Traveller notes on Kos in November

Notes from nearby Selçuk (118 km away)

Kos doesn't have its own notes for November yet — these are about Selçuk, close enough to share the season.

Selçuk/Ephesus forum threads are enthusiastic about November: daytime highs around 19C with ample sunshine keep it comfortable for walking the ruins all day, even though nights turn genuinely cold enough to want a jacket. November tends to bring the most rain of the shoulder-season months here, and sunshine hours drop to around 6 a day, so some cloudy or wet stretches are normal. The trade-off forum regulars kept highlighting: the summer heat and crowds are both gone, making it one of the most pleasant windows to actually enjoy Ephesus on foot.

Other months in Kos

Forum posters describe March in Kos as genuinely unpredictable but still mild overall, sitting outside the reliably hot, dry stretch that runs roughly June through early October. Posters note showers this time of year can affect one side of the island while leaving another completely dry, reflecting how localized spring weather patterns can be here. Posters consistently recommend packing layers and a light raincoat for a March visit, ready for both sunny stretches and passing rain within the same trip. Posters generally rate March as a mild, changeable shoulder-season month for Kos, well ahead of the settled summer heat but past the harshest of the Aegean winter.

September is the month Kos regulars call the best of the year — 25 to 30°C, the sea still at 27°C, everything open, and nowhere near July and August's crowds. Evenings want a cardigan. The thing to understand about the wind is that it is directional rather than seasonal: the meltemi is a northerly running June to about mid-September, so it hits the north coast hardest — Tigaki and Mastihari especially — and the forum's fix is simply to switch sides of the island, Kardamena being the usual suggestion. Kos reads breezy year-round on the monthly averages, but an average smooths over exactly the local, directional effect regulars are describing, so take the coast advice over the number. In the heat most people count it a cooling breeze rather than a problem.
