Bali is an Indonesian island lying just about 8 degrees south of the equator. Therefore it has a tropical, hot climate all year round, with a rainy season running from November to March and a dry season running from April to October, when, however, some rainfalls can still occur during the day.
The number of daylight hours is always about the same and averages 12 hours. The sun rises at around 6 a.m. and sets at around 6 p.m.
The water temperature in Bali is enjoyable for swimming at any time of the year and ranges from 27ºC between July and September, to 29ºC between November and May.
With regard to air temperature, the daily average is 27ºC and can reach 32ºC in coastal areas. At night, the temperature can drop up to 19ºC.
Northwards, in hilly and mountainous areas of Bali, the weather can be more cloudy and rainy. Rain-showers and thunderstorms are more likely than on the southern coast. Evenings are a bit chilly and it can get quite cold at night, especially during the dry seasons.
The dry season in Bali is characterized by warm temperatures without too much precipitation, and by lower humidity levels. Bright clear weather during the day is comfortable for sunbathing, and a pleasant cool breeze in the evening is ideal for making a promenade along the coastline. This is a great time for outdoor activities such as trekking through spectacular rice paddies, hiking through tropical jungles to hidden waterfalls, climbing a volcano, cycling or surfing along Bali’s famous west coast.
Even during the rainy season, Bali is an amazing place for having a holiday. Swimming, sunbathing, surfing, sightseeing… all these holiday activities are still pleasurable in the wet season as well. Though you should take into consideration that this season implies some specifics. Throughout the rainy season you can expect more humidity, cloudiness, and heavy rainfalls, often of short duration. The rainiest months are December and January. Be sure that even in cloudy weather it’s impossible to get bored, as there are so many pastime options that Bali can offer you. For example, you can visit a luxury spa, sign up for a yoga class, go to a cooking class to learn how to recreate some traditional Balinese dishes, and much more.
