Mataking Island is a tiny, teardrop-shaped private island in the Celebes Sea, roughly 40 kilometers east of Semporna off the coast of Sabah, Malaysian Borneo. The island, whose name translates to "The Eyes of King," consists of two islets, Mataking Besar and Mataking Kecil, connected by a natural sandbar you can walk across at low tide. This is a place built around the ocean: world-class diving across more than 30 nearby sites, an underwater post office where you can mail waterproof postcards from a sunken cargo ship, a turtle hatchery that releases baby green and hawksbill turtles, and coral reefs teeming with clownfish, barracuda, and reef sharks just steps from shore.
Mataking sits near the equator, so it's warm and humid every month of the year with very little seasonal variation. There is no single perfect window the way temperate destinations have one. That said, if you're a diver or snorkeler, the stretch from February through May pairs slightly lower rainfall with calmer seas, and May kicks off turtle nesting season, which runs through August. Accommodation deals tend to appear during the slower months of March, April, August, and September, giving you more resort availability and a quieter island. December and June draw the biggest crowds. If you're flexible, aim for late April into May: you'll catch the tail end of the drier months, the start of turtle activity on the beaches, and moderate visitor numbers before the June peak.
Spring in Mataking Island, Malaysia
March through May marks the transition into Mataking's warmest stretch, though on an equatorial island the difference is subtle. Highs average 89.1°F (31.7°C), and the heat starts building early: the peak arrives in early to mid March, when afternoon temperatures push to 89.8°F (32.1°C) with overnight lows of 73.8°F (23.2°C). Mornings before sunrise are the most comfortable time to walk the sandbar over to Mataking Kecil, the small uninhabited island connected to the main resort. Precipitation is scattered, with just one to three significant rain days per month, and showers tend to pass quickly in the afternoon.
May is the real draw here. Turtle nesting season begins, and lucky visitors can watch green and hawksbill turtles haul onto the beach to lay eggs, or witness hatchlings being released by the resort's full-time marine biology team. The house reef surrounding the island comes alive with activity as water temperatures hold steady. Dive sites like Eel Garden, Coral Garden, and Turtle Playground are all accessible by short boat ride, and the underwater post office on the sunken cargo ship is a year-round novelty worth experiencing. Visibility underwater tends to be decent during these months, making it prime time for both certified divers and beginners trying a discover scuba session.
Tourism runs fairly slow through spring, which translates to accommodation deals at the Reef Dive Resort, the only property on the island. You'll find more room choices and a quieter dining experience at the oceanfront restaurant. Pack reef-safe sunscreen, a rash guard for extended snorkeling sessions, and light breathable clothing, as humidity hovers in the mid to upper 70s percent range.
Summer in Mataking Island, Malaysia
June through August keeps the heat dialed up, with highs averaging 88.3°F (31.3°C) and lows around 73.9°F (23.3°C). The temperature barely shifts from spring, but June brings a noticeable jump in visitors, making it one of the island's busiest months alongside December. If you want the full Robinson Crusoe feeling of having the reef to yourself, this isn't the window for it. Still, the diving remains outstanding. More than 30 dive sites ring the islands in this corner of the Celebes Sea, and summer offers slightly lower-than-average rainfall at two to three significant rain days per month, so boat trips to neighboring islands like Pom Pom and Timba Timba rarely get canceled.
Turtle nesting continues through August, so evening beach patrols with the resort's conservation team are still a possibility. The resort also runs kayaking excursions, jungle walks where you might spot monitor lizards and fireflies after dusk, and fishing trips that the kitchen will cook up for your dinner. The peacock sanctuary on the island is a quirky detour between dives. Winds stay extremely calm through the season, rarely topping a gentle breeze, so the boat ride from Semporna jetty (roughly 40 minutes) is usually smooth.
Accommodation pricing climbs slightly during these months given the higher demand. Book early if you're targeting June, as permits for Sipadan day trips, available through the resort by special arrangement, fill up fast. Bring a good underwater camera, plenty of moisture-wicking layers, and sandals that can handle both sand and reef-edge rocks.
Fall in Mataking Island, Malaysia
September through November is the quietest stretch on Mataking. November in particular sees visitor numbers drop dramatically, meaning you could have entire dive sites to yourself. That solitude comes with a trade-off: precipitation picks up to two to four significant rain days per month, and afternoon showers become more frequent and sometimes heavier. Highs hold steady at 88.8°F (31.6°C) with lows near 74°F (23.3°C), so it's not cooler, just wetter. The humidity edges up toward 81% by November, the most humid reading of the year, leaving the air thick and sticky between rain bursts.
Diving is still entirely viable. The house reef never closes, and most boat-based dive trips run unless conditions are truly rough. Macro diving fans will appreciate the coral gardens off Mataking Kecil, where leaf fish, nudibranchs, and ribbon eels hide among soft corals and anemones. September's rainfall stays moderate, making it a reasonable month for snorkelers who don't mind the occasional downpour. The sandbar walk to the small island is especially photogenic when skies clear after a storm and late afternoon light hits the shallow turquoise water.
Accommodation is priced affordably during fall, and you'll have more flexibility in room assignments. A lightweight rain jacket and dry bags for electronics are essential this time of year. Days run a consistent 12 hours of light, with sunset arriving before 6pm, so plan your last dive or snorkel accordingly.
Winter in Mataking Island, Malaysia
December through February is Mataking's busiest season. December draws the largest crowds of any month, many of them honeymooners taking advantage of the island's beachfront wedding chapel and private dinner setups under the stars. The resort also hosts cultural performances and expanded dining menus at its oceanfront restaurant during high season. Highs average 88.2°F (31.2°C) with lows of 73.9°F (23.3°C), and while it's technically the coolest season by a fraction of a degree, you won't feel the difference. The warmth is constant, and evenings on the sundeck are balmy enough for cocktails without a jacket.
Rain comes two to four times per week during winter, though January and February gradually dry out compared to the November peak. February is one of the drier months of the year. Winds remain light throughout, and the seas between Semporna and the island stay manageable for the 40-minute speedboat transfer. The underwater post office on the deliberately sunken cargo ship is a year-round attraction, but there's something especially satisfying about mailing a waterproof postcard home during the holiday season. Diving conditions stay strong, with visibility often reaching 20 meters on good days at sites like D'Wall off Mataking Kecil, where drift dives along dramatic coral-covered walls reward experienced divers.
Expect to pay premium rates and book well in advance for December and January. February starts to ease off in both pricing and crowds, making it a smart compromise if you want the drier winter conditions without fighting for a beach chalet. Pack a wide-brimmed hat, high-SPF sunscreen, and water shoes for exploring the reef flats at low tide.

Travel Tips & Safety for Mataking Island, Malaysia
Getting to Mataking requires some planning. Fly into Tawau from Kuala Lumpur or Kota Kinabalu, then arrange a transfer to Semporna (about an hour by road), followed by a 40-minute speedboat ride to the island. The resort typically coordinates the entire journey as part of your booking. There's limited phone signal on the island (only certain Malaysian carriers), and wifi is not available, so plan accordingly if you need to stay connected.
Mataking is a small, private island and generally very safe. The main practical concerns are sun exposure and marine hazards: wear reef-safe sunscreen, bring protective footwear for reef walking, and follow your dive guide's instructions around currents, which can be strong at certain sites like North Point. Stay hydrated in the equatorial heat, and if you plan to dive, consider purchasing dive travel insurance before your trip.
