Traveller notes on Stellenbosch in August
Other months in Stellenbosch
Stellenbosch's forum calls November one of the best months in the Western Cape — green and lush after the winter rains, the first genuinely summer-warm stretch of the year. Regulars flag it as more changeable than February, with more chance of rain, days that can reach 40°C alongside cooler ones, and a jumper worth having for evenings even though days need no warm layers.
