Siargao

The most popular dive site in Siargao, Philippines is the Blue Cathedral. It's a large underwater cavern with multiple openings that allow sunlight to penetrate, creating ethereal light effects resembling stained-glass windows. This unique topography, with its chambers and swim-throughs, makes it a thrilling dive and a favorite for underwater photographers. It is best suited for advanced divers due to its depth.

Besides the famous Blue Cathedral, Seeco Reef is a great site known for healthy corals and frequent turtle sightings. For a less-crowded hidden gem, the dive sites off Pilar offer exciting drift dives along walls teeming with fish. Dako Island also has beautiful and shallower coral gardens, perfect for easier dives and spotting macro life away from the main dive traffic.

Water temperatures in Siargao, Philippines are consistently warm and tropical. Expect a pleasant 28-30°C (82-86°F) from March to November. During the slightly cooler, windier months of December to February, the water temperature may dip to a still-comfortable 26-27°C (79-81°F). Diving is comfortable throughout the entire year.

The best time for diving in Siargao, Philippines is during the dry season, from March to October. This period typically offers the calmest sea conditions, sunniest weather, and best underwater visibility. While diving is possible year-round, the monsoon season from November to February can bring stronger winds and rougher seas, which may limit access to some offshore dive sites.

Underwater visibility in Siargao, Philippines is generally very good, especially during the prime diving season from March to October. Divers can often expect excellent clarity ranging from 15 to over 30 meters (50 to 100+ feet). Visibility can be reduced after heavy rains or during the monsoon season (November-February) due to runoff and rougher seas, but usually remains good.

Siargao, Philippines is not known for major, predictable migrations like those in other parts of the country. However, its location near the deep Philippine Trench means surprise encounters with large pelagic species are always possible. Divers have reported occasional, lucky sightings of manta rays, eagle rays, and various shark species, particularly at deeper offshore sites, but these are not guaranteed seasonal events.

Divers in Siargao, Philippines can see a rich variety of marine life. Expect schools of barracuda, jacks, and tuna, along with reef dwellers like angelfish, sweetlips, and butterflyfish. Sea turtles are commonly spotted. The healthy corals host macro life like nudibranchs and frogfish, while reef sharks and eagle rays occasionally pass by the deeper sites.

For the warm tropical waters of Siargao, Philippines, a 3mm shorty or even just a rash guard and board shorts are sufficient for most divers. If you tend to get cold or are planning multiple dives over several days, a 3mm full wetsuit provides extra comfort and protection. A 5mm suit is generally unnecessary.
