Things to Do in Medan in December

December delivers the best Lake Toba experience of the year. The 100 km (62 mile) drive from Medan takes 4 hours through palm oil plantations that turn emerald after the rains, and the lake itself sits at 900 m (2,953 ft) elevation where temperatures drop to a comfortable 22°C (72°F). The ferry to Samosir Island runs every hour instead of the usual 90-minute gaps, and the Batak villages host more cultural performances since December is wedding season. Afternoon storms over the lake create dramatic photo opportunities that you simply don't get during dry season.

December's cooler evenings make walking tours through Medan's food districts enjoyable. Start at Lapangan Merdeka where the old Dutch buildings cast long shadows, then hit three distinct neighborhoods: Kampung Madras for banana leaf curry, Petisah for Chinese-Indonesian fusion, and Kesawan for colonial-era coffee shops where the kopi tubruk still comes in chipped enamel cups. The post-rain air carries the smell of grilling satay for blocks, and since it's durian season, every other stall offers the fruit that's banned from hotels but adored by locals.

While the park is technically open year-round, December offers something special: the orangutans come lower into the canopy after heavy rains, making them easier to spot during the 3-4 hour treks from Bukit Lawang. The 86 km (53 mile) journey from Medan takes 3.5 hours through changing landscapes, and the jungle humidity feels less oppressive when afternoon storms cool things down. River tubing back to the village works even better with higher water levels from December rains.

December's morning light hits the 1888 palace's yellow facades at the perfect angle for photography, and the 30°C (86°F) mornings are manageable before noon showers roll in. The palace's Italian tile floors feel cool under bare feet, a welcome contrast to the humid air outside. Continue through Kesawan's art deco buildings - most built by Dutch tobacco traders in the 1920s - where the afternoon rain creates mirror-like puddles that reflect the colonial architecture.

December's variable weather creates the most dramatic sunset conditions over the Strait of Malacca. The working port at Belawan - operational since 1890 - smells of diesel, salt, and dried fish, while cargo ships from Jakarta and Penang create silhouettes against orange skies. The 45-minute cruise from Belawan jetty runs daily at 5 PM, and December's position just north of the equator means sunsets happen at 6:15 PM sharp, giving you perfect golden hour photography from the water.
