I just started this same thread. Weather down there is UNFORCASTABLE! Don't count on it being a wash all weekend I've never seen more than a few hours of rain in the caribean before the sun is back out
In Jamaica, especially this time of year, you get rain, or a thunder storm, every afternoon for 30-60 minutes and then the sun comes back out and the humidity is much lower. It's really kind of cool. Is that how Cancun is as well?
