If you planning a diving trip here, you should plan your visit between June until October, during the rainy season, these months are the best diving months in this area, the best visibility, the warmest temperatures, the most marine life, the smallest crowds...etc. The rain really doesn’t affect you as divers, as marine scientists study, the rains also tend to coincide with the return of the bull shark diving at the Bat Islands. During the rainy season here, the days generally are packed with sunshine until mid afternoon, then the rain come down hard for an hour or two, possibly mixed with a fantastic lightning display in the distance over the water, and then it will clear up for the night.
