Im planning on traveling to Thailand in April. My original thoughts were to travel for 90 days but I have a little concern about the weather. Can someone advise on how rainy the months of April, May and June are in southern Thailand (Phuket, Krabi, Samui). Does it downpour for an hour or two every day and then the sun is shining again? Or does it constantly rain every day, all day...am I wasting my time taking my first trip to Thailand in April - July? I could handle daily showers followed by sunshine...but a rain out and constant cloudiness for 90 days seems like it could be a deal breaker.
