The dry season, from May to September, is characterized by minimal rainfall and lower humidity. Days remain warm, but evenings, especially in June and July, can be a bit cooler (minimum temperatures around 15-16°C), so a light sweater or cardigan would be very useful. The principle of layering clothing is not as critical here as in regions with sharp temperature changes, but having light outer clothing for evening walks during the dry season or for air-conditioned spaces will be helpful.
