travelling in May (end)/June (start) and want to know some info about weather forecast accuracy. I'm planning to do some island hopping (Phi Phi, Hong) and since it is low season in Andaman, it all depends on weather. So the question is: how accurate is weather forecast? Is it possible to know +- weather, say, one week/3-4 days in advance? Short showers and thunderstorms is not a problem, but all day rain or strong overcast without sun is not very nice, so in that case we could change our plans and move to Gulf coast..
Thank you very much!
