Best Time to Visit Indonesia
Indonesia is an archipelago country with thousands islands. Hundreds different ethnic groups and languages, hundreds different cultures and customs. This nation is united by a national laguage called “Bahasa Indonesia” which was declared in 1928 in “Youth Declaration”. The declaration is: one nation, one national language, Indonesia! Here are some important notes about the best time to visit Indonesia in each big islands.
The best time of year to visit the island of Java is during dry season which spans from May to September, when days are hot, dry and sunny. These months are also an ideal time to travel if you are planning on climbing the mountains of Bromo or Ijen.
Rainy season in Java runs from November to March, although East Java experiences less rainfall than the western regions. Days are characterized by regular, intense rain showers that tend to last for a couple of hours.
Temperatures are consistently warm year round, with average daily temperatures hovering around 28-30°C, although temperatures are cooler in the higher mountainous regions such as Mt Bromo, especially at night.
Bali’s dry season spans from April to September, with days characterized by blue skies and sunshine. The months of May, June and September are arguably the best time to visit, when the weather conditions are idyllic but visitor numbers are not at their highest, meaning the popular beach resorts of Jimbaran, Sanur and Seminyak are not too crowded.
Bali’s wet season falls between October and March, but we’re talking brief tropical rainfall rather than days of monsoonal downpours. Temperatures in Bali are fairly consistent year round, ranging from 26°C – 29°C, although the central regions around Ubud and the mountains, such as Mt Batur, experience cooler temperatures and higher rainfall than the coastal regions.
The islands of Nusa Tenggara, including Lombok & the Gili Islands, Flores & Sumba, typically experience dry season between April and September with plenty of sunshine and blue skies. These months are an ideal time to travel if you are planning to climb Mt Rinjani or dive off the coast of Lombok, the Gili Islands and in the Komodo National Park. Wet season falls between October and March, with November, December and January seeing the most rainfall.
Like the neighboring island of Bali, the average temperature is fairly consistent year round across the Nusa Tenggara islands, ranging from 27-29°C.
Sumatra is a fairly large island, split by the equator and weather conditions vary slightly across the island. Medan and North Sumatra experiences a more tropical climate with the possibility of rain showers year round, especially in the jungle-clad areas such as Bukit Lawang. The heaviest rainfall in the north is typically between October and January. Palembang and South Sumatra experiences a more definite split between wet and dry season, with drier weather typically occurring between April and October and rainfall from November to March. Average temperatures hover around 27-28°C throughout the year, although highs of 33-34°C are not uncommon during the drier, summer months.
Sulawesi, with its peculiar shape, experiences different weather conditions depending on where you are on the island. In Toraja and the southern part of the island monsoon rains fall between November & April; whilst the city of Manado and the northern regions experience rainfall year round, with the driest months between July & October. Temperature-wise it can get very stuffy on the coast, with highs of 34°C, dropping to a positively brisk 24°C in the hills of central Sulawesi.
Kalimantan is a large island and weather conditions vary slightly across the island, with the southern regions being the driest and the rainforest-covered interior predictably the wettest.
The island experiences a light rainy season from March to May, with heavier rains falling between November and January. However, overall the rains on Kalimantan tend to be lower than neighboring parts of Indonesia, such as the island of Java. Dry season spans from June until September, with August and September being the driest months of the year. Orang-utans can be spotted in the Tanjung Puting National Park throughout the year, although during rainy season they tend to be more elusive, preferring to shelter.
The temperature ranges from a warm 23°C at night to a hot 33°C during the day, with the hottest months typically May and August.
