June is one of the best months to visit Santorini, and genuinely not enough people realize it. You get proper summer weather, ridiculously long days, and a fraction of the July–August crowds. If your travel dates are flexible, June deserves serious consideration.
What's open: Most hotels and villas open for the season in June; wineries including Santo Wines, Domaine Sigalas, and Venetsanos offer tastings; volcano and hot springs tours operating; catamaran cruises available
Santorini Weather in June
June weather in Santorini is reliably excellent. Here’s what to expect:
- Average high: 27–30°C (81–86°F)
- Average low: 19–22°C (66–72°F)
- Sea temperature: 22–24°C — warm enough to swim comfortably
- Sunshine hours: 12–14 hours per day
- Rain: virtually zero. June averages less than 5mm rainfall
- Wind: Meltemi winds begin in late June — refreshing breeze, not a problem
June gives you full Santorini summer without the brutal 35°C+ heat of August. The light is extraordinary — long golden hours morning and evening, perfect for photography and caldera walks. August can feel like standing on a griddle by noon. June doesn’t do that to you.
How Busy Is Santorini in June?
June is shoulder season trending toward peak. Early June (1st–15th) is noticeably quieter than July and August — restaurants are actually bookable without weeks of advance notice, caldera sunsets in Oia are crowded but survivable, and accommodation prices run 15–30% lower than peak.

Late June (16th–30th) starts to feel more like peak season as European school holidays kick in. Still manageable, especially if you base yourself in smaller villages like Imerovigli or Pyrgos rather than Oia or Fira, where the cruise ship day-trippers tend to cluster.
What to Do in Santorini in June
Catamaran Sunset Cruise
June is arguably the best month for a catamaran cruise. The sea is calm, the water is warm enough to swim in the hot springs, and sunset falls around 8:45pm — meaning extraordinary light stretches on for hours. Small-group catamarans sell out fast. Book at least 1–2 weeks ahead, more if you’re visiting late June.
Volcano & Hot Springs Tour
The Nea Kameni volcano hike works well in June — warm but not punishing, unlike August when the dark volcanic rock radiates heat like an oven. The hot springs at Palea Kameni sit at a pleasant 28–30°C. Go on the morning departures (8–9am) and you’ll be back before midday heat sets in.
Wine Tasting
Pre-harvest June means wineries are focused on the vines rather than tour groups. You get a more personal experience than during peak season. Estate wineries like Santo Wines, Domaine Sigalas, and Venetsanos all do tastings with caldera views — Venetsanos in particular has a terrace that makes the wine taste better just by existing.
Beach Days
The black and red volcanic beaches — Perissa, Kamari, Red Beach — are warm and swimmable but not yet packed. Early June is the sweet spot. Umbrellas are available without a fight, queues are short, and the sea temperature is perfect. Red Beach gets crowded later in summer; in early June you can actually spread out.
Oia Walking Trail
The 10km caldera walk from Oia to Fira is best done in June — warm but not dangerously hot. Start at 7am from Oia, walk south through Firostefani and Imerovigli, and you’ll arrive in Fira around 10am before the heat peaks and the cruise ship crowds arrive. Bring water. More water than you think you need.
June Events in Santorini
- Santorini Jazz Festival — usually held mid-June at the open-air cinema in Oia. Check local listings for 2026 dates
- Feast of St John (24 June) — bonfires on beaches across the island, a traditional midsummer celebration worth staying up for
- Caldera Moonrise — June full moon rising over the caldera is one of the most spectacular natural events on the island
Where to Stay in June
Most hotels and villas open for the season in June, so availability is solid in early June especially. Recommendations:
- Budget: Perissa or Kamari — beach hotels with great value, easy bus access to Fira
- Mid-range: Fira or Firostefani — real caldera views without Oia prices
- Splurge: Oia cave hotels with private plunge pools — book 3–4 months ahead even for June, they go fast
What to Pack for June
- Light summer clothing — linen, cotton
- Good walking shoes for the caldera path and village cobblestones
- High SPF sunscreen — the volcanic white walls amplify UV reflection more than most people expect
- Light jacket for evenings (19–22°C after dark)
- Swimwear — you’ll be in the water every day
Is June the Best Time to Visit Santorini?
For most travellers, yes. June gives you summer heat without the intensity of August, a swimmable sea, long daylight hours, lower prices than peak, and a version of Santorini that still feels somewhat manageable — not the wall-to-wall crowds of high season.
The only reason to choose July or August over June is if you specifically want the buzzing nightlife and festival atmosphere of peak summer. For sunsets, beaches, sailing, and actually enjoying the island — June wins. It’s not a close contest.
