When planning a trip to Zakynthos in the warm months, from May to October, the foundation of your wardrobe should consist of light and breathable items. Pack cotton T-shirts, shorts, sundresses, and, of course, several swimsuits to enjoy the famous beaches. Given the hot sun, especially from June to August when there is practically no rainfall, high SPF sunscreen, a wide-brimmed hat, and high-quality sunglasses are not just accessories, but necessities. For walking along picturesque streets and exploring the island, bring comfortable footwear, such as sandals or light trainers, and for evenings, especially in May or September, a light cardigan or shawl will come in handy.

If your journey falls during the period from November to March, it is worth preparing for cooler and wetter weather. At this time of year, Zakynthos receives the highest amount of rainfall, so a key element of your luggage will be a waterproof and windproof jacket. Layering is your best friend: combine T-shirts with jumpers, fleece jackets, or sweaters to easily adapt to temperature changes throughout the day. Don't forget an umbrella and comfortable closed-toe shoes to protect your feet from moisture during walks. Despite the rains, winter on the island remains mild, but the right clothing will make your stay comfortable.
