Bali in August

In the middle of the dry season, one of the drier months. August 17 is Indonesian Independence Day, celebrated across the country. Peak season continues, so book popular rooms and restaurants ahead. A light layer helps at night.

It was a hot month: 28°C by day and 24°C after dark. Daily swings were small, about 4°C, with no sudden drop at dusk. With 11 rain days on average, a wet day was rarely more than a few days away. A visitor in 2011 met 2 rain days; one in 2010 met 21. The average of 11 hid that gap.

Rain days averaged only 4 mm each, mostly light drizzle.
