The best time to visit Kumai is during the dry season, which typically runs from May to October.During these months, you'll experience more consistent sunny weather and lower humidity, making outdoor activities and river excursions much more comfortable. The water levels in the Sekonyer River, which is key for accessing Tanjung Puting National Park, are generally stable, ensuring smooth boat trips for wildlife spotting. This period is ideal for those planning multi-day orangutan eco-tours, as the drier conditions make treks through the rainforest more enjoyable and increase the chances of seeing wildlife.While the wet season (November to April) brings lush greenery and fewer tourists, it also means more frequent rain showers, which can sometimes disrupt travel plans or make trekking more challenging. However, if you don't mind occasional rain and prefer a quieter experience, the wet season can still be a good option. The rainforest is particularly vibrant during this time.
