Is May a Good Time to Visit Santorini?
Yes. May is one of the best months to visit Santorini, especially for a first trip. The weather is great for outdoor dining and sightseeing but cool enough for hiking. All hotels, restaurants, wineries, and boat tours are open, and hotel prices are lower than in summer. The main drawback is swimming: the sea is still cold, and many unheated hotel pools are too chilly to enjoy.
I’d choose the second half of May for most first-time visitors. The weather is warmer, beach restaurants are livelier, and the island has a nice hum without the crowds of July and August. Early May is better for hiking, spring scenery, lower hotel prices, and quieter villages. If swimming and beach clubs are your priorities, June or September is a better choice.
Santorini in May at a Glance
- Weather: Mostly sunny and mild, with typical afternoon temperatures around 20°C to 24°C (68°F to 75°F). Warmer days become more common toward the end of May.
- Evenings: Cool, especially along the caldera. Bring a light jacket or sweater.
- Swimming: Sea temperatures average around 19°C (66°F). Swimming is possible, but the water is cold for most visitors.
- Crowds: Fira and Oia are busy during cruise-ship visits, but May is much quieter than July and August.
- Hotel Prices: Lower than summer, though the best caldera hotels and private-pool suites are still expensive.
- What’s Open: All hotels, restaurants, wineries, and tours. Some seasonal beach businesses open later in the month.
- Best Activities: The Fira-to-Oia hike, wineries, caldera boat tours, village walks, and archaeological sites.
- Main Downside: Cold sea water and unheated hotel pools.
Early May vs. Late May
- Early May: Cooler, greener, quieter, and cheaper. Excellent for hiking, photography, and exploring Oia, Imerovigli, and the inland villages. Some beach restaurants and seasonal businesses are still opening. Evenings can be chilly.
- Mid May: All hotels, restaurants, wineries, and tours are operating. A good balance of comfortable temperatures and manageable crowds.
- Late May: Warmer days, more beach restaurants and sunbeds, and a livelier atmosphere. The sea is a little warmer, though still cool. Hotel prices increase as June approaches.
May Weather in Santorini
May is one of the best months for sightseeing in Santorini. Typical afternoon temperatures are around 20°C to 24°C (68°F to 75°F), with warmer days becoming more common later in the month. Sunshine is frequent, but rain is still possible, particularly in early May.
Evenings remain cool, especially on exposed caldera terraces and boat decks. Bring a jacket for sunset dinners and cruises. May is generally less windy than July and August, when the summer meltemi is strongest, but individual days can still be very windy.
The island is greener than in summer, particularly in early May, when wildflowers and spring vegetation can still be seen along hiking paths and around the inland villages. May is also a good month for photography, with fewer crowds than in peak summer.
Can You Swim in Santorini in May?
Yes, but the sea is cold. Water temperatures average around 19°C (66°F), with late May slightly warmer than early May. Swimming is possible on sunny days, but most visitors won’t want to stay in the water for long. September is much better for swimming, with sea temperatures still warm from summer.
Unheated hotel pools feel colder than expected, particularly when shaded or exposed to wind. If swimming at your hotel matters, book one of the Santorini hotels with a heated pool and ask what water temperature the hotel maintains during your dates. Some properties warm pools only a few degrees, while others keep them genuinely comfortable. Don’t assume a private plunge pool is heated.
What Is Open in Santorini in May?
Most of Santorini’s tourist businesses are operating by May. Fira, Firostefani, Imerovigli, and Oia have plenty of open hotels, restaurants, and shops throughout the month. Beach towns are quieter, particularly in early May.
- Hotels: All caldera hotels and resorts are open. Some smaller seasonal properties and beach hotels open during May rather than at the beginning of the month.
- Restaurants: Plenty of choices in Fira, Oia, Firostefani, Imerovigli, and Pyrgos. Beach restaurants in Kamari, Perissa, and Perivolos open progressively through the month.
- Boat Tours: Catamaran cruises, volcano tours, sunset trips, and private charters operate regularly, weather permitting.
- Wineries: All wineries and tasting rooms are open. May is an excellent time for outdoor wine tastings.
- Beach Clubs: Many beach restaurants and sunbed operators open during May, but don’t expect the full summer beach-club scene in early May.
- Attractions: Major museums and archaeological sites operate on seasonal schedules. Check opening days and hours for Ancient Akrotiri and Ancient Thera before visiting.
- Nightlife: Fira has bars and late-night venues throughout May. Beach nightlife becomes livelier toward June.
If Greek Easter falls in late April or early May, expect increased domestic travel, busy churches, and some changes to business hours. Pyrgos is particularly atmospheric during the Good Friday celebrations. Book accommodation and important meals early if your visit overlaps Easter weekend.
Where to Stay in Santorini in May
May is an excellent month to stay on the caldera, with better hotel prices than in summer. For a first visit, I’d choose one of the four main caldera towns rather than a beach resort.
- Imerovigli: My favorite May base for couples and honeymooners. It has Santorini’s best caldera views, excellent luxury hotels, and a peaceful atmosphere.
- Firostefani: The best mix of caldera views, quiet evenings, and practical access to Fira. Central Fira is about a 10 to 15-minute walk.
- Fira: Best for first-time visitors who want restaurants, buses, shopping, nightlife, and simple logistics.
- Oia: Best for luxury hotels, romantic stays, and sunset views. Stay overnight to enjoy the village early in the morning and after day visitors leave.
- Beach Towns: Kamari and Perissa are good for lower hotel prices and beach access, particularly in late May. The caldera towns are better for most first visits.
- Quieter Alternatives: Pyrgos is a traditional village with good restaurants and a central location. Akrotiri has quieter hotels, including some excellent luxury properties with caldera views. Both are better with a rental car.

Best Things to Do in Santorini in May
Venetsanos Winery in May, with green spring vegetation and comfortable temperatures for outdoor tastings.
- Hike from Fira to Oia: May is one of the best months for the caldera trail. Start in the morning, carry water, and wear shoes with good grip.
- Visit Santorini’s Wineries: May is excellent for outdoor tastings without the intense summer heat. Venetsanos, Santo Wines, and Estate Argyros are good choices. Reserve ahead for sunset tastings.
- Take a Caldera Boat Tour: Catamaran cruises, volcano visits, and sunset tours are popular in May. Bring a warm layer for the boat, especially after sunset.
- Explore the Caldera Villages: Oia, Fira, Firostefani, and Imerovigli are easier to explore than in July or August. Visit Oia early in the morning to avoid the busiest cruise-ship hours.
- Visit Pyrgos, Megalochori, and Emporio: May is a good month for exploring these traditional villages on foot before the summer heat makes their steep lanes and steps less appealing.
- Visit Ancient Akrotiri: The covered archaeological site works well in sunshine, wind, or light rain.
- Visit Ancient Thera: Go in the morning before the exposed site becomes warm and windy.
- Spend an Afternoon at the Beach: Kamari, Perissa, and Perivolos are good for sunbathing and a seaside lunch, even if the water is too cold for a long swim.
A May ferry arrival at Athinios port. Less chaotic than peak summer, but still busy.
What to Book Before You Arrive
- Hotels: Book early for a specific caldera-view room, private heated pool, or popular honeymoon hotel. The best rooms can sell out months ahead, even in May.
- Ferries: Book tickets in advance, especially for popular routes and high-speed ferries. Some May routes have limited departures, and the best sailing times can sell out. Check ferry schedules before booking nonrefundable hotels.
- Boat Tours: Reserve popular sunset cruises in advance and schedule the tour near the beginning of your stay in case wind forces a change.
- Restaurants: Reserve important sunset dinners and special-occasion restaurants. Restaurants are easier to book in May than in peak summer.
- Transfers: Arrange a transfer in advance if arriving by ferry, especially with luggage or when staying outside Fira. Athinios port can be crowded even in May.
A rental car is useful for wineries, beaches, Akrotiri, Pyrgos, and quieter villages but unnecessary for travelers staying in Fira and using buses, tours, and transfers.
Ferries and Island Hopping in May
May is a good month for Greek island hopping. Ferries operate between Santorini and Athens (Piraeus), Mykonos, Naxos, Paros, Ios, Crete, and Milos. Not every route runs daily, and some connections, particularly Milos and Crete, depend on the seasonal timetable.
My Greek ferry guide covers booking and schedules, with detailed pages for Athens to Santorini, Santorini to Mykonos, and Santorini to Crete.
Do not connect from a ferry directly to an important international flight. Spend the final night in Athens before flying home.
May 1 warning: May 1 is Labor Day in Greece, and ferry and public-transport strikes are common. Avoid planning an important ferry journey that day if possible. Check for announced strikes and schedule changes before traveling.
Dinner at Metaxi Mas in May. The outdoor seating is lovely, but bring a light jacket once the sun goes down.
What to Pack for Santorini in May
- Light daytime clothes: T-shirts, shorts, dresses, and other comfortable clothes for warm afternoons.
- Jacket or sweater: Essential for cool evenings, sunset dinners, and boat tours.
- Comfortable walking shoes: Santorini has cobblestones, steps, uneven lanes, and exposed hiking paths.
- Swimwear and sun protection: Bring a swimsuit, sunscreen, sunglasses, and a hat.
May Compared with April and June
- May vs. April: April is greener, quieter, and cheaper, but cooler, with more seasonal hotels and restaurants still closed. May is the better choice for most first-time visitors.
- May vs. June: June is warmer and better for swimming, beach time, and nightlife. May is better for hiking, hotel value, spring scenery, and avoiding peak crowds.
