Indonesia is the largest archipelago in the world with over 15,000 islands ranging in size from hundreds of kilometres across to tiny palm fringed atolls. It sits astride the Equator in South East Asia stretching over 5,000 kilometres (3,200 miles) from the Indian Ocean to the Pacific, further than the distance from Los Angeles to New York.
With its rich cultural heritage and diverse population Indonesia offers travellers an enormous variety of destinations and holiday experiences. Apart from spectacular mountain volcanoes, deep tropical rainforest and miles of white sandy beaches there is history, architecture, music, dance and traditional crafts.
Indonesia is the fourth most populated country in the world and over half the 240 million population lives on the relatively small island of Java, making this the most densely populated place on earth.
The vegetation throughout the country is tropical with large areas of rainforest still standing on the islands of Sumatra, Borneo, and New Guinea. Much of the original forest on Java has been cleared for cultivation, mainly for rice, however areas of wilderness can still be found such as at the Ujung Kulon National Park in the west.
Sumatra and Borneo are much wilder than Java although increasing tracts of forest are now being cleared for rubber and palm oil plantations. Western New Guinea on the other hand is very remote and contains some of the most inaccessible places on earth.
A chain of volcanic mountains stretches down the western side of Sumatra, extending to Java and Bali and through the islands of Nusa Tenggara to the east. Within this chain there are about 70 active volcanoes, most of which have erupted at some time in the past 100 years.
Lake Toba in Northern Sumatra was the scene of a mega-volcanic eruption 72,000 years ago which, it is estimated, killed most of the inhabitants of South East Asia, while the eruption of Krakatoa in 1883, though tiny by comparison, is still one of the largest in recorded history.
There are only two types of weather in Indonesia, fine and sunny or cloudy and wet. Temperatures are fairly constant throughout the year and depend mainly on elevation above sea level, while heat and humidity is high in all months. All the islands lie outside the tropical cyclone belt although some in the extreme south, such as Timor and Sumba, are occasionally affected by cyclones.
The wet season arrives in November on the north-west monsoon which blows until March bringing rain from the Indian Ocean to most of the country. Usually during this time the further west and north you are the more rain there is. However there is generally also a fair amount of sunshine during the wet season almost everywhere except in the mountains. In Bali for example, in the south of the island, there will be on average 8 hours of sunshine each day during December, January and February.
Generally drier weather conditions prevail during the south-east monsoon period from June to September especially over the islands nearest to Australia which includes Java and Bali and Lombok.
Daytime temperatures are only a degree or so cooler than during the wet season, but there is noticeably less heat and humidity at night. Unusually the central islands of the Moluccas, with destinations such as Ambon and Banda, experience their wet season during this time.
Indonesia is one of the most active volcanic and seismic areas in the world with earthquakes recorded almost every day and more volcanic eruptions than any other region in the world. The northern part of Sumatra, particularly the Aceh region, was hit hard by the Asian Tsunami of December 2004. Tens of thousands of lives were lost, and damage was extensive.
