You answer:

I went last year in April and it was honestly amazing — calm seas, warm water, and some of the clearest snorkeling I’ve ever done. The guides told us that April and October are the months when the winds switch, so you get those crystal clear lagoons that make diving incredible. If you want something more detailed, I actually found this page useful when planning: https://charterclick.sc/. It helped me figure out not only the seasons but also what activities fit best depending on the time of year. My tip: if your main goal is diving and visibility, stick to those transition months. If you prefer steady breezes for sailing, May to September might work better.
