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).
Dress warmly and in layers for your trip to Ulchin in January. A good base layer system works wonders. Start with good thermal underwear, add something warm like a fleece sweater, then finish with a waterproof jacket on top. Wet weather is likely, so pack waterproof gear for multiple rainy days. With water temperatures around 9°C (48°F), the water is quite cold for swimming. You can skip the swimwear unless you're particularly tough. Don't forget sun protection, sunglasses, sunscreen, and a hat. These are all good ideas with this much sunshine.
