  4. Holidays in Indonesia in the summer: climate, what to do, where to stay

Indonesia is the world's largest island nation, which occupies most of the Malay Archipelago and is washed by two oceans at once - the Indian and the Pacific. Indonesia consists of about 17 thousand islands. In view of the location, the weather in different parts of the Indonesian land in one season can differ by several degrees. Humidity levels are predominantly high during the winter months, especially in regions with dense tropical forests. By the way, in Indonesia there are no four seasons familiar to Europeans. Conventionally, on the islands separated by the equator, there are only two seasons - wet and dry, with an average temperature of 21...33°C warm. Why is it worth vacationing in Indonesia in the summer? What to look for and which month to choose? We'll figure it out later in the article.

Choose and book hotels in Indonesia.


Climate of Indonesia

Summer weather on the tropical islands of Indonesia is slightly cooler than winter. The air temperature reaches 29...30°C during the day and 22...23°C at night. This is a couple of degrees lower than in winter. Large islands such as Sumatra, Borneo, Sulawesi, the Moluccas are characterized by dense jungle and a subequatorial climate with more rare "dry" days. At any time of the year it is usually humid and hot here.

Beach tourists are often interested in the question of the optimal season in Bali. During the summer months, a drier equatorial-monsoon climate prevails here.


Indonesia in summer season

May. May weather in Indonesia is the most summery. There are no intense rains, and the air temperature is kept at around 31...32°C. Exceptions for precipitation are found only in the always wet Sumatra.

June. Compared to early spring, the air temperature drops by 1-2 degrees. During the daytime around 30°C, at night - 22...23°C. At the same time, the water temperature remains at around 28...29°C.

July. In the middle of the dry season, the average air temperature in the islands of Indonesia rises to 32°C. Frequent rains during this period are characteristic of Sumatra. On the resort islands, beach holidays, diving and travel are in full swing.

August. By the end of the calendar summer, Indonesia still has a dry season with a minimum of precipitation. The water in the ocean is warmed up to 28°C, and the conditions are ideal for both sea holidays and travel.

September. With the onset of September, the weather in some places may not change for the better. If on the hotter islands the daily air temperature is still within 32...33°C, then in Sumatra, for example, it drops by 3-4 degrees. Increasingly, there are intermittent rains, which, by the way, are not a good reason for canceling trips.


Weather in Bali in summer

Summer in Bali and neighboring small islands, including Lombok, is the height of the season. Everything is as hot as in the second half of the year, but there is no such obsessive stuffiness. The air temperature is kept at around 28...29°C during the daytime, and the evenings are even a little cool.

The thing is that Bali successfully mixes holidays at seaside resorts with ecotours to natural places and temples of the island. There are tourist sites here that are best seen in the summer, so as not to change plans due to the frequent rains of the wet season. During your summer vacation in Bali, you won't have time for boredom.

Excursions in Bali in summer

  • Climbing Mount Agung. Climbing to the top of the highest volcano in Bali will be your most memorable trip. The height of Agung is 3142 meters. Not the easiest trekking route, but worth it. From the top, all the beauty of Bali opens up. It is better to climb in the summer, as it is less likely to get on an excursion in the rain, because on a cloudy and rainy day the view is not the most beautiful. Climbing is allowed only with guides. Usually up to 5 people are recruited for the tour.
  • Sunrise on top of Batur. Batur is now an active, second largest volcano in Bali. It offers a relatively short (about 2 hours) but productive climb. At dawn, the calderas are filled with a pinkish haze that creates an ethereal landscape. At the top there is a 7-kilometer lake Batur. During the sightseeing tour, the guides offer an exclusive lunch cooked inside the crater on volcanic steam.
  • Cultural heritage of Ubud. Summer will be the best period for walking around the most colorful city of Bali. Ubud is considered the spiritual heart of the island. Temples, yoga and meditation centers are concentrated here. The city is surrounded by hills, rice fields and deep gorges. Around Ubud there is where to roam, hiding from the sweltering heat.

The most suitable period for traveling to Bali is May and September.
