Perfect weather is subjective. On this map perfect weather has been defined with temperatures between 20°C (68°F) and 29°C (84°F) and not too much precipitation (less than 90 mm (3.5 in) a month).
Warm weather calls for comfortable, breathable clothing in May. Cotton t-shirts, shorts, light dresses, and sandals are perfect. You might still want a light layer for evenings or air-conditioned places (for example buses). High rain levels are expected, so pack waterproof gear and an umbrella or poncho. Expect water temperatures of around 26°C (79°F), which is ideal for taking a refreshing dip. Bring swimwear and consider packing a towel for drying off. And with plenty of sunshine hours, don’t forget sunglasses, sunscreen, and maybe a sun hat.
