Essentials for Santorini in May

Wide-Brimmed Hat
Protect yourself from the strong Aegean sun during your daytime adventures, especially when lounging by the pool or exploring archaeological sites.

With beautiful beaches and inviting hotel pools, you'll want multiple options to enjoy the refreshing water and allow one to dry while wearing another.
Lightweight Scarf or Pashmina
Perfect for adding a touch of elegance in the evening, providing a bit of warmth on breezy nights, or covering your shoulders when visiting religious sites.

Sunglasses (polarized recommended)
Protect your eyes from the bright glare off the white buildings and sparkling Aegean Sea.
Moisturizer with After-Sun Properties

Pro tips
Footwear is Key
Santorini is best explored on foot. Leave the high heels at home and pack stylish yet practical sandals or sneakers for navigating the caldera paths and charming villages.
Sun Protection is Non-Negotiable
The May sun is powerful. Always wear sunscreen, a hat, and sunglasses, especially between 11 AM and 3 PM, to avoid sunburn.
Book Excursions in Advance
May marks the start of the high season. If you have your heart set on a specific boat tour, wine tasting, or restaurant, make reservations ahead of time to avoid disappointment.
Stay Hydrated
Carry a reusable water bottle and drink plenty of water throughout the day. The warm weather means you'll be perspiring more than usual, even if you don't feel it.
