"The recent El Nino weather pattern that is responsible for the recent  flooding in Australia, has created higher than normal sea water  temperatures in 2010 & 2011 which has affected some reefs in our  region. Coral bleaching has occurred at a limited number of dive sites  throughout Thailand and beyond. The government of Thailand has taken  some steps to reduce the possible impact of SCUBA diving and snorkeling  on the areas where bleaching has occurred. 
Thailand is home to  more than two dozen Marine Parks and has some of the most highly rated  dive sites in the world. Of these Marine parks, 7 have dive sites that  will be closing. Of these 7 parks, a total of 16 dive sites will close.  In the most famous of all these marine parks - The Similan Islands -  only two dive sites are closed. In an are covering 140 sq. Km and having  dozens of named dive sites - this has had very little impact on  visitors. The names of the closed divesites are East of Eden and Beacon Reef "
