November on Sipadan
I spend ten months of the year watching guests count down to their Sipadan permit day. Then November arrives and the pinnacle goes completely dark. People book flights without checking the calendar and panic when they realise the island is locked. After years of running boats out of Semporna my honest pitch is this: a closed island is a large logistical advantage. Sabah Parks shuts the reef for thirty days because the local dive operators asked them to. We lose a month of revenue so the coral gets a biological deep breath. The result is a dive schedule that forces you to look at the other islands and a macro season that gives some of the strangest animals in the Celebes Sea.

The conservation sacrifice
Every morning at six the boats normally race for the drop-off. Sabah Parks issues 254 Sipadan permits a day. Divers and snorkellers draw from the same pool. That means thousands of fins in the water every month. The reef handles the traffic well but constant pressure changes the rhythm of a site. In 2020 the local operators sat down with the regional authorities and asked for a hard stop. We requested a full ban on recreational diving for the month of November. The tourism authorities agreed unanimously.
The arithmetic is brutal for the booking sheets. We sacrifice over seven thousand permit slots to buy the ecosystem thirty days of silence. The logic comes from a grim experiment we all lived through. The pandemic locked the island down for eighteen months and the reef responded like a neglected garden suddenly getting rain. Hard corals pushed out new growth across the damaged shelves. Open-water fish that normally stay deep where the temperature drops started hunting in the immediate shallows. The biology proved that a pause works. We cannot close the island for a year but we can give it November.
The ranger shift and the hatchery
The dive boats stop running but the island is not abandoned. Sabah Parks keeps a permanent crew stationed on the sand to manage the biology. The reef goes completely off the clock while the terrestrial staff work overtime. Green and hawksbill turtles nest on these beaches all year round. The November closure lets them drag themselves up the sand without a single boat engine to spook them.
Rangers walk the tideline every night. They locate fresh clutches and dig them up like fragile munitions. A turtle nest left alone is a buffet for monitor lizards and local rats. The staff move the eggs to a predator-proof hatchery a hundred and fifty metres to the left of the main jetty. The eggs incubate behind high wire fences until they hatch. The whole operation runs invisibly while the dive community stays away.
The monsoon surface and the stable depths
The closure aligns with a large shift in the regional weather. November brings the northeast monsoon to Borneo. Sabah sits safely below the Pacific typhoon belt so the sea is usually kind that month. We do get a scrambled surface. The wind picks up and the afternoon sky bruises over with rain clouds. The crossing from Semporna turns into a bumpy ride that tests your stomach.
The trick is to ignore the sky and look at your computer. I have dived through a turbulent surface into water that felt like a bath. Water temperatures across the archipelago lock in at 27 to 30 degrees Celsius. I have been comfortable for an hour here in a standard three-millimetre wetsuit. The surface chop does churn the sand and drop the visibility to ten or fifteen metres. That sounds like a penalty until you realise you do not need thirty metres of clear water to look at a snail.
Mabul and Kapalai: the macro alternative
Everything Sipadan is not is what makes Mabul work. The deep blue walls disappear. The shape flattens out into sandy slopes and coral rubble. Kapalai and Mabul operate every day of the year and their dive sites ignore the monsoon visibility. You spend your bottom time staring at a single square metre of structure rather than scanning the horizon for sharks.
Froggy Lair turns the sand into a treasure map. The animals here look like bad ideas sketched by a child. Frogfish sit on the sponges like disgruntled tennis balls. Ornate ghost pipefish hover head-down among feather stars and blend into their feathery arms. Seahorses wrap their tails around the debris and stay put. The artificial reef at Kapalai breeds sea slugs in colours that hurt the eyes. I have seen flamboyant cuttlefish walk on their tentacles across the sand. I have spent a week here with a macro lens and never missed the fish out in the blue.
Tun Sakaran Marine Park: the leeward shelter
If you want a wider frame you point the boat north. The Tun Sakaran Marine Park is a cluster of eight dead volcanoes rising out of the sea. The geography provides a large physical shield against the northeast wind. I have found flat water on the sheltered sides of these islands when the open crossings felt like a washing machine.
Sibuan Island sits inside this ring as a prime target for macro hunters. The site slopes gently over coral gardens and patchy rubble. I have hunted for frogfish here in conditions that felt like a swimming pool. Around Mantabuan the reef looks like a construction site. Conservation teams plant thousands of coral fragments onto metal frames to repair old blast damage. You swim over the grids and watch the hard corals slowly swallow the steel.
The terrestrial pivot: Tawau to the Kinabatangan
Divers log up to three dives a day and build up a nitrogen load that demands a surface interval before a flight. A closed Sipadan is the perfect excuse to spend your no-fly day in the jungle. Sabah has a highway network that plugs Semporna directly into the deep forest.
Tawau Hills Park is a thirty-minute drive from the airport town. The reserve covers nearly 280 square kilometres of virgin rainforest. The trees here scrape the sky like wooden towers. You walk the trails to find a Yellow Meranti tree that stands almost 97 metres tall. A moderate hike of two and a half kilometres takes you to the natural swimming pools at Bukit Gelas Waterfall. You can push further on a three-kilometre trek to find hot sulphur springs bubbling out of the volcanic rock. It feels like a different planet compared to the flat sandbars of the coast.
If you have a few days to spare you drive north. A long run of 252 kilometres up the road puts you at Sukau on the Kinabatangan River. The muddy banks are a chaotic circus of wildlife found only in this part of the world. From a small boat I have watched proboscis monkeys crash through the canopy. Wild orangutans build their nests in the high branches while saltwater crocodiles sleep on the mud. Sometimes a herd of Bornean pygmy elephants walks right out of the trees to forage along the waterline.
An overland drive of 277 kilometres gets you to Sepilok. I have seen primates at the sanctuary without the river search. You can reach the deep interior of the Danum Valley if you push 140 kilometres north to Lahad Datu and endure an 80-kilometre drive on unsealed logging roads. The primary lowland forest at the end of that dirt track is the wildest place in the state.
The December reopening
The gates open again on 1 December. Sabah Parks opens the island and the boats rush back to the jetty. A month without exhaust fumes or bubbles leaves the water feeling electric. The fish are calm and the reef feels heavy with life.
The catch is the calendar. The pent-up demand for that first week is immense. The daily permits vanish onto the booking sheets long before the boats even start their engines. You also need serious foresight.
November is the month the archipelago belongs to whoever is already here. Send us your dates and tell us how many of you are diving and we will match the itinerary to the season.
