When to visit
The best time to travel to Sumatra is during the dry season from May to September. This is the optimal window for jungle trekking in Gunung Leuser National Park to see orangutans, as the trails are firm and river levels are safe. It is also the peak surfing season for the Mentawai Islands and Nias, as massive swells roll in from the Indian Ocean, alongside excellent diving visibility around Pulau Weh in the far north.
The wet season runs from October to April, driven by the northeast monsoon. Torrential rains turn jungle trekking paths into slick mud, cause rivers to flood, and bring out massive numbers of leeches in the rainforest. While travel to urban centers and Lake Toba remains manageable, deep jungle safaris and offshore boat crossings to smaller islands can be heavily disrupted by storms and rough seas.
