  • Longitude: 106.8° E
  • Elevation: Mostly at sea level

The proximity to the sea and flat terrain means that Jakarta does not have any significant hills or mountains. The city’s landscape is dominated by urban development, with dense infrastructure covering most of the area. The coastal and riverine geography plays a crucial role in Jakarta’s environmental and climatic conditions.
