The table below ranks the sites from highest to lowest WFAR Annual Index.
Although Gabès and Gafsa are in the same climate zone (arid | desert | hot arid), water-from-air systems will perform better in the moister air of coastal Gabès.
The warm temperate climate of Tunis to the north has a more consistent water-from-air resource through the year than does the arid climate of Sfax to the south.
Tunisia's water-from-air resource exhibits considerable seasonal differences. On balance, the country is a reasonable choice for deployment of water-from-air systems.
