What is the weather like?
Balinese weather is tropical and mostly hot and sunny. Days are almost always 12 hours long. Sunrise is around 6:20 a.m. The sun sets around 6:30 p.m. The daytime temperature averages between 27ºC (80º F) to 32ºC (90º F) in the southern lowlands. In Bali however, it is quite humid at about 75% so often times it feels much hotter. The mountains tend to be significantly cooler at around 21ºC (70º F) to 27ºC (80º F). At night the mountains can get pretty chilly.
Bali has two seasons: dry (between May to September) and wet (between October to April). However even in the wet season, it is still likely it will be sunny for most part of the day.
