The Palmiet River has a Mediterranean climate receiving most of its rainfall in winter from about May to September and is characterised by a warm to hot and dry summer.  (Ref 2)

Summer:   Hot, dry and often very windy.

During the summer months south-easterly to easterly winds predominate. (Ref 2)

Winters: Cold and very wet, and snow may fall on the higher peaks.

During the winter months north to north-westerly winds prevail. (Ref 2)

    RAINFALL                                    
Rainfall:  The winter rainfall in the Palmiet catchment area is associated with westerly cyclones which move over the south-western Cape.  

Orographic rainfall also occurs, the mountainous regions receiving more rain than the valleys.

Rainfall varies from about 700mm per year in the low-lying central, eastern and coastal region to ca. 1500 mm inland.

Highest average monthly rainfall generally occurs between June and August whereas lowest monthly  average occur in December and January.  (Ref 2)
