The principle of layering your clothes is ideal for these seasons. Bring T-shirts, long-sleeved shirts, sweaters or fleece jackets, as well as a windbreaker or a mid-season jacket. Although the total precipitation is low (1-2 mm per month), the number of days with potential rain increases from May to November (up to 10 days in July), so a lightweight waterproof jacket or a compact umbrella can be very handy.

Given the significant temperature drops between day and night, especially in the summer and shoulder months, having several layers of clothing will allow you to easily adapt to changing conditions and stay comfortable throughout your trip.
