Best Time to Visit in Borneo (Sabah)
Part of the Borneo (Sabah) travel guide — see every topic in All Borneo (Sabah) Guides.
Sabah is equatorial and hot all year — 30–32°C on the coast, cooler at altitude — with no dry season in the strict sense. What varies is rainfall and sea conditions. Broadly, March to September is the drier and calmer half, best for climbing Mount Kinabalu and for diving; October to February is wetter, with the north-east monsoon bringing heavier rain and rougher seas to the east coast in particular. Wildlife viewing works year-round.
The drier months
March to September gives the most reliable weather: lower rainfall, calmer seas, better underwater visibility around Sipadan and Mabul, and the highest chance of a clear summit morning on Mount Kinabalu. It is also the peak season for the mountain, so permits book out furthest ahead in these months. April to August is the core of it. The trade-off is higher prices and fuller lodges, and the possibility of regional haze from land clearing between roughly June and September in some years.
The wetter months
October to February brings the north-east monsoon, with heavier and more frequent rain, rougher seas on the east coast and occasional cancelled boat trips. Diving continues but visibility is more variable. Mount Kinabalu climbs still run, with a higher chance of rain and cloud on the summit. Prices fall and lodges are quieter. January and February are generally the wettest. It is not a closed season, and for wildlife it can be a good one — fruiting seasons draw animals to the riverbanks.
Wildlife timing
Orangutans, proboscis monkeys and hornbills are seen year-round along the Kinabatangan. Pygmy elephant sightings are unpredictable and depend on herd movement. Fruiting seasons, broadly around the middle of the year and again later, concentrate primates and hornbills. Turtle nesting at Selingan island near Sandakan happens year-round with a peak roughly July to October. Diving at Sipadan is good all year, with the calmest seas and best visibility from about April to August.
Festivals and holidays
Kaamatan, the Kadazan-Dusun harvest festival, runs through May with state holidays on the 30th and 31st, and is the most interesting time to be in Sabah culturally — expect celebrations in villages across the state. Malaysian school holidays and Chinese New Year fill flights and hotels. Hari Raya sees domestic travel spike. Mount Kinabalu permits are hardest to obtain around all of these, and around weekends generally. Book the mountain first and build the rest of the trip around whatever date you get.
