I'll respond on the assumption that you're not joking.
There's no surfing near Ambergris Caye, because there's no surf. The barrier reef that runs the length of the country breaks the waves apart, so the only substantial waves are outside the reef (a half-mile off shore). What's more, the past few days have been windless and pristine, so the ocean is like a clear lake.
Big winds are headed for us at the end of the week, though! So windsurfing is a real option.
