Bali has a tropical monsoon climate. The island is situated close to the equator, which means it is always warm and there are only 2 seasons: a dry and a rainy season. The average temperature is pretty much the same all year around, although there is a difference between daytime and nighttime temperatures. The average daytime temperature is 28° C, at night the average is 22° C. The temperature of the sea water, around 28° C, is quite constant throughout the year.
The ‘dry’ season is from April until November. The rainy season is characterized by short, abundant rainfall during the months of November through April (the monsoon). However, also during the ‘dry’ months every now and then there will be a tropical downpour, but these are often short and fierce, and the sun will shine exuberantly again afterwards.
Like anywhere in the tropics most showers are either in the late afternoon or evening. The mornings are generally clear and sunny.
Due to the high humidity, the weather is often quite sultry. Most of the times the weather in the higher altitudes is cooler. Along the shore there is often a nice breeze, which makes the beach a pleasant place to stay.
