Why Santorini Is a Summer Favorite

Santorini is not just another island - it’s a romantic, dramatic caldera built by volcanic activity thousands of years ago. Few places in Greece offer the combination of volcanic landscapes, luxury stays, and history that Santorini delivers.

Here’s what makes Santorini in summer truly special:

• Warm, sunny weather (May to September)
• Unique volcanic beaches (black, red, and golden sands!)
• World-famous sunsets over the Aegean
• Rich history and archeological sites
• Flavor-packed Greek cuisine and excellent local wines

If you're planning a summer getaway, Santorini is a dream destination - but it pays to plan wisely to avoid crowds and maximize your experience.

When to Visit Santorini in Summer

High season in Santorini runs from mid-June through early September. Here’s how the summer months break down:

• May to early June: Warm, pleasant, and less crowded - perfect for photographers and explorers.
• Mid-June to August: Peak season. The island is buzzing, but prices are high and crowds are thick.
• September: Still summery but with thinner crowds and slightly cooler evenings.

If you want a great balance of good weather and fewer people, aim for late May or early September.

Where to Stay in Santorini

Each town in Santorini has its own personality, and where you stay can shape your experience:

Oia – The Icon

Famous for sunsets and romance, Oia is the most photographed place on the island. Expect luxury hotels, boutique shops, and cliffside restaurants. It’s beautiful, but pricey and often packed with people.

Fira – Central and Social

Fira is the capital and main transport hub. It’s great for easy access to tours, nightlife, and shops. More budget-friendly than Oia, but still very lively.

Imerovigli – Quiet and Upscale

Want the sunset without the crowds? Stay in Imerovigli. Imerovigli offers tranquility, elegance, and uninterrupted sunsets. Ideal for couples.

Perissa or Kamari – Beach Towns

These towns are located on the coast and are perfect for laid-back beach days. They’re more relaxed, affordable, and still have plenty of dining and entertainment options.

Must-Do Experiences: Things to Do in Santorini in Summer

Looking for unforgettable memories? These are the top things to do in Santorini in summer:

1. Watch the Sunset in Oia

Yes, it's cliché and yes, it’s crowded. But there’s nothing quite like watching the sun dip below the Aegean from Oia. Arrive early to claim a spot near the castle ruins or book a rooftop dinner.

2. Take a Caldera Boat Tour

Sailing across the volcanic caldera is one of the best ways to see Santorini. Most tours include stops at hot springs, snorkeling spots, sunset views, and onboard BBQ dinners.

3. Explore the Beaches

Santorini's beaches are unique thanks to their volcanic origin. Don’t miss:

• Red Beach – Surreal red cliffs and dark sand
• Kamari Beach – A lively black sand beach with loungers and bars
• Perissa Beach – Great for families and water sports

4. Visit the Akrotiri Archaeological Site

This ancient city was buried by a volcanic eruption around 1600 BC. Often referred to as the "Greek Pompeii," it gives a fascinating glimpse into prehistoric Aegean life.

5. Hike from Fira to Oia

A scenic cliffside hike taking about 2–3 hours. Go early in the day or just before sunset. You’ll pass whitewashed churches, rocky trails, and breathtaking caldera views.

Local Food and Wine You Have to Try

Greek food is an essential part of the experience, and Santorini serves up some of the freshest and most flavorful dishes in the country.

Must-Try Dishes

• Tomatokeftedes – Fried tomato fritters
• Fava – Creamy yellow split peas served with olive oil
• White eggplant – Sweeter and softer than the purple variety
• Fresh seafood – Grilled octopus, calamari, and whole fish are everywhere

Wines to Sample

• Assyrtiko – A crisp white wine grown in volcanic soil
• Vinsanto – A naturally sweet dessert wine perfect with local cheeses

Don't miss a sunset wine tasting tour or a visit to a local vineyard.

Getting Around the Island

Getting from beach to village or viewpoint to vineyard is part of the adventure. Here are your main transport options:

• Public buses – Reliable and cheap, especially between major towns
• ATV rentals – Fun and flexible, perfect for adventurous duos
• Taxis – Limited and expensive, best to book in advance
• Private transfers – Convenient for hotel and airport transfers
