Best valueBusy and pricierQuietAverage temperature in Jakarta, °C, 2001–2025 (NASA POWER).

Each bar is the average temperature in Jakarta for that month, and its colour shows the season for visitors: best value (good weather, fewer crowds and lower prices), busiest and priciest, or quiet (off-peak, sometimes because the weather is poorer).

  • Our pick: April and SeptemberThe warmest of the best-value months (28°C), with fewer crowds than peak season.
  • Peak season: May–Aug, DecUsually 27–28°C. The busiest time, so book flights and rooms early and expect higher prices.
  • Quiet season: Oct–NovAround 28°C. The cheapest and least crowded time, though often because of rain or heat.
  • Warmest: October (28°C) · coolest: February (27°C)Temperatures barely change through the year, so the season matters more than the weather.
