The most popular time to visit Sumatra is during the dry season, which typically spans from May to September. This period boasts pleasant weather, with average temperatures ranging from 25 to 30°C, making it ideal for outdoor adventures such as hiking through lush rainforests and exploring captivating wildlife.
During the peak season from June to August, Sumatra attracts numerous tourists eager to experience its natural beauty and vibrant culture. While you can expect busier tourist spots during these months, the lively atmosphere adds to the excitement of exploring the region's stunning landscapes, from the breathtaking Lake Toba to the majestic Bukit Lawang rainforest.
For those who enjoy outdoor activities, the dry season offers excellent conditions for trekking, birdwatching, and visiting local markets. The warm temperatures and lower humidity create a comfortable environment for sightseeing and immersing yourself in the local culture. Plus, the longer daylight hours allow you to make the most of your adventures.
If you are looking for a more budget-friendly option, consider visiting in October. While this month marks the beginning of the rainy season, it can still be a great time to experience Sumatra's beauty, with fewer tourists and lower accommodation prices. You can enjoy the lush landscape and the vibrant colours of nature while benefiting from more tranquil surroundings.
