What should I pack for a holiday in Santorini in September?
The great weather in Santorini at this time of year means that this will feel like a summer holiday. So, pack loose-fitting, light clothing to cope with the soaring daytime temperatures. Ladies should take sun dresses, shorts and kaftans for exploring the caldera villages and lounging on the beach. For men, shorts and shirts will do the trick wherever you go on the island. Sunhats and sunglasses are also an essential part of your holiday wardrobe for Santorini. If you plan on hiking on any of the island trails, then comfortable outdoor footwear is a must as the terrain is often uneven. Remember to pack a jumper or light jacket for potentially cooler evenings.
