When planning a trip to Leiria, first take care of your feet: the city is known for its hills and ancient cobblestones.

The clothing style here is casual and relaxed, so rely on practicality and comfort.

Summer in this region of Portugal is usually very pleasant and dry, with temperatures around +20–24°C, so for a trip from June to September, choose light clothing made from natural fabrics. Be sure to bring sunglasses, headwear, and high SPF cream, as the sun can be quite active. Despite the warm days, evenings can be refreshing, so a light cardigan or windbreaker will not be out of place in your luggage.

In the off-season and winter, especially from November to February, the weather becomes wetter and cooler, with frequent rains. During this period, you will definitely need a waterproof jacket with a hood, a sturdy umbrella, and warmer shoes. Since the temperature rarely drops below +8°C, heavy down jackets will not be required, but it is best to use the principle of layering: a combination of a t-shirt, a warm sweater, and moisture-proof outerwear will allow you to feel comfortable during any weather changes.
