The best scuba diving in November sits at a fascinating crossroads of the diving calendar. Rather than bringing uniform peak visibility or identical conditions worldwide, November serves as a transition month. In certain regions, it opens highly anticipated seasonal windows, such as in the remote Pacific, where Socorro Island, Mexico welcomes back giant mantas for the liveaboard season, or in Thailand where the marine national parks are welcoming divers back after being closed through the off season. Conversely, other regions shift into wetter or high-swell weather patterns, such as Australia’s Great Barrier Reef, which nevertheless hosts its most spectacular natural event: the annual mass coral spawn. From pelagic encounters in Oman to localized lunar aggregations in Palau, November delivers extraordinary, time-sensitive marine windows that don’t appear any other month. To secure your spot on these unique itineraries, early booking is essential. Explore our liveaboard special offers to lock in your November diving adventure.

A Closer Look at November’s Top Dive Destinations
Why dive Socorro in November
November marks the start of the liveaboard season at the Revillagigedo Archipelago, a UNESCO World Heritage site. After rough summer seas subside, the crossing from Cabo San Lucas becomes safe enough to reach this remote Pacific gem. Giant Pacific manta rays begin their famous curious interactions, often circling divers for entire dives.
What you will see
Giant mantas that seem to actively seek out the bubbles of scuba divers. On a good dive you can have mantas, hammerheads, silkies and dolphins in the water at the same time.
Pro diver’s tip
The 36-hour crossing can be rough. Pack seasickness medication and consider a few extra days in Cabo to recover before flying home. November offers fewer liveaboards than the January peak, which means less crowded dive sites and more time with the mantas. For a full overview of when to dive in Mexico, see our seasonal guide.
Why dive the Great Barrier Reef in November
A few days after the full moon, the world’s largest coral spawning event transforms the reef into an underwater blizzard of pink and orange gametes. This is a bucket list event for macro photographers and anyone who wants to witness one of nature’s most spectacular reproductive rituals.
What you will see
Hard corals release millions of egg and sperm bundles simultaneously. Reef fish, including snappers and groupers, gather to feed on the spawn, creating a frenzy of activity. Green turtles and reef sharks are also present. The sheer volume of life is unforgettable.
Pro diver’s tip
The exact spawn dates shift with water temperature, typically 3 to 6 days after the full moon. Book a Cairns-based liveaboard that offers night dives. Early booking is essential because demand is high for this natural wonder.
Why dive Palau in November
Around the full moon, huge groups of twin-spot red snapper spawning aggregations draw large numbers of grey reef sharks, as well as bull sharks, oceanic blacktip sharks, and more to southern reef edges, such as Peleliu Cut or Peleliu Wall. The sharks are there for the fish, not for divers, no bait involved. The action happens at dawn, adding to the drama.
What you will see
Thousands of snapper congregate for several days before heading into the blue over, generally, two days. Sharks take advantage of this and sweep in to feed on the spawning fish in a concentrated area. Around the spawning, you will also have the chance to see WWII wreck remnants on Peleliu’s beaches above water. Combine this with Palau‘s signature sites like the German Channel, Blue Corner, and Jellyfish Lake for a complete trip. Jellyfish Lake is featured on certain liveaboard itineraries returning in 2026.
Pro diver’s tip
The spawning window is only 2 to 3 nights per month. Base yourself in Koror, either at a resort or on a liveaboard, and ask local operators for their exact spawning calendar. Advanced buoyancy control is essential for dives in open blue water and current. For more adrenaline, check out our list of top spots to dive with sharks.
Why dive Musandam in November
After the intense summer heat, water temperatures drop to a comfortable 24 to 26°C. This cooling triggers plankton blooms that attract whale sharks and mobularays into the dramatic khors of the Musandam Peninsula.
What you will see
Whale sharks cruising near the surface, mobula rays gliding through the channels, and rich reef life clinging to vertical walls. The above-water landscape is equally striking: The Musandam Peninsula’s khors, steep-sided drowned inlets, are unlike anything else in the region and are often compared to Norwegian fjords.
Pro diver’s tip
Day trips from Khasab on traditional dhows are available, but liveaboards reach the more remote and less crowded sites. A 5mm wetsuit is recommended for deeper dives where thermoclines can drop the temperature quickly.
Why dive Thailand’s Andaman Sea in November
The Andaman Sea liveaboard diving season runs from November to May, and November is the soft opening. The northeast monsoon calms the sea state, and after six months of park closure, the reefs of Tarutao National Marine Park are pristine and rested. For divers wondering where is the best diving in Southeast Asia, Koh Lipe is a strong contender.
What you will see
Hard coral gardens in exceptional condition, leopard sharks resting on sandy patches, and abundant reef fish. Far fewer boats operate here in November compared to the December peak, so you will have dive sites nearly to yourself.
Pro diver’s tip
November is ideal for divers who want uncrowded conditions and don’t mind slightly cooler water temperatures. Combine Koh Lipe with a liveaboard that visits the surrounding islands as part of a longer itinerary, or base yourself at one of the island’s eco resorts for shore diving.
