May's weather in detail


Kota Kinabalu, Kinabalu NP, Kinabatangan River, Danum Valley, Sepilok, Gaya Island, Lankayan & Selingan Islands, Mabul & Sipadan Islands

The good news continues throughout Sabah in May, with dry, sunny days the norm, although infrequent showers should still be expected especially in the rainforest. Favourable dive and snorkelling conditions continue around Gaya Island and Lankayan Island. Jungle walks are also excellent at this time of year with a higher chance of spotting orang-utan in Danum Valley and around the Kinabatanagan River.

Avg daily temp: 29°C; avg monthly rainfall: 175mm.


Kuching, Damai Beach, Miri, Mulu National Park, Batang Ai

May sees slightly more rainfall in Sarawak than in April, but this shouldn't deter visitors. Conditions for jungle walking and trekking are amongst their best, although a tropical storm can set in at any time of year and suitable clothing is always recommended. Favourable weather in Sarawak coupled with equally good weather in neighbouring Sabah makes May one of the best months of the year to visit Borneo.

Avg daily temp: 28°C, avg monthly rainfall: 240mm.
