Best Time to Visit Greece: Island Seasons, Ferries, and Points Value
By The Beyond Points Team · Published 2026-07-25 · Last verified 2026-07-26
The short answer: The best time to visit Greece is the shoulder seasons — May–June and September to early October: warm seas, open islands, and fewer crowds than the July–August peak. The crucial difference from most destinations is that Greece's islands are strongly seasonal: high-speed ferries run mainly ~April/May to October, and much of Santorini and Mykonos closes November–April. So timing decides access, not just comfort. Summer is hot and crowded, with meltemi winds that can disrupt ferries; winter is Athens-and-mainland only, but cheap and quiet. For points travelers, the season shapes island hotel prices (spiky in summer) far more than the Athens flight. Confirm ferry schedules and hotel openings before you book.
Greece month by month
Athens and the mainland stay open year-round; the islands run on a season. This is a typical pattern — confirm current ferry schedules and hotel openings, which vary by island and year.
| Months | Weather | Islands & ferries | Crowds & price | Points angle |
|---|---|---|---|---|
| April | Mild, spring; cool sea | Islands opening; ferries ramping up | Low; Orthodox Easter spikes | Good award space; confirm island openings |
| May–June | Warm, dry; sea warming | Open; ferries frequent | Shoulder — great value | Sweet spot: open islands, lower rates |
| July–August | Hot; meltemi winds | Peak service; possible wind delays | Peak — priciest, crowded | Island hotels spike; book far ahead |
| September–early Oct | Warm; warm sea | Still open; ferries frequent | Easing — best overall value | Best mix of open islands + value |
| Late Oct–March | Cool, wetter | Islands largely closed; ferries reduced | Low (Athens only) | Cheap Athens/mainland; skip the islands |
The rule: for the islands, travel May–June or September–early October; for Athens and the mainland, any season works, with winter the cheapest.
The best months to aim for
- Late May–June — islands open, seas warming, and value strong before the peak.
- September–early October — arguably the best: the sea is at its warmest, crowds thin, and islands remain fully open.
- July–August — peak everything: heat, crowds, and prices, plus meltemi winds that can cancel high-speed ferries. Book hotels and transfers well ahead.
- November–April — Athens and the mainland only; most island hotels, restaurants, and ferries wind down.
Islands, mainland, and the winds
- Cyclades (Santorini, Mykonos, Naxos, Paros) — the postcard islands; fully seasonal, busiest in summer, largely closed in winter.
- Crete & the Dodecanese (Rhodes) — larger, with a longer season and some year-round life, though quieter in winter.
- Ionian (Corfu) — greener and a touch wetter; strong spring and early summer.
- Athens & the mainland (Delphi, Meteora) — open all year; pleasant in spring and fall, mild and cheap in winter.
- The meltemi — strong summer north winds (mainly July–August) that can disrupt Aegean ferries; build buffer time into island itineraries.
How the season changes booking on points
- Flights — Athens award space is tightest around summer and Orthodox Easter; the seasonal US nonstops themselves run mainly in summer. Book premium space early via a low-surcharge Star program or Flying Blue (see Greece on points). From the East Coast, New York to Athens on points covers the seasonal nonstops and the Emirates fifth-freedom option.
- Hotels — Athens chains are fairly steady, but island rates and dynamic points prices spike hard in summer, and most island chain inventory is limited to begin with. Fixed-chart Hyatt in Athens holds value; islands are mostly cash (see points vs. cash for hotels).
Cash vs. points by season
- Flights: points for business on the Athens long-haul, especially at peak when cash is high; economy is often cheaper on cash.
- Athens hotels: compare — chain awards (Hyatt best) can win.
- Island hotels: usually cash, and most valuable to book early for summer, when both cash and points prices peak.

Common mistakes
- Booking islands in the off-season. Santorini in winter is largely closed; save the islands for May–October.
- Assuming ferries run year-round. High-speed service is seasonal and weather-dependent — confirm schedules.
- Ignoring the meltemi. Summer winds can cancel ferries; leave buffer days around island hops.
- Overpaying for island hotels at peak. Summer rates spike; shoulder months deliver the same islands for less.
- Transferring points before confirming availability. Confirm the seat, ferry, and hotel first — transfers can't be undone.
How Beyond Points helps
Greece's timing is really an access-and-value question: the islands are only fully open and reachable for part of the year, summer spikes prices and risks ferry disruptions, and the hotel decision splits between Athens chains and island cash. Getting it right means lining up the flight, the season, and the island logistics together.
Beyond Points weighs the programs and cash fares that reach Athens for your dates, and Athens hotel awards against island cash options — then recommends when to go for open islands, good weather, and the best value.
Conclusion
Greece is at its best in the shoulder seasons — May–June and September to early October — when the islands are open, the sea is warm, and prices ease. Summer is peak and windy; winter is Athens-and-mainland only. Book premium flights early, use points on the flight and Athens hotels, plan island lodging on cash, and — most important — confirm ferries run and your island hotel is open before you commit. Time it well and the Aegean delivers one of the Mediterranean's best trips.
Frequently asked questions
What is the best time to visit Greece?
For the islands, late spring (May–June) and early fall (September–early October) are ideal — warm seas, open hotels, and fewer crowds than the July–August peak. Athens and the mainland are pleasant year-round and cheapest in winter, when most island tourism shuts down.
Are the Greek islands open in winter?
Mostly not. Much of Santorini, Mykonos, and the smaller Cyclades — hotels, restaurants, and ferry service — closes roughly November through April. Larger islands like Crete and Rhodes keep more open, but for the classic island experience, travel between about May and October.
When do ferries run in Greece?
High-speed catamarans to the islands run mainly from about April/May through October, peaking in summer. Winter service is slower, reduced, or absent on many routes, and summer meltemi winds can cause cancellations. Always confirm current schedules and leave buffer time around island hops.
Is summer a bad time to visit Greece?
It's the peak — hot, crowded, and priciest, with strong meltemi winds in July and August that can disrupt ferries. The islands are fully open and lively, but you'll pay top rates and fight crowds. Shoulder months (June, September) offer nearly the same experience with better value and calmer seas.
Does the season affect points value in Greece?
Mostly on island hotels, where summer sends both cash and dynamic points prices soaring and chain inventory is thin. Athens chain hotels (Hyatt best) are steadier, and the Athens flight is a points win at peak when cash fares are high. Book summer island stays and premium flights early.
When is the cheapest time to visit Greece?
Winter is cheapest overall, but only for Athens and the mainland since the islands largely close. For an island trip on a budget, the shoulder months — late May–June and September–early October — offer the best balance of open islands, good weather, and lower prices.
