When planning a trip to Stellenbosch, it's important to consider its Mediterranean climate with distinct seasons, which influences your choice of wardrobe. Overall, you can expect warm, dry summers and mild, wetter winters. The principle of layering will be your best friend, allowing you to stay comfortable as temperatures change throughout the day.

If your trip falls during the summer months (December to February), when the average temperature is around 22-23°C and highs can reach 28-29°C, pack light and breathable clothing: t-shirts, shorts, sundresses, and swimwear. Don't forget a high SPF sunscreen, sunglasses, and a hat to protect yourself from the bright South African sun. While rainfall is minimal during this time, a light sweater or cardigan will be useful for evening strolls. In spring (September–November) and autumn (March–May), the weather is transitional: days are warm, but evenings can be cool. You'll need t-shirts, jeans or trousers, and a light jacket or sweater. In March–May, the number of rainy days increases slightly, so a compact umbrella or a light waterproof jacket may be useful.

Therefore, you should pack warm clothes: sweaters, a fleece, jeans, perhaps thermal underwear for those sensitive to the cold, as well as a waterproof jacket or coat and an umbrella. Closed-toe shoes, possibly waterproof, will also be very useful. A scarf and hat can add comfort on particularly cool or windy days. Layering is especially important in winter to adapt to the temperature difference between indoors and outdoors.
