What the Meltemi Does to Your Holiday

The wind that splits the island in two

I have stood on the jetty at Kissamos twice now watching a boat to Balos get cancelled thirty minutes before boarding, and both times the sky was blue. That is the part nobody believes until it happens to them: the meltemi does not announce itself with clouds. It is a strong, dry, sustained wind out of the north, and in /guides/crete-in-july-and-the-meltemi/ and /guides/crete-in-august/ it can blow for days at a stretch. Crete is about 260 km long, and that length matters here, because a wind that shuts down a jetty in the north-west can leave a beach 80 km south, on the far side of the mountains, completely flat.

If you have a boat trip booked for high season, the honest question is not “will it be windy” but “which coast is my boat leaving from.” That single fact tells you more than any forecast app.

Why Balos, Gramvousa and Chrissi are the first to go

The excursions that get cancelled most often all share a route across open, north-facing water: the /destinations/balos-gramvousa/ boats out of Kissamos, which cross an exposed stretch to reach the lagoon and the Venetian fort on /guides/imeri-gramvousa-fortress/, and the crossing to /destinations/ierapetra-chrissi/ in the far south-east.

Chrissi sits on the Libyan Sea, which usually argues in its favour, but the strait it sits in funnels the same north wind down between the mountains and the coast, so operators there watch the forecast just as closely as the ones at Kissamos. I read about this route in /guides/balos-lagoon-boat-or-road/ and /guides/chrissi-island-day-trip/ before I ever sailed it, and both pages say the same thing I now say to friends: check the boat, not just the beach.

None of this means these places are not worth seeing. It means July and August are the two months where “booked” and “will actually happen” are not quite the same word.

The Libyan Sea keeps its calm

Here is the part that makes the meltemi manageable rather than ruinous: the south coast is protected by the White Mountains and the central spine of the island, so while the north strait is churning, the Libyan Sea is often glassy. Boats to /guides/loutro-the-village-with-no-road/ and along /blog/the-south-coast-boat-network/ keep a far steadier schedule through midsummer than anything leaving from Kissamos.

The gulf of Mirabello behaves similarly: it is not the open sea, so trips to /destinations/elounda-spinalonga/ sailing between Plaka and the island — see /guides/spinalonga-which-boat-to-take/ for the three departure points — run far more reliably than the exposed western crossings, even in a proper blow.

So the useful mental map is not “Crete cancels boats in summer.” It is: north and exposed, book with slack; south or sheltered, book with more confidence.

What I actually do when a boat day falls in July or August

I never schedule a Balos, Gramvousa or Chrissi boat for my first or last full day. If the sailing is cancelled and I have no other day left, there is no fixing it — the wind does not care about my flight home. I leave at least one spare day inside the trip, ideally two, so a cancelled morning becomes a swap rather than a loss.

I also check the actual conditions, not the general season, the night before. A forecast around force 4 is usually fine for the sheltered routes and marginal for the exposed ones; force 6 or above and I expect the Kissamos boats to be off. This is exactly the kind of forecasting a private guide handles for you rather than leaving you to read wind-speed charts on holiday, which is why for a Knossos day that does not depend on the sea at all I default to something like the Souda Bay private day trip to Knossos Palace — a driver who already knows the day is a write-off for boats will simply route you inland instead.

Land-based backups worth having in your pocket

Because I now build a “what if the boat is off” plan into every high-season itinerary, I keep a short list of days that never touch open water. The /guides/knossos-palace-visitors-guide/ and the /guides/arkadi-monastery-guide/ are both full-day options regardless of wind, and a guided guided Samaria gorge day with a professional guide runs on a mountain trail, not a jetty, so it is immune to the same forecast that grounds the Balos boats.

On a genuinely wild day I have also swapped a sea plan for a guided scooter run through the Therisso gorge villages, which stays inland the whole way, or spent the afternoon on WWII history with a two-day Battle of Crete tour that was already on my list before the wind ever came up. None of these are consolation prizes — I would recommend them on a calm day too — but they are also the days I reach for first when /guides/best-time-to-visit-crete/ meets a meltemi week head-on.

What I won’t promise you

I will not tell you that a boat trip booked for July or August will definitely go ahead as scheduled, because I don’t know that, and neither does the operator until the morning of. I also will not promise a refund on your behalf — that is between you and the boat company, and policies vary. What I will say is that the pattern is well understood and genuinely predictable in shape, even if the exact day is not: the exposed north-west and the Chrissi strait are the routes that go first, the sheltered south and the gulf of Mirabello are the ones that mostly hold, and a spare day built into the trip turns a cancelled sailing into a swap instead of a loss.

Meltemi FAQ: boat trips, refunds and backup plans

What exactly is the meltemi?

A strong, dry north wind that blows across the Aegean, concentrated in July and August, sometimes running for several days in a row at force 6 or 7.

Does the meltemi affect the whole island the same way?

No. It hits the north-facing coast hardest — Kissamos, Balos, Gramvousa and the strait off Chrissi — while the south coast, on the Libyan Sea, is sheltered by the mountains and often stays calm.

Can I get a refund if my boat trip is cancelled for wind?

Most operators offer a refund or a rescheduled date when they cancel for safety reasons, but the policy is set by the boat company, not by me, and I never promise one in advance.

Should I book my Balos or Chrissi boat for the first day of my trip?

No. Book it with several days of slack before your flight home, so a cancelled sailing has room to move to another day.

Is Elounda or Spinalonga also at risk from the meltemi?

Less so. Those boats sail inside the sheltered gulf of Mirabello rather than the open strait, so cancellations there are rarer than at Balos or Gramvousa.

What should I do on a windy day instead?

Switch to something inland — Knossos, a gorge with tree cover, a winery, a museum, or a guided day that never depended on a calm sea in the first place.

Is the meltemi dangerous to swim in?

On an exposed north-facing beach it can whip up a real chop and a rip current; on a sheltered bay or the south coast the sea usually stays swimmable.

When is the meltemi least likely to interfere with my plans?

Outside July and August. June and September carry some wind days but far fewer than midsummer, and by October it has mostly stopped.
