Siargao centres on the Cloud 9 reef break, the Magpupungko rock pools at low tide, the Sohoton lagoon's stingless jellyfish, and the offshore Naked, Daku, and Guyam islands accessible by outrigger boat.
Cloud 9 surf at peak with the Siargao International Surfing Cup typically late September, sea visibility at year-best, and the Magpupungko rock pools reliably calm.
Hot dry season with Magpupungko at peak low-tide visibility, Sohoton lagoon swimming pleasant, and the surf scene quieter with smaller swells.
Surf swells building toward peak, but typhoon risk peaks August, and the rainy-season rates drop across General Luna's beachfront accommodation.
Cool dry season with Christmas through New Year at peak resort demand, surf still active at Cloud 9, and island-hopping at year-clearest visibility.
