Diving in Bali in November

Conditions in November

So, you're thinking about diving in Bali in November? Let's talk brass tacks. November marks a transitional period for Bali's weather, moving from the drier, cooler months towards the wetter, hotter rainy season. This means you can expect a mixed bag, but generally favorable conditions. The air temperature hovers comfortably between 27-32°C (81-90°F), often with occasional afternoon showers that typically don't last long enough to disrupt your diving plans. These rains are usually a welcome cooldown rather than a hindrance.

The sea state in November is largely calm and inviting, particularly around the Nusa Islands and the eastern coast. You’ll find the water temperature to be deliciously warm, ranging between 27-29°C (81-84°F), which means a 3mm shorty or even just a rash guard and board shorts will suffice for most divers. Visibility is generally excellent, often hitting 20-30 meters, especially in areas like Nusa Penida. However, it can drop slightly to 15-20 meters after heavy rainfall, as runoff from the land might affect some coastal sites. Currents, famously present around the Nusa Islands, remain a factor in November, ranging from gentle drifts to exhilarating rides, depending on the site and tidal movements. This makes some sites better suited for experienced divers, but there are plenty of sheltered spots too.

What you will see

November in Bali is a fantastic time for marine life encounters, especially if you’re keen on pelagic action. While the prime season for Mola Mola (oceanic sunfish) is typically July to October, you still have a decent chance of spotting these majestic giants in early November, particularly around sites like Crystal Bay. However, the real stars of the show are the manta rays; November is often considered one of the best months for consistent manta sightings. Their cleaning stations at Manta Point and Manta Bay become bustling hubs of activity, offering incredible opportunities to observe these gentle giants gliding gracefully through the water.

Beyond the big stuff, Bali's renowned macro scene is thriving in November. You'll delight in discovering a myriad of critters, from pygmy seahorses clinging to gorgonians, to colorful nudibranchs crawling along coral reefs. Keep your eyes peeled for ornate ghost pipefish, various species of frogfish, and an incredible array of crustaceans hiding in the crevices. Reef sharks, including white-tip and black-tip reef sharks, are common residents across many dive sites, and you might even spot the occasional leopard shark resting on the sandy bottom. The healthy coral reefs, bursting with vibrant hard and soft corals, provide the perfect backdrop for this diverse ecosystem, attracting schools of reef fish that create a kaleidoscopic underwater spectacle.

Top dive sites this month

For an unforgettable November diving experience, Nusa Penida should be at the top of your list. Its world-famous sites like Manta Point and Crystal Bay deliver consistent manta encounters and offer lingering chances for Mola Mola in early November. Drift dives along the northern coast of Nusa Penida, such as SD Point or Mangrove, are exhilarating and showcase vibrant reef ecosystems. Over in East Bali, the wreck of the USAT Liberty at Tulamben is an absolute must-dive. Its shallow depth and resident marine life, including bumphead parrotfish and various smaller critters, make it accessible and rewarding for all levels of divers, especially in the generally calm November seas.

Another gem in East Bali is the Amed region. Here, you'll find healthy coral gardens, fascinating muck diving opportunities, and several smaller wrecks like the Japanese Wreck. Amed is particularly good for macro enthusiasts, with plenty of nudibranchs, frogfish, and critter hunting. The absence of strong currents at many Amed sites makes it a very relaxed and enjoyable experience. Finally, for something a bit different, consider diving Menjangan Island in West Bali. Though a longer journey, its pristine coral walls, cave systems, and excellent visibility make it a rewarding trip, offering a diverse array of reef fish and often stunning dramatic reefscapes.

Practical tips for your trip

Given the warm water temperatures of 27-29°C (81-84°F), you’ll find a 3mm shorty wetsuit or even a 3mm full suit perfectly adequate. Some divers opt for just a rash guard for added sun protection. November diving in Bali caters to a wide range of experience levels. Beginners will find the sheltered reefs of Tulamben and Amed incredibly welcoming, offering calm conditions and abundant marine life. More advanced divers will relish the exhilarating drift dives and potential strong currents around Nusa Penida, where the bigger pelagics are found. Always listen to your dive guide, especially when navigating the currents around the Nusa Islands.

While Bali doesn't have the extensive liveaboard options of a Komodo or Raja Ampat, there are often day trips and multi-day packages available that include accommodation on land and transfers to the dive sites, particularly for the Nusa Islands. Booking in advance is always wise, especially for popular dive centers and specific itineraries. Don't forget to pack reef-safe sunscreen, a good quality dive computer, and an underwater camera to capture all those amazing encounters. Be aware that while November is generally good, it is the start of the wet season, so prepare for occasional rain showers by bringing a lightweight rain jacket and dry bags for your electronics. Embrace the transition – it often brings surprising marine encounters!
