Jakarta sits near the equator and is warm year-round, but flooding and rainfall make timing important. June through September is the dry season and the best time to visit. Temperatures range from 26C to 32C, and the risk of the flooding that can paralyze the city is lowest. The Kota Tua (Old Batavia) area, Ancol Bay, and city parks are most accessible during dry months. October and November mark the transition into the wet season, with increasing afternoon showers. December through March is the wet season. January and February see the heaviest rainfall, and Jakarta's inadequate drainage system causes significant flooding in low-lying areas every few years. Even in the wet season, rain often falls in intense afternoon bursts rather than all day. Avoid the areas around the Ciliwung and Cilincing rivers during heavy rain alerts. The Indonesian Independence Day celebration on August 17 fills Jakarta with national pride events and street celebrations across all districts.
