What to pack
For a trip to Cape St. Francis in summer (December to February), pack light, breathable clothing—think shorts, T-shirts, and sandals—along with a light jacket for cooler evenings. A wide-brimmed hat and sunscreen are essential, as the sun can be strong even when the breeze is up. If you plan to swim, a rash vest will help protect against the wind-chill in the water, which averages 19–20 °C.
In the cooler months (June to August), layers are key. Mornings and evenings can feel crisp, especially near the water, so a fleece or light sweater is useful. Long pants and closed shoes will keep you comfortable during coastal walks, while a waterproof jacket is worth bringing for occasional showers. For spring (September to November) or autumn (March to May), a mix of light and mid-weight clothing will cover the mild but variable conditions.
