Bali Climate and Weather
Lying just south of the equator, Bali has a tropical monsoon climate with two distinct seasons: wet (November to March) and dry (April to October). Bali, and in fact the whole Indonesian archipelago, experiences only slight temperature variations from season to season due to the warm ocean currents that keep heat fairly constant on land. There is also very little variation in daylight hours from season to season.
The dry season has hotter temperatures, but the humidity levels are much higher during the rainy season. The height of the summer season also brings cool breezes to temper the hot weather. Temperatures are cooler in the mountainous areas and it is less humid. The average annual temperature is about 86F (30C). Although it is generally better to travel to Indonesia in the dry season between April and October, Bali is one of the best islands to visit if tourists are travelling in the rainy monsoon season, as it experiences fewer weather-related travel disruptions and less flooding than many other islands. Even when it is rainy there will often be sunshine to enjoy on a daily basis. May, June and July are generally considered the best months to visit Bali.
