• The catchment of Zandvlei extends furthest north to the source of the Diep River above the Kirstenbosch Botanical Gardens about 15kms away and then enters Zandvlei as the Sand River in the north east.

The average total annual rainfall is between 450 - 700mm.
• Zandvlei is rated in the top 25% in importance of all the estuaries along the South Africa coastline.
  It is 43 out of the total 256.
• At mid summer the sun angle is 79 degrees above the north horizon and mid winter it is 33 degrees. 
• Day time air temperatures can range from 40 to 5 C degrees in mid summer to mid winter. Mean seasonal average day temparature is 22 C degrees. Air temparature and wind strength does vary and is influenced by local geographical conditions. Humidity levels are low, due mainly to the prevailling cool winds from the sea, in south east and north west directions.
