Warm but pleasant conditions in Sosan in June. Focus on lightweight, maybe with natural fabrics, cotton blend shirts, comfortable shorts, and breathable footwear. A light cover-up for sun protection is smart too. Expect heavy rainfall, so bring good rain protection and waterproof bags. Expect water temperatures of around 18°C (64°F), which is definitely too cold for comfortable swimming. Your luggage space is better used for other items. And with plenty of sunshine hours, don’t forget sunglasses, sunscreen, and maybe a sun hat.
