Considering the frequent number of days with precipitation throughout the year, a compact umbrella or raincoat will be indispensable.

For a summer trip (June-August), pack light clothing: t-shirts, shorts, sundresses. Days are usually warm and sunny, but for evening walks or in case of rain, it is worth having a light cardigan or windbreaker with you. Don't forget sunscreen. In winter (December-February), the weather requires serious warm clothing. The temperature often drops below freezing, so a warm jacket, hat, scarf, and gloves are mandatory. Waterproof boots that protect against the cold and wet snow are best.
