Jakarta weather shares the typically balmy and humid conditions that you would find throughout the Indonesian archipelago. Despite being only six degrees south of the equator that makes for sunny and tropical weather all year round, within and around the main city hub you’ll find concrete jungles with modern high-rising skyscrapers that shades urban dwellers from the sun most of the time.
Outside, temperatures range between 24-32.5 degrees Celsius throughout the year. It is a tropical monsoon here with a wet season featuring intermittent downpours between October and May, and a dry season with sunnier days from June to September. The city has a collection of highlights that are great to visit in any season, but some may prefer one time of the year over the other. Before your visit, read on for all you need to know about the weather in Jakarta.

Also, the fasting month of Ramadan is oftentimes considered the low season in Jakarta, the ninth month in the Islamic lunar calendar, which varyingly coincides between April and July each year, and culminates in a week-long holiday for Idul Fitri. Most business close and Muslim Jakarta residents from other areas in Indonesia go home for the holidays.
