Shaviyani Atoll
10 registered properties on 8 measured reefs. Shaviyani — North Miladhunmadulu — is a northern fishing atoll of long fringing reefs and quiet islands, its seat at Funadhoo. Tourism has come late and lightly, leaving its reefs among the least-visited in the country.
What’s actually known about the timing.
One assessed site, for a critically endangered ray most visitors will never have heard of.
The dry season, and the shorter of the two. Currents run east to west. Clearer water, calmer seas, less plankton.
The wet season, and the longer one. Currents reverse to run west to east. Lower visibility, because the water is thick with the plankton the big filter-feeders come for.
The two seasons are not symmetric — the northeast monsoon is shorter and weaker, and April and December are transitions rather than a clean switch.
Which side of the atoll — and why the answer is two answers
One atoll has two different answers at once, and they are on opposite sides. The upstream flank takes clear ocean inflow, so that is where visibility is best. The downstream flank is where plankton piles up — so that is where the mantas feed. In the northeast monsoon the east side is the clear one and the west side is the feeding one; in the southwest monsoon they swap. A reef facing east is therefore a clear-water proposition in January and a manta proposition in August — not "better" in either, just different.
This is an atoll-scale pattern, not a per-reef rule. Whether animals actually aggregate still depends on local shape — a lagoon or channel that traps the plankton. Channel sites are tide-driven and fit it less cleanly, and Fuvahmulah, a lone oceanic platform with no lagoon, sits outside it entirely.
Bottlenose wedgefish
Year-roundRecorded year-round at Maroshi Thila over more than a decade — a critically endangered species, with courtship possibly running August to February.
What we don’t know about Shaviyani Atoll
- Turtles — no atoll-level seasonal study exists; treat them as year-round residents rather than a season
- Reef sharks — no atoll-level seasonal data
- Mantas and whale sharks — no assessed area in this atoll
These are absent because no public source supports them here, not because nothing lives here. Per-reef sighting odds do not exist in any source we could find — open species records track where divers point cameras, not where animals are. Where you see a month-by-month wildlife chart for an individual resort, someone has estimated it.
