Diving in the Philippines in August

Conditions in August

So, you’re thinking about diving the Philippines in August? Let’s get straight into it. This time of year falls squarely within the country’s wet season, or southwest monsoon (habagat), which usually peaks from July to September. What does that mean for your dive trip? Well, it’s not always sunshine and calm seas, but it’s far from a reason to stay home. Expect more frequent, though often short-lived, rain showers, and sometimes stronger winds. This can lead to choppier surface conditions, especially in more exposed areas, so if you’re prone to seasickness, come prepared.

Visibility can fluctuate more than during the dry season, ranging anywhere from a superb 20-30 meters (65-100 feet) on a good day, particularly in sheltered bays or away from heavy rainfall, down to a more modest 10-15 meters (30-50 feet) if there’s been significant run-off or increased plankton. Water temperatures remain wonderfully warm, generally hovering between 27-29°C (81-84°F) across most dive regions, so you’ll be comfortable even with multiple dives a day. Currents can be variable, as they are year-round, but August’s weather patterns might bring slightly stronger or more unpredictable currents in certain channels, offering thrilling drift dives if you're up for it. While some northern sites might be more affected by weather, many central and southern locations still offer fantastic diving.

What you will see

August in the Philippines, despite the wetter weather, is still a vibrant time underwater, especially if you know where to look. While it might not be peak season for mass aggregations of certain pelagics, you’ll definitely encounter the usual suspects. Think of the resident thresher sharks at Malapascua, which are there year-round and consistently reliable for their early morning cleaning station rituals at Monad Shoal. You might also spot grey reef sharks, whitetips, and even the occasional hammerhead passing through deeper sites. Manta rays are always a thrilling sight, and while not in their biggest aggregations, places like Ticao Pass near Donsol can still deliver encounters.

Beyond the big stuff, the Philippines is a macro paradise, and August is no exception. Nudibranchs in every imaginable colour and pattern, pygmy seahorses clinging to gorgonian fans, frogfish perfectly camouflaged on sponges, and a myriad of colourful reef fish are all present. Keep an eye out for robust ghost pipefish, various species of pipefishes, and intricate crinoid shrimp. While some specific seasonal aggregations of whale sharks might be less predictable outside of their peak months, a lucky encounter is never out of the question, especially in areas like Southern Leyte or Ticao, where they are more consistently present. The increased plankton in the water can also support a richer diversity of smaller creatures, making for excellent critter hunting.

Top dive sites this month

Given the August conditions, smart choices for dive sites can make all the difference. Heading central and south generally offers better protection from the stronger effects of the southwest monsoon. Malapascua remains a top contender; as mentioned, the thresher sharks at Monad Shoal are a daily spectacle, regardless of the surface weather. Its other sites, like Kimud Shoal for hammerheads (though less reliable in August) and deep wall dives, are also excellent. Being a smaller island, its dive operations are well-versed in navigating seasonal conditions.

Another excellent choice is the Visayas region, particularly around Moalboal, Cebu. The Sardine Run at Panagsama Beach is a mesmerising, year-round phenomenon, offering incredible close-up encounters with millions of sardines, often attracting predatory trevally and sometimes even thresher sharks. Nearby Pescador Island boasts stunning walls and vibrant macro life. For something truly special, consider a liveaboard journey to Tubbataha Reefs Natural Park. While often finished by early June due to extreme weather risk, some liveaboards might offer extended (and riskier) late season trips into July; August is generally considered the off-season here. However, for sheer bio-diversity and pelagic action, it’s unparalleled if you manage to hit a weather window. A more consistently accessible option in August would be the dive sites around Anilao, Batangas. While primarily a macro hotspot, its calm bays and sheltered waters make it a perfect destination for critter enthusiasts, offering extraordinary opportunities for underwater photography even when the seas elsewhere are a bit rougher.

Practical tips for your trip

Since the water temperatures are warm, a 3mm shorty or full wetsuit will be perfectly comfortable for most divers. If you tend to get cold easily or are doing multiple dives a day, a 5mm suit might be a good idea for added warmth and protection. August is generally better suited for intermediate to advanced divers due to the potential for choppier seas and stronger currents, especially if you plan to venture to more exposed sites. However, many sheltered bays and shore dives remain perfectly suitable for beginners, so don’t write it off entirely if you’re new to diving – just be sure to choose your destination wisely or discuss conditions with your dive operator.

Liveaboard availability in August can be good, as it's not peak season, meaning you might find better deals and less crowded boats. However, some liveaboards might shift their itineraries to more sheltered areas or even take a break for maintenance during this period, so book well in advance to ensure your preferred route is running. What to pack? Definitely motion sickness medication if you're prone to it, a light rain jacket, quick-dry clothing, and plenty of reef-safe sunscreen. Be aware that domestic flights might experience delays due to weather, so factor in some buffer time around your international flights. Embrace the lush green landscapes that the rain brings, and remember that even in the wet season, the Philippines’ underwater world remains one of the most spectacular on Earth.
