I have been down in Sanya for the past two weeks, and moved into a three bedroom flat in Xiayangtian last week. The location is wonderful - just a five minute walk from Dadonghai.
I have dutifully ridden my bike down to Dadonghai every morning to check for surf, but it has been flat flat flat. We should start to see south swells soon though, and should have some decent surf throughout summer in Sanya. There is an east swell coming through, so I will hit Shimei tomorrow. Now living in Sanya, I have a whole new set of bus schedules to memorize.
Any Sanya locals, please get in touch. I am getting a little bored with my current activity of streaming BBC World and drinking coconuts all day long.
