Bahasa Indonesia is the national and official language of Indonesia and is used in the entire country. Most Indonesians also have their own ethnic language and dialect, with the most widely spoken being Javanese and Sundanese. Some ethnic Chinese communities continue to speak various Chinese dialects, most notably Hokkien in Medan and Teochew in Pontianak.

English is not widely spoken in Indonesia. However, an acceptable level of English can be understood in a number of major cities and tourists’ destinations including Bali, Batam, Jakarta, Bandung, Surabaya, and Yogyakarta. Moreover, most hotel and airline staff can also communicate in English on a basic to moderate level. All of our guides/drivers can also speak English.

You can exchange foreign currency in major cities throughout the archipelago at banks and money changers. Most tourists’ resorts have money changer facilities; however, if you are traveling to more remote areas it is advisable to exchange your money beforehand. If you need a large amount of foreign currency, and you don’t have a foreign currency account at your bank, it is best to order the money the day before. Local banks keep a limited amount of foreign currency in their smaller branches.

The climate of Indonesia is almost entirely tropical. The uniformly warm waters that make up 81% of Indonesia’s area ensures that temperatures on land remain fairly constant, with the coastal plains averaging 28 °C, the inland and mountain areas averaging 26 °C, and the higher mountain regions, 23 °C. Temperature varies little from season to season, and Indonesia experiences relatively little change in the length of daylight hours from one season to the next.

The main variable of Indonesia’s climate is not temperature or air pressure, but rainfall. The area’s relative humidity ranges between 70% and 90%. Although air temperature changes little from season to season or from one region to the next, cooler temperatures prevail at higher elevations. In general, temperatures drop approximately 1°C per 90-meter increase in elevation from sea level with some high-altitude interior mountain regions experiencing night frosts.

Being a tropical country, Indonesia does not have spring, summer, autumn, or winter, instead of just the two seasons of Rainy and Dry, both of which are relative. While there is significant regional variation, in most of the country (including Java and Bali) the dry season is March to October, while the wet season is November to February. However, global warming has made the seasons less predictable.

Most hotels add a 10% service charge to the bill on top of the 10% tax. In restaurants where service charge is not added, a tip of 5 to 10% on the bill will be appropriate depending on the service and type of establishment.
