Is May Right for You?
Weigh the advantages and considerations before booking
- + Durian season peaks, the pungent fruit costs less and tastes sweeter at the night markets along Jalan Semarang, where vendors stack spiky mountains under bare bulbs.
- + Hotel rates drop 20-30% after the Easter spike, and you'll finally get a pool chair at the Grand Angkasa without a 6 AM towel reservation.
- + Lake Toba ferries run half-empty, so you can claim a window seat and watch the Karo Highlands turn emerald-green after rain.
- + The traditional Karo wedding season means you'll stumble on full-blown processions in Berastagi, complete with gendang music and red ulos cloth.
- − Afternoon storms hit hard at 2-3 PM and can last 45 minutes, enough to soak your camera if you're caught photographing Maimun Palace.
- − Mosquito season is in full swing, around the Deli River where the stagnant water turns into a breeding ground.
- − Some hiking trails in Gunung Leuser National Park become mud slides. Guides might cancel multi-day treks if the previous week's rain has been heavy.
Best Activities in May
Top things to do during your visit
May's afternoon storms clear the haze, leaving the volcanic lake mirror-calm by morning. Ferries leave Parapat at 8:30 AM and 1 PM, the morning boat gives you four hours to explore Tomok's stone chairs and the Batak villages before clouds build over the caldera rim. The water is warm enough for swimming at 26°C (79°F), and you'll share the lake with maybe 30% of peak-season boat traffic.
May is when Medan's durian trees drop their heaviest fruit, and the orchards 40 minutes south let you taste Musang King and Monthong varieties straight from the tree. The air smells like overripe cheese mixed with almonds, and the farmers will teach you how to spot a ripe fruit (listen for the hollow thud when you tap it). Morning starts cool at 22°C (72°F) before humidity climbs.
The pre-dawn humidity at 5:30 AM makes cycling bearable, and you can hit ten food stalls before the sun properly rises. Start at Pasar Ikan Lama for coffee thick as motor oil, then follow the old Dutch canal to Soto Kesawan for turmeric broth with glass noodles. By 9 AM you'll be dripping sweat, but you'll have eaten better than most visitors manage in a week.
The 1,300-meter (4,265-ft) elevation drops temperatures to a comfortable 20°C (68°F), and the Karo villages are preparing for the May harvest festivals. You'll see traditional jambur houses with their buffalo-horn roofs, and if you're lucky, catch a gendang performance where the drums echo off Mount Sibayak's slopes. Morning clouds usually clear by 10 AM, revealing the smoking summit.
May's variable light creates dramatic shadows across the palace's yellow and blue tiles, between 7-9 AM when the sun is low enough to illuminate the interior without the harsh glare that comes later. The afternoon storms help, post-rain light is soft and golden, good for the mosque's black domes against wet marble floors.
May Events & Festivals
What's happening during your visit
Throughout May, Karo families in Berastagi and surrounding villages host elaborate weddings where guests wear traditional ulos cloth and participate in the ulaon adat ceremony. The sound of gendang drums carries for miles, and you're likely to be invited in for tuak palm wine even if you're just passing through.
