For the warm season, especially from December to March, choose light, breathable clothing made from natural fabrics, such as T-shirts, shorts, and light dresses. Do not forget sunscreen, a hat, and sunglasses for sun protection. In the cooler months, from June to August, and during the shoulder seasons when evenings can be fresh, you will need warm items: sweaters, fleece jackets, jeans or thick trousers, as well as a mid-season or light winter jacket. Even in the relatively dry winter months, it is worth having something to protect against potential rain. It is always useful to check the current weather forecast before heading out to be ready for any changes.
