Plan Your Trip · Seasons
A highland climate, cooler than coastal Indonesia at 12–25°C year-round, with one season for trekking and one to avoid.
Quick answer
Go between April and October, the dry season. June to September is peak, with the best trail conditions; November to March is heavy rainy season and best avoided.
The dry season begins and trail conditions improve by the day, with some residual rain showers. International visitor numbers are low, making it a good-value window.
Peak conditions begin: dry, stable trails and crystal-clear days, with fewer visitors than high summer. Highland temperatures sit at 12–20°C.
June brings the coldest mornings of the year — you will want a fleece.
Peak Baliem conditions: dry trails, clear days and 13–22°C. Visitor traffic peaks, but Baliem stays uncrowded next to Bali or Komodo.
Pig festivals are sometimes scheduled, often with only 1–2 weeks’ notice.
Peak conditions continue with slightly warmer days of 15–23°C. Pig festivals are more commonly scheduled, and visitor traffic starts to ease.
The last reliable trekking month. Conditions are still good but variable, with a slight chance of early rain showers late in the month.
Heavy rainy season. Trails deteriorate quickly and some homestays close for the season. Local festivals continue, but access for international visitors is poor — avoid this window for trekking.
Traditional pig festivals are scheduled by village elders, timed to sweet-potato harvests, marriages or conflict resolutions. Visitors can sometimes attend, with explicit village permission.
We confirm the festival schedule 2–3 weeks before departure when possible.
