Compare all 14: reefs, access and modelled best months

Wildlife, exact spots and access come from cited travel or conservation sources. Calm-morning percentages and modelled best months appear only for destinations with a complete, comparable 12-month dataset. They measure marine conditions—not reef quality or safe swimming.

How we selected and checked these places

Travel evidence first

We selected different types of experience—wildlife encounters, coral reefs, easy shore entry and boat adventures—using park authorities, tourism boards and conservation sources. Follow each source link to check the claim. This is a curated guide, not an invented biodiversity score.

What the calculations mean

For coverage-qualified locations, we reuse the same 12 complete months of historical modelled wave, wind and temperature inputs. “Calm mornings” and “top-scoring months” never imply that nearshore currents, underwater visibility or wildlife have been measured—or that entering the water is safe.

Photographs and review

The selected photographs are Creative Commons media, with the creator and license beside each photo. This guide was reviewed on 11 October 2026; entry rules, wildlife, sea conditions and availability can change. Confirm details before travelling.
