Choosing the right part of the year in Jakarta
Choose dates by rain, not just temperature
Aim for July to October if you get the choice: humidity and rainfall are at their lowest, which is what actually varies here, and highs average 90°F (32°C) against roughly 15 wet days a month. For the same question asked the other way round, see where else is warm in July.
What the humidity changes
Pack for Jakarta with lightweight, breathable clothing and serious sun protection, proper waterproofs rather than an umbrella - wet days are the norm here and moisture-wicking fabrics for the humidity. September nights average 75°F (24°C), so evenings rarely match the afternoons.
