Spring and autumn in this Croatian city can be changeable, so the principle of layering works ideally here. In the off-season, especially in May, the number of rainy days increases, so a compact umbrella or a quality raincoat are mandatory items on your packing list.

For a trip in December or January, you will need a warm windproof jacket or down coat, as well as a cozy scarf, gloves, and a hat. Pay special attention to footwear: it should be warm and preferably waterproof, as high humidity and frequent precipitation (about 11 rainy days per month) can create dampness. The right gear will allow you to enjoy the city's winter atmosphere with comfort.
