Are you serious, what are you on? That is an article over 3.5 years old. I swam in the sea at Jomtien today. The water was very calm and very clear. Followed after by 3 beers watching the sunset. A perfect day and evening, you cant get that in Bangkok its just a busy smelly city and Chaing Mai full of air polution. Pattaya/Jomtien for me every time.
