What to Wear in Cape Town in April
Packing for Cape Town in April means dressing for 18°C days and 9°C evenings. A mid-weight jacket over a sweater handles 18°C daytime temperatures; the combination stays comfortable all day without overheating. Evening temperatures settle at 9°C, a modest 9°C drop that a light cardigan or denim jacket covers.

Temperatures averaging 18°C by day and 9°C overnight are still comfortable by most standards, but the trend is clearly downward.
