You’re going to get wet 100%. Very wet infact. So make sure you’re wearing clothes that aren’t going to bleed colour all over your body (or end up entirely see-through), that they are not you best smart clothes, that your camera and especially your mobile phone is in a waterproof bag (or to be extra safe, just don’t bring it at all or invest in a waterproof disposable one), and that you’re not worried about hair or makeup (because it’s going to be a mess).
Keep your cash and cards tucked somewhere safe in a plastic sachet and don’t even think about carrying unnecessary valuables with you.
Don’t try to escape the gushes of water heading your way, and certainly don’t wear a poncho or carry an umbrella, just relax and enjoy the party getting wet. If you do not then not only are they going to do little to protect you, but you’ll actually make yourself a bigger target.
The best thing to do is just embrace the fact that the moment you step outside your hotel or hostel front door, you’re going to get wet. Besides, since March and April are the hottest and driest time of year in Bangkok & Chiang Mai, the water is actually a welcome relief to cool down!
It’s going to be hot and you’re going to get wet, so best to wear something light, but not too skimpy or see-through. Remember that Thai culture is quite conservative and this is a holy holiday, so avoid wearing thin tank tops or short shorts (especially as a woman; you’ll risk getting unwanted attention), and keep your feet water-friendly with sandals or flip-flops/thongs.
For the most comfort, wear a bathing suit rather than underwear under your outfit. Don’t forget sun protection (sunscreen, sunglasses and a hat), water, and, most importantly, your water weapons!
We’re talking water guns, buckets and bowls all of them are fair game on the streets. You can refill them at free water stations and vendors throughout the old town centres. One thing to remember – Keep your eyes and mouth closed if you’re getting sprayed with moat water in Chiang Mai as its not clean or healthy at all.
