Country Information

There are 3 time zones in Indonesia from UTC+7 to UTC+9.

There are around 580 languages and dialects in use in Indonesia, but Bahasa Indonesian is the official language. English is widely spoken, in all the major touristic destinations. Indonesia is a predominantly muslim country. Though very relaxed, travellers should still be respectful of the culture by covering legs and shoulders when in towns or visiting religious buildings.

Officially Indonesian Rupiah (IDR), however U$D is the most widely used. The Rupiah can be purchased from all major banks and exchange outlets. Credit and debit cards are also accepted in major hotels, restaurants & shops. ATM machines are plentiful around the airports, resort areas and ports.

Indonesia has excellent mobile phone coverage and telephone system, however, in less populated areas; you may find that there is no mobile coverage.

Indonesia’s climate is tropical. There is no autumn or winter but there are distinctive wet and dry seasons each year. The East Monsoon, from June to September, brings dry weather while the West Monsoon, from December to March is moisture-laden, bringing rain. Temperatures range from 21°C – 33°C, except at higher altitudes which can be much cooler. Heaviest rainfalls are usually recorded in December and January and humidity is generally between 75% and 100%.

Health services in Indonesia are by no means up to western standards, although there are hospitals in all major towns.

For diving related emergencies there are recompression chambers in both Bali and Manado. Reaching either would require air evacuation from the Indo Siren thus diving specific insurance is a must on any liveaboard dive trip.
