Indonesia water temperatures can be quite changeable, even during the same dive, ranging from the low to mid 70’s to the low 80 degrees Fahrenheit. You're going to love the scuba diving in Indonesia and will want to be ready for plenty of bottom time. Best plan is to bring a 3-5 mm wetsuit with some additional neoprene accessories, such as hood and gloves, that can be added or subtracted as needed.
