If you’re visiting during the wet season, packing a lightweight rain jacket and waterproof footwear will help you navigate the occasional deluge while still enjoying the town’s charm.

For a trip to Хойан during the dry season, lightweight, breathable clothing is essential. Opt for loose-fitting shirts, shorts, and dresses to stay comfortable in the heat, along with a wide-brimmed hat and sunglasses for sun protection.

During the rainy season, waterproof gear becomes a priority. A compact umbrella or a rain poncho will help you stay dry during sudden downpours, while quick-drying clothes and sandals with good grip are practical for navigating wet streets. Mosquito repellent is also useful, as humidity and standing water can increase insect activity. For those visiting in October or November, a light sweater may come in handy for cooler, rainier days.
