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).
Cold weather calls for smart layering in December. A thermal base layer makes a huge difference in staying warm. Add a wool sweater or fleece, then a wind-resistant outer jacket. Heavy rain is guaranteed, please bring a good poncho and waterproof everything! Expect water temperatures of around 8°C (46°F), which is definitely too cold for comfortable swimming. Your luggage space is better used for other items. With limited sunshine expected, sunglasses aren't a priority for packing.
