In the spring (especially May) and autumn months, the weather can be unpredictable, so jeans or trousers, long-sleeve shirts, sweaters, and a mid-season jacket are best. Layering will allow you to easily adapt to temperature changes throughout the day.

You won't get by without a warm winter jacket or down coat, a hat, scarf, gloves, and insulated, preferably waterproof, footwear, as precipitation this time of year often falls as snow. Warm sweaters, fleece tops, and thermal underwear will help you stay warm while exploring the snowy landscapes of Montenegro.
