About Siargao

Siargao's Cloud 9 reef break draws surfers from August to November, and the island's lagoon, mangrove rivers and islets fill the rest of the days. Boat trips reach Naked, Daku and Guyam islands, and the Sugba lagoon and Magpupungko rock pools are within a scooter ride. The surf season peaks from August; March to June is calmer for island hopping, and the rainy months are quiet.
