More information on average rainfall and temperature for each of the climate zones in Libya can be seen at the Libya climate page.
These maps and graphs were developed from the CRU TS 3.21 dataset produced by the Climatic Research Unit at the University of East Anglia, UK. For more information see the climate resource page.
There are no permanent rivers in Libya, only ephemeral rivers or wadis. The main natural lakes are the Ubari lakes in the Ubari Sand Sea in the south, including the Gaberoun, Mandara and Mafo akes–, the protected Ouau en Namu lakes and the 23rd of July or Benghazi lake, which is actually a lagoon.
The Qattara Depression in the north-west of Libya lies under the sea level and is covered with temporary lakes, salt pans and salt marshes. Other large salt pans include Sabkhat al Hayshah close to the coast near the gulf of Sidra, and Sabkhat Shunayn and Ghuzayyil in the north-east.
The geology map on this page shows a simplified version of the geology at a national scale (see the Geology resource page for more details).
The hydrogeology map below, at 1:5 million scale, shows the type and productivity of the main aquifers at a national scale (see the Hydrogeology map resource page for more details).
More information on the hydrogeology of Libya is available in the report United Nations (1988) (see References section, below).
