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).
Pleasant temperatures in August mean you can pack light but flexibel pieces. Think cotton t-shirts, comfortable walking shorts, and one warmer layer for evenings. A light sweater or denim jacket works well. Rain gear is recommended, you can expect wet weather on multiple days. Expect water temperatures of around 16°C (61°F), which is definitely too cold for comfortable swimming. Your luggage space is better used for other items. You'll definitely want to pack sunglasses and sunscreen. There will be plenty of bright sunshine this month.
