Været i Mykonos i desember

Mykonos-forum threads on December weather describe an island unrecognizable from its summer self: cool, windy and sometimes rainy, rough seas capable of disrupting ferry schedules between islands, and nearly every club, beach bar and big nightlife venue shuttered for the season. What's left, per regulars, is a quiet, distinctly local version of the island - a handful of tavernas and cafes still open around Mykonos Town, streets genuinely walkable without the summer crush. Posters note island-hopping gets logistically harder this time of year, with no direct December connection to Santorini, meaning a multi-leg ferry route or a return flight via Athens instead. Regulars frame December as worthwhile only for visitors after a slow version of Mykonos rather than the party scene. The record: 16.2C days feeling like 13C, 12.2C nights, 75mm across 10.4 days, a 17.6C sea, 72 percent humidity and wind averaging over 37 km/h.

Regulars are honest this month splits into real extremes - some visitors reporting glorious 30C sunshine daily and sea warmer than June, others finding it turned chilly and a bit rainy by the time they arrived, with many businesses already closed and the island noticeably quieter either way. Our row backs that mild, still-breezy read, 23.6C over 18.6C nights, with rain minimal at 19.1mm across 2.9 days and a real 33.3 kph wind, reflecting the meltemi's lingering presence even this late in the season. Regulars are consistent the meltemi itself has mostly eased off by this point compared with its July-August peak, though a windy stretch remains genuinely possible. The sea sits at a warm, swimmable 22.2C. The record: 9.8 hours of sun and AQI 46.

Mykonos-forum threads on wind are practical rather than alarmed: the Meltemi starts picking up in June, strongest in the afternoon, and the advice is simply to plan the beach day around it rather than avoid the island - south-coast beaches like Ornos, Platis Gialos, Psarou, Paradise and Elia are named as the safer bet on a windy day, with the exposed north coast the one to skip. Crowds are called firmly summer-season but noticeably short of the July-August peak, and more than one poster calls June the smarter month for the best balance of weather, value and atmosphere on the island. The record backs the wind read directly: 28.3C days feeling like 30C, 22.1C nights, essentially none at all, a 21.5C sea and wind averaging over 30 km/h - hot, dry, and genuinely breezy.

September on Mykonos is the softening of August: still hot, almost always sunny, the huge crowds gone by mid-month and the island still lively, with businesses starting to close as the season runs out at the end of it. Our row gives 27.7C days, 22.1C nights and 0.6 precipitation days. The variable is the thing the island is named for. Mykonos sits in the path of the meltemi - it is the Island of the Winds - and although September averages less wind than July and August, our row still carries 34.8 kph, and regulars say you cannot predict the week: the sea can be a millpond one day and very rough the next, with a blow lasting days. The last week can turn cool for the beach. The record: 11.2 hours of sun and a 23.6C sea.

The meltemi peaks in July and August, and the Mykonos forum's position is that August would be unbearable without it - 35C days need the wind. The pattern regulars describe is consistent: it blows hardest through the afternoon and usually drops at night, and it comes from the north, which is why the south-facing beaches are the sheltered ones and the popular ones, with Agios Ioannis and Psarou named as the best protected. None of it thins the crowds - this is peak season, the town gets genuinely jammed, and the advice is to start early. Ferries to Delos are the thing a windy day actually cancels. The record: 29.8C days, 24.2C nights, 0.3 precipitation days, 12.6 hours of sun, a 25.5C sea and a 36 kph wind.
