A wide-brimmed hat, sunglasses, and sunscreen are must-haves, as the sun is strong even in cooler months. Don’t forget a light rain jacket, as brief showers can occur even in the dry season.

During the wet season (May to October), waterproof footwear and a compact umbrella will help you navigate sudden downpours. Quick-drying clothes are ideal, as humidity can make fabrics feel damp. A light sweater may be useful for cooler evenings, though temperatures rarely drop below +24 °C.
