What is the nasty sludge about a meter into the water everywhere off the beach? Can only think it’s sewage related...a little bit disgusting
Cannot offer a scientific reply but the sea round Samui is mostly very shallow. This means that the sea bottom is moved a lot which (I'm guessing) makes for the sludgy feel. Generally it is an issue for clarity - hence not great snorkelling. But on the bright side it means the water is like a warm bath - if you like that.
Mud, oil, sun cream ? Sewage will smell
Without actually seeing this, I suspect it is probably seaweed, that has just washed up, it seems to be an annual thing here about this time of year... ,
You mean on the sea bottom? Yeah, it's a kind of seaweed or algae. It tends to sit there when the tide is low and there's not much movement in the water, which is around this time of the year.
Doesn't feel very nice underfoot, but is completely harmless.
looked like seaweed when I was there
Bhoput beach has been like this as long as I can remember. I think its from the speedbaots and boats. Its horrid, reason why I stopped going to Bophut beach a long time ago.
