Season
Diving and snorkelling continue year-round, but the whale shark tour fleet only operates March to June or August depending on the base, and the humpback swims July to October. Nov-Feb is the Australian summer wet and cyclone season on this…
Why dive here

SNORKEL ONLY. This is the single most important field in the record. The whale shark season is a tightly licensed surface swim: spotter aircraft locate the animal, the boat holds off, and groups of up to 10 swimmers enter with a guide. Scuba is not how this…
Seasonality — absentabsentshouldershoulderpeakpeakshouldershoulderoffoffabsentabsent

Surprise relative to the headline, and a big one. Ningaloo is booked entirely on whale sharks, and the Navy Pier is regularly rated among the best shore dives in the world: a working military jetty whose pylons are packed with soft coral, sponges,…

Also under-marketed. Mantas with wingspans reported to 8m are present in the Coral Bay lagoon in every month, unlike the whale sharks, and unlike almost every other manta destination in this dataset there is no season to plan around.

Jul-Oct, over 40,000 animals annually on the Western Australian migration.
A resident individual at the Navy Pier known locally as the BFG, at around 15m.

Minimum certification — Open Water
Undemanding for the most part: shallow lagoon, mild current, warm water, and sources state all certification levels are catered for including snorkellers and freedivers. Two specific caveats. Navy Pier visibility is genuinely poor at 3-10m…
