Lying across the Equator, DRC has an equatorial climate in the whole of the central region. Average temperatures range from 26 degrees C in the coastal and basin areas to 18 degrees C in the mountainous regions.
Rainfall is plentiful in all seasons.
The country comprises, first and foremost, the basin of the River Congo. The climate is generally favourable for agriculture and woodland. Evergreen equatorial forest covers approximately 1m. sq km in the equatorial and sub-equatorial parts. In the north as in the south of this evergreen forest, tropical forests appear, with many trees that lose their leaves in the dry season. Although favourable on account of its warmth and rainfall, the climate has a few unfortunate indirect effects.
