The Daymaniyats are nine uninhabited islands and a protected reserve, and they are the reason Oman is a diving country rather than a stopover. Granite and coral from 5 to 30 m, turtles nesting on the beaches and resting under every ledge, and whale sharks aggregating from late summer into November. The Arabian Sea's upwelling makes the water green and cold for a month in summer and clear the rest of the year — September to November is when both the visibility and the whale sharks are there. The reserve closes to landing in nesting season; diving continues.

An hour by boat from Al Mouj or Bandar Al Rowdha in Muscat. Permits are handled by the operator.

Before you get in

A wall. There is no bottom in sight to judge against, so depth is kept by the gauge alone — and it is easy to end up deeper than intended.

Taken from this site’s recorded depth, type and current, and nothing else. An empty list is not a safe site — the sea on the day, the local geography and the boat traffic are not in it. The briefing on the spot comes first.

Sea state and tide

Forecast heights against mean sea level. Real tides in a bay, a harbour or over a flat can differ — check an official tide table before you get in.

Only wave height and wind are scored, because those are what close a boat ramp or a shore entry. Water temperature is reported and never scored: 12°C is an ordinary dive in a drysuit and punishing in a 3 mm, and a number that cannot see your suit has no business marking it down. Stars do not decide whether you get in — you and your guide do, on the day.
