Hawksbill turtle

Open year-round. Shore diving in a sheltered bay with resident operators, so there is no season closure and no fleet to reposition. Wet season (Dec-Feb) costs visibility, not access.

No closure, but Dec-Mar brings rough surface conditions and frequent same-day cancellations at Manta Point and Crystal Bay. Operators keep running; the boats just turn back more often. Book buffer days in those months.

The hardest access window in this dataset. Roughly mid-March to mid-June only, which is why March and June read 'limited' rather than 'open'. Outside it the northeast monsoon (Nov-Mar) and southwest monsoon (Jul-Oct) make the crossing to an exposed mid-sea atoll unsafe. Nothing about the reef changes; you simply cannot get there. Boats sell out 9-12 months ahead as a direct result.

Less common than greens here.

No closure. Both sources put the optimal window at roughly November/December to May; Jun-Aug stays good with fewer people; Sep-Nov drops in visibility and carries typhoon risk, which is why those months read 'limited'. The sardines are there regardless.

Open year-round. Jun-Sep is the southwest monsoon with more rain, wind and reduced visibility, and the western sites blow out, so those read 'limited'. The whale sharks are there regardless; the diving around them is just less pleasant.

The atoll is open and divable all year, but Hanifaru Bay itself is a seasonal southwest-monsoon phenomenon running roughly May to December. Outside that window the resorts and dive sites operate normally and the bay is simply empty, so Jan-Apr reads 'limited' rather than 'closed': you can go, you will dive, you will not see the thing Baa Atoll is famous for.

Open year-round with no closure; this is the sheltered end of the Red Sea and the reason the north has a twelve-month resort economy while the southern offshore itineraries do not. Winter brings wind and cooler water, summer brings heat and crowds, neither stops the diving.
