Jakarta is a noisy and chaotic metropolis and there are cautions to be aware of as with any large urban center. While it can be a headache and the weather decidedly muggy, it can also be lots of fun if you know what you're doing. More on Jakarta travel tips.
Customs and etiquette
Indonesians are generally laid-back, yet there are some dos and don'ts to be aware of so as not to offend. Shoes should always be removed before entering temples, mosques, and even some shops. Ensure shorts and skirts cover the knees when in town, avoid pointing, and don't eat with your left (toilet duty) hand.
Also avoid smooching in public with your partner or local and keep any temper in check, even in the most trying of situations. Jakarta is not tip-heavy, although a gratuity at a non-service-charging restaurant and the rounding up of a cab bill is usually expected.
The local currency is the Indonesian rupiah (Rp), with notes ranging from Rp500 to Rp100,000 and coins of up to Rp1,000. Changing money at banks is the best bet, with hotels having the worst exchange rates.
Jakarta is fairly credit card-friendly, with shops, restaurants and hotels all generally accepting Visa and MasterCard. Beware of high ATM charges and remember cash is king in the inexpensive markets.
Jakarta's close proximity with the equator means that it remains hot year round, with little deviation in the seasonal sense. The monsoon season goes from October to February and is particularly wet, while June through September is generally boiling hot and the best time to visit is between March and June.
