What snake is this?

Hello guys,
I just saw this snake on the beach at Koh Phayam, Thailand, and I would really like to know what it is. Can anybody recognize it? This is unfortunately the closest I dared to get to it with a camera without zoom, so I can't supply a more detailed shot.

There is no picture. You can PM it to me if the forum wont let you post it.
