We are in the thick of peak dry season and locals are actually wearing jumpers at dawn. The Bali Meteorology, Climatology and Geophysics Agency has confirmed what anyone sleeping without AC has felt for weeks: this June is running noticeably cooler than usual across multiple regions.
What is actually happening
Three things are converging, according to BMKG forecaster I Wayan Gita Giriharta. First, the sun has shifted into the Northern Hemisphere, which means Bali, south of the equator, is getting less direct sunlight than it does in December. Second, Australian winter is pushing cold air masses across the archipelago. Third, the usual dry-season cloudless skies mean heat radiates straight back into the atmosphere at night rather than being trapped.
The numbers
Kintamani has recorded lows of 13°C. That is genuinely cold for anyone staying in a villa with tile floors and no heating. Coastal areas like Canggu and Seminyak are holding steady at 19 to 24°C, which is actually pleasant rather than the oppressive 30°C plus humidity of wet season. BMKG forecasts this pattern will hold through July and August.
What this means for your trip
If you are heading inland: Kintamani, Mount Batur, Bedugul and Ulun Danu Beratan need layers. Evenings at outdoor restaurants near the lake genuinely require a jacket right now. Sunrise hikes at Batur will be cold enough that you will want thermals under your outer layer.
If you are on the coast: it is business as usual. Sunscreen, hats, stay hydrated. The UV index is running high despite the cooler air temperature.
Cooler dry season is also better for photography and video. Clearer air, less haze and cleaner sunrise light make the island feel sharper in the mornings.
