The cavern sits on the open north-east face of Cape Drapano, just outside Souda Bay and looking out across the Sea of Crete, so it takes the full reach of the summer Meltemi (N-NW) and any wind-wave fetch from the N through E. The peninsula and Souda Bay behind it (S-SW-W) shelter those landward sectors completely. There is no real tide or ocean swell, but on Meltemi days surge can build at the 10 m entrance even though the long tunnel keeps the interior hall calm.
