Located just 8 degrees south of the equator, Bali has a tropical climate all year round. The average temperature hovers around 30 degrees Celsius year-round. There are dry and wet seasons - dry from April to September and wet from October to March - but it can rain at any time of the year and even during the wet season rain is likely to pass quickly. Temperatures range from 30-31 C' by day, 24-25 C' at night in the wet season and 28-29 C' by day, and a pleasant 23 C' at night in the dry season. In general May to August are the best months in Bali. At that time of year the climate is likely to be cooler and the rains lightest.

Around the coast, sea breezes temper the heat and as you move inland you also move up so the altitude works to keep things cool. It can get very cool up in the highlands and a warm sweater can be a good idea in mountain villages like Kintamani or Bedugul.
