June is typically a peak month for the Greek islands, but in 2025, Santorini showed clear signs of declining momentum. According to official data published by Atlantea, all entry points to the island — air and sea — recorded a marked downturn in traffic, raising concerns among local tourism operators.
Double-digit drop in air arrivals
Passenger traffic at Santorini Airport continued to fall in June 2025, both on international and domestic routes:
International air arrivals:
✅ 105,990 passengers, down from 123,450 in June 2024
🔻 –14.1% year-on-yearInternational flights:
✅ 677 flights, compared to 827 last June
🔻 –18.1%Domestic air arrivals:
✅ 69,381 passengers, compared to 86,725 in June 2024
🔻 –20%Domestic flights:
✅ 742, down from 843 last year
🔻 –12%
Fewer scheduled flights and lower load factors across the board are weighing heavily on the island’s connectivity and overall demand.
Decline in ferry arrivals as well
Ferry arrivals also followed the downward trend, with the port of Santorini seeing fewer inbound passengers compared to last year:
Ferry arrivals:
✅ 118,674 passengers, down from 139,623 in June 2024
🔻 –15%
Despite Santorini’s status as a major Aegean hub with dense ferry connections to Piraeus, Crete, and other islands, sea traffic was not able to offset the fall in air arrivals.
Oversupply + Weak Demand = Price Pressure
The decline in demand is being compounded by an oversupply of tourist accommodation and services, leading to downward price pressure across the island.
Tourists are spending less, staying for shorter periods, and heavily relying on last-minute deals. As a result, profit margins are being squeezed, especially for smaller operators and short-term rental owners.
Down from 2024, Up from 2019
While 2025 numbers trail behind the record-breaking 2024 season, they still exceed 2019 levels, offering some long-term reassurance:
International air arrivals – June 2019: 91,335
International air arrivals – June 2025: 105,990
🔼 +16% vs. 2019
This indicates that, despite the dip from last year, Santorini’s tourism base remains robust compared to the pre-pandemic period.
Seasonal Overview: April–June Trends
The downturn isn’t limited to June. Data from April and May 2025 shows a similar pattern of decreased air traffic, shorter stays, and aggressive discounting. Atlantea’s monthly figures illustrate a progressive slowdown in arrivals — a clear sign that Santorini’s “high season” is entering more turbulent waters.

Key Takeaways
Santorini — Greece’s crown jewel of tourism — is currently navigating a mid-season correction. In summary:
Air and ferry arrivals fell sharply in June 2025, particularly among domestic and international flights.
Oversupply of listings and services is driving prices and revenues down.
Compared to 2024, the season is underperforming — but figures still beat 2019, reflecting long-term resilience.
For short-term rental owners, flexibility, differentiation, and strategic pricing are now crucial survival tools in an increasingly competitive environment.
