party but I'm just attempting to let folk know that they can expect to see plenty of drunken tourists getting soaking wet in during this holiday time. You may have plenty of fun, but you can see tourists at their unreserved worst.
Getting back to the genuine meaning of Songkran, it's a time to go to the church to hope and give food to the friars. It's also a time to clean the Buddha pictures at their household shrines and at the priori's with water and a nice perfume. This is also a standard time to make resolutions to do good deeds and desist from malignant and even a time to wash the house. In short, out with the old and in with the new. Unfortunately, it's also the worst time of the year for road accidents and deaths on the road. Many expats who live in Thailand leave the country or head north to quieter Songkran parties and leave the tourist areas to the tourists. Personally, I schedule my trips so I am miles away from Thailand during New Years. As are most other stuff in Thailand, it is up to you whether you need to experience Songkran.
I'd advise to seeing it one or more times and then you can define for yourself if you would like to return to do it again. If you go, use caution on the slick roads and boozed up drivers and be sure to bring masses of zip-lock bags to keep your stuff dry.
