of the island, occupied by hills and mountains, the weather is more likely to be cloudy and rainy. The highest peak is Agung volcano, 3,000 meters (9,800 feet) high. Being closer to the inland elevations, the northern coast is rainier than the southern one. The southern part of the island, where Denpasar is located, in addition to cities such as Ubud, Kuta, Seminyak and Pecatu, is therefore the least rainy. If you are planning some hiking at high altitudes, keep in mind that above 1,000 meters (3,300 feet), in towns such as Bedugul and Kintamani, it's cool in the evening and at night, especially in the dry season, while above 2,000 meters (6,500 feet) it can get quite cold. In addition, at noon and in the afternoon the chance of thunderstorms in the highlands is higher than on the southern side, where the majority of the resorts are found.

There are just some brief downpours or thunderstorms every now and then, which, however, are more likely at night and in the early morning. August is the best month, since it is the driest. May and October, too, are months you may want to consider, in fact they are the best ones among those that do not fall in the high season: they are a bit more muggy and rainy, but they are still out of the actual rainy season. However, in inland and mountainous areas, thunderstorms are frequent.
