Mount Batur weather and the best time to visit
The best time to visit Mount Batur is usually the drier half of the year, but no month guarantees a clear sky. Bali has a wet and a dry season, and the highlands around Kintamani are cooler and cloudier than the coast. Mist can sit in the caldera at any time, and a sunrise that is perfect one morning can be grey the next. Mount Batur weather is best treated as a pattern to plan around, with the real decision made the day before your trek.
The tables below show what is available: rain recorded at the Batur station in 2022, and long-term averages for Denpasar on the coast as a comparison. Neither is a forecast for a given week.

The coast is far warmer than the volcano, so do not read these temperatures as what you will feel at the top. What carries over is the rhythm: the wet months at the start and end of the year and the drier months in the middle.
Cold before dawn
The park authority warns of very cold air before daybreak on the mountain. You start in the dark, and the wind on the crater edge feels sharper than the daytime weather suggests. Bring warm layers, a windproof top and water, and wear sturdy shoes, since sand makes the descent slippery. Some treks list a rain jacket, walking poles and a torch among the items they supply, so check what your trip includes. The sunrise hike page explains the usual schedule.
Mount Batur in December
December falls in the rainy season. Cloud and mist are possible, so the view can be limited. Check the village forecast for Kintamani the day before, ask your operator about the plan for poor weather and bring a rain layer.
Dry season and fire risk
The dry months bring clearer paths, and also a higher fire risk. BKSDA reported the start of the dry season in the Batur landscape in August 2026 and warned of heightened fire danger. Fires were reported on 30 August, 18 September, 23 September and 6 October 2026, the last covering about 22.77 hectares. Ask your guide or operator for the current situation on the trails the day before, and never throw cigarettes or leave embers behind. Level I (Normal) applied in the PVMBG daily report for 29 October 2026, which is not an all-clear for the crater area. See climbing Mount Batur.
