Diving in the Philippines in April

Conditions in April

So, you’re thinking about diving in the Philippines in April? Great choice! This month falls smack dab in the middle of the prime dry season, meaning you're in for some truly spectacular conditions. You can generally expect warm, sunny weather and stable seas, making for comfortable boat rides and surface intervals. Air temperatures hover around a balmy 28-32°C (82-90°F), perfect for catching some rays between dives. Sea states? They're usually exceptionally calm, especially in protected areas, though you might encounter a bit of a chop in more exposed passages or during stronger winds, which are rare this time of year.

The water temperature in April is consistently warm across most of the archipelago, typically ranging from a delightful 27-29°C (81-84°F). This means a 3mm shorty or even a rash guard might be all you need, though a full 3mm wetsuit can provide extra comfort and protection for longer dives. Visibility is often outstanding, reaching an impressive 20-40 meters (65-130 feet) in many popular dive spots, though it can vary locally depending on currents, sedimentation, and plankton blooms. Speaking of currents, they can be mild to moderate in some areas, particularly around channels and reef corners, which is often a good thing as these currents bring in nutrient-rich water, attracting a greater diversity of marine life.

What you will see

April in the Philippines is a fantastic time for marine life encounters, offering a high chance of spotting both large pelagics and fascinating macro critters. For the big stuff, look no further than the thresher sharks of Malapascua. While they're present year-round, the calm conditions of April often make for easier access to Monad Shoal, their cleaning station, giving you a better chance to witness these elegant, long-tailed sharks. Whale sharks can also be encountered in various locations, with Southern Leyte and Donsol Bay still offering good opportunities, although Donsol is more about snorkeling interactions. Don’t be surprised to encounter reef sharks – white-tips and black-tips are common on many healthy reefs throughout the Visayas.

Mantas are another highlight, particularly around Bohol’s Cabilao Island and the Tubbataha Reefs Natural Park. During April, the conditions are often perfect for these majestic creatures to congregate at cleaning stations and feeding grounds. You might also spot eagle rays gracefully gliding past. For macro enthusiasts, the Philippines truly shines. Critters like ornate ghost pipefish, pygmy seahorses, flamboyant cuttlefish, various nudibranchs, and a plethora of frogfish species are abundant in places like Anilao and Dauin. The clear waters and stable conditions in April just make them all the more enjoyable to find and photograph.

Top dive sites this month

When planning your April dive trip to the Philippines, definitely put Tubbataha Reefs Natural Park at the top of your list. This UNESCO World Heritage site is only accessible by liveaboard during a limited season, and April is prime time. Expect incredible visibility and an abundance of pelagics: reef sharks, whale sharks, manta rays, hammerheads, and even tiger sharks have been sighted here. The pristine coral gardens are also breathtaking. Another must-visit is Malapascua Island. While thresher sharks are its main draw at Monad Shoal, the surrounding dive sites like Gato Island offer fantastic macro opportunities, often with sea snakes and diverse nudibranchs.

For a mix of everything, consider the Visayas region. Moalboal in Cebu is famous for its sardine run, a massive school of sardines that aggregates year-round, but April's good conditions make it a true spectacle. Nearby, Pescador Island offers healthy corals and a chance for reef sharks. Finally, Anilao in Batangas is a macro photographer's dream. While it’s good year-round, the calm waters of April contribute to excellent visibility for spotting rare critters like hairy frogfish, blue-ringed octopuses, and a myriad of colorful nudibranchs. This region is easily accessible from Manila and offers a huge variety of dive sites from muck dives to coral gardens.

Practical tips for your trip

Given the lovely warm water temperatures of 27-29°C (81-84°F) in April, you’ll likely be comfortable in a 3mm shorty or even a full 3mm wetsuit if you tend to get cold easily or are doing multiple dives a day. For those who prefer to keep it light, a rash guard plus shorts or leggings can suffice. This month is fantastic for divers of all levels. Beginners will appreciate the calm conditions and clear visibility, making it easier to master buoyancy and enjoy the underwater world. More advanced divers will love the drift dives, deeper pelagic encounters, and the challenging macro spotting opportunities.

Liveaboard availability in April, especially for sought-after destinations like Tubbataha, can be tight. It’s highly recommended to book your liveaboard well in advance – think 6-12 months ahead – to secure your spot. For land-based trips to places like Malapascua, Moalboal, or Anilao, while usually more flexible, booking accommodation and dive operators a couple of months out is still a good idea, particularly if you have specific preferences. Don’t forget to pack light layers for topside comfort, plenty of reef-safe sunscreen, a good hat, and mosquito repellent, especially for evenings. A travel adapter for Type A, B, and C outlets is also useful. Be aware that while April is dry season, occasional short-lived showers can still occur, so a light rain jacket isn't a bad idea, just in case. Enjoy your adventure!
