Meteo Nasso in gennaio

Forum posters are blunt that January isn't great weather - cold, windy, with a real chance of rain - and describe most hotels, restaurants and shops as closed for the season, which properly runs May through October. Wind is described as a near-constant feature of Mykonos generally, with genuinely windless days considered rare even outside winter. One notable exception posters flag: the 'Alkyonides Days,' a short, well-known window of calmer, sunnier weather that traditionally falls in mid-to-late January, offering a brief break from the otherwise blustery, closed-down off-season atmosphere. Outside that specific window, posters say January suits only visitors specifically seeking a quiet, off-season look at the island rather than typical Mykonos beach-and-nightlife conditions.

Regulars are specific this counts as a genuinely good month to visit, not yet high season so there are enough people around without real crowding, late May in particular described as close to perfect - warm sun without the sweaty intensity of full summer. Our row backs that mild, genuinely dry read, 22.8C over 18.8C nights feeling 17C, with rain minimal at 5mm across 1.7 days and a real 28.8 kph wind. Regulars are consistent an occasional cloudy or rainy day remains a real possibility even during an otherwise beautiful stretch, evenings cool enough that a light layer is worth having despite warm sun during the day. The sea itself stays genuinely cold, only just warm enough for some swimmers by this point. The sea sits at 18.3C. The record: 12.5 hours of sun, humidity 78 percent and AQI 52.

Regulars describe early October as lovely and mild, warm enough for short sleeves by day and most nights too, with the sea still swimmable though it can feel chillier the moment the wind picks up. Our row backs the mild read, 23C over 19.3C, with 10.9mm of rain across 2.1 days and a real 31.8 kph wind - regulars name that wind as the thing that makes the water feel colder than the number suggests rather than a change in the water itself. The season's end is uneven across the island: south coast beach tavernas and hotels start closing in early October, while Naxos Town and St George keep the full tourist infrastructure running. The trade for coming now is space - quieter beaches, lower prices, and studios quiet enough for an undisturbed night's sleep. The sea holds 22.5C. The record: humidity 74 percent, 9.9 hours of sun and AQI 46.

Asked whether June is too windy for the beach, regulars say it is early for the meltemi - mid-July at the soonest, peaking in August - and that when it does blow this month it lasts a day or two rather than a week. They also name the answer for those days: the north wind leaves the west coast sheltered, so Agios Georgios, Agios Prokopios, Agia Anna and parts of Plaka and Kastraki stay usable. One regular counts three or four days in more than a hundred where wind actually changed the plan. Their last point is a reframe - the wind is what keeps the Cyclades cooler than the mainland. Our row: 27.1C over 21.9C, a 29.4 kph average, 1.5mm of rain, 13.4 hours of sun and a 22C sea.

The meltemi does not usually begin before the middle of July and then peaks through July and August, so this month is really two: a still first half and a blowing second. Our row averages 34.8 kph across both. Regulars are firm that the wind is a blessing rather than a problem - it arrives with fine clear weather and takes the edge off a 29.2C day that otherwise reads as 31C - and that it is strongest in the afternoon, dropping away at night, with hard spells lasting a couple of days before calming. The practical answer is to pick the beach by the forecast: Agios Prokopios, Agia Anna, parts of Plaka and Kastraki on the west shelter well, and Mikri Vigla or Alyko work when it comes from the north. Rain does not exist here now: 0.1mm, no precipitation days. The record: 23.7C nights, 13.1 hours of sun and a 24.7C sea.
