May through September gives the most settled weather, with July and August the busiest and warmest months. The meltemi is generally gentler here than in the Cyclades, though it can still raise a chop around the more exposed northern islets. June and September offer calmer seas, quieter anchorages and water still warm enough for long swims.
Alonissos has no airport of its own. The nearest is on Skiathos, around 2.5 kilometres from Skiathos town, followed by a ferry crossing of roughly two hours. Seasonal direct ferries also run from the mainland ports of Volos and Agios Konstantinos, taking three to five hours depending on the vessel and route.
Patitiri, the main port, is the most convenient for provisioning and an evening ashore, with tavernas along the harbourfront. Votsi, just around the headland, offers a quieter fishing-village alternative. Kokkinokastro and Agios Dimitrios further south suit a calm daytime stop for swimming rather than an overnight, given their more limited facilities.
Two to three nights allow time to explore Patitiri and the old village above it, swim at Kokkinokastro, and still venture into the marine park’s outer waters toward Peristera or Kyra Panagia. As the quietest of the main Sporades, Alonissos rewards a slower pace than a single overnight stop allows, and it pairs naturally with Skiathos and Skopelos on a wider island-hopping itinerary through the group.
The waters immediately around Alonissos and Peristera fall under the park’s more relaxed Zone B, where normal cruising applies alongside a few local speed limits. The outer Zone A, covering Kyra Panagia, Gioura, Piperi and Psathoura, is far more strictly protected and closed to casual mooring, so a captain wanting to explore that far north should contact the park’s Management Body in advance rather than assume access.
