The "wettest" period, based on the frequency of bad weather, is winter: in December and January, precipitation can be observed up to 19–20 days per month.

Even in summer, when average temperatures stay around 19°C, evenings can be cool, so a light sweater or windbreaker will be handy. In winter, despite the lack of severe frosts (average temperature around 4-5°C), high humidity can create a piercing cold sensation, so be sure to bring a warm jacket, scarf, and gloves.

Pay special attention to rain protection: statistics show that rainy days occur frequently throughout the year — from 11 to 20 days per month. A compact, sturdy umbrella or a high-quality raincoat will be your best friends during your walks. Since city sightseeing involves long walks, pack comfortable, preferably waterproof flat shoes suitable for walking on cobblestones and asphalt.

In summer, when the air warms up to a comfortable 23-24°C, opt for clothing made from natural breathable fabrics such as cotton or linen. Don't forget sunscreen and a hat, as sunny days are ideal for excursions. During the shoulder seasons, the weather can change quickly from sunny to overcast, so a versatile wardrobe that allows you to easily add or remove layers will ensure your comfort in any situation.
