Bali Climate Facts
Bali is located about 8 degrees south of the equator. Therefore you can expect a tropical, warm and humid climate all year round - with two main distinctive seasons: Dry Season and Rainy Season. Bali's central mountains (volcanoes) include several peaks over 3,000 meters in elevation. Up there, the temperatures are considerably cooler, and there is much more rainfall than in the coastal areas.
Best Time to visit Bali
Best time to visit Bali depends mainly on the weather and on high and low season, which does affect the overall price for accommodation. High season is during the months of July and August, during Easter Holidays, and Christmas / New Year (December till 1st week of January). This is the time Bali is the busiest. However, for many reasons, the best time to come to Bali is April, May, June and September, just before and just after high season. It's still dry season, it's slightly less humid, and room prices and villa rentals can be 30-50% cheaper than during the high season. Many shops offer sales and promotions, restaurants are less crowded in those mid-season months, and in general, Bali is a bit more relaxed. October is not too bad either, still much less rain than November (usually, check the rainfall chart). Those months are also the best time for water sport activities such as scuba diving, surfing, snorkeling, etc. Waters are clear, crowd not too bad, etc. Also, major activities and attractions such as the family parks and fun things to do (Bali Zoo, Bali Bird Park, Marine & Safari Park, Waterbom, White Water Rafting, Monkey Forest, etc) have fewer visitors which can make the experience far more enjoyable. If you wish to explore the island and visit the main sightseeing spots, temples and go for a day trip and tour, then those months are also perfect. And not to forget, in general, the traffic and hustle bustle on the roads is more bearable. Especially in Kuta, Legian and sometimes even Seminyak the narrow streets are packed during certain times in the day with cars and motorcycles. Some tourists love it that way and could not imagine a holiday otherwise, but if you like it quieter, then Kuta and Legian during the high season might not be the best choice.

Seasons and Temperatures on Bali
Dry Season is High Season
The dry season is between April and September. Bali receives the most visitors during July & August. Temperatures are pretty steady all year round. During Bali's dry season beaches are generally clean and Bali shows its pretty side. One can still expect occasional rainfall though, sometimes even the locals are surprised how dry a week during the rainy season can be and the other way around. Have a look at the chart below and check out temperatures, no. of days with rainfall etc in the capital Denpasar (south Bali near Kuta, Seminyak, etc).
During rainy season which is typically from October to March Bali becomes quieter. The sea is rougher, the beaches and the sea in the south (Kuta, Legian, Seminyak) can be quite dirty due to debris washed onto the shore during January and February. It's not happening always, but it can happen and depends on wind conditions and currents. During rainy season winds are stronger at the coast, the water currents pick up and it can rain in buckets. Although, usually the rain stops after a few hours and the sun shines again. A lot of the times it rains during the night and days are o.k. Very rarely you have a few days when it rains continuously. In 2014 it didn't rain in Bali till December! And November was as dry as any July or August. Like in all parts of the world, the weather becomes more unpredictable.
Central Bali and the Mountains
Bali's central mountain area is typically cooler and also rainier than the lower coastal areas. Especially at night temperatures can drop significantly in the highlands near the volcanoes. Gunung Agung is for example 3031m high! Also, the region around Ubud is a slightly cooler and expects more rain than the southern areas of Bali (Kuta, Legian, Seminyak, Denpasar, Sanur, Bukit Peninsula, Pecatu), which makes it rather pleasant.
General Climate - all year round
Bali's is located very near to the equator, therefore it's warm, tropical climate makes it a huge draw for tourists. Average year-round temperature stands at around 26-27°C with a humidity level of about 85-90%. Water temperatures are always pleasant. The two seasons are not clear cut and fully predictable. Christmas and New Year is clearly high / peak season on Bali and tourists come from all over the world to enjoy the beaches, the surfing, diving, the restaurants, the club, the spas and everything else Bali has to offer - although it is technically "rainy season". One can do everything during the wet season but climb the volcanoes and trekking in the highlands. Of course, it is more pleasant when the sun shines and also more fun while exploring the island.
Although the average numbers are based on many decades of data recording, today it seems less and less possible to count on those stats and give a solid prediction. November 2014 and 2015 where really dry and hot, while those are the months we expect the most rainfall. So in a way, it's a bit of luck too and you can expect either way.
