If you're planning outdoor activities in Jakarta, the wet season dictates everything. I tried running along the coast in January — 31°C, 85% humidity, and a thunderstorm hit at 3pm like clockwork. The data confirms: November-March brings 300mm monthly with afternoon storms. The dry season (June-September) is the only sane outdoor window: 31°C but humidity drops to 70% and rain halves. UV hits 11+ year-round between 10am-2pm — avoid direct sun. Flooding is a real risk January-February; check local conditions before any outdoor plan. Hydrate constantly; the equatorial heat sneaks up on you even on cloudy days.
