Weather in Nisyros in September
In Nisyros, September brings late-summer weather that is hot and almost completely dry. Temperatures typically peak at around 28°C / 82°F in the afternoon and fall to about 23°C / 73°F at night. Nights stay warm, so air-conditioning helps. You're very unlikely to see any rain. In the water, expect around 25°C / 77°F, warm enough for long swims. Nisyros is a round volcanic island, and its crater floor can feel much hotter than the coast on still days. The first autumn storms can arrive, usually as short, sharp showers between long spells of sunshine. You get about 12½ hours of daylight a day. Pack light, breathable clothes, a sun hat, high-factor sunscreen and sunglasses. When the wind picks up, a light windproof layer is handy for evenings by the water. Plan sightseeing for the early morning or evening, and keep the midday hours for the beach or a shaded taverna.
Swimming in Nisyros in September
September is a great month for swimming in Nisyros, with water temperatures around 25°C / 76°F. After the warmest water of August, the sea cools only slowly. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Many coves are rocky or pebbly, so water shoes are useful. Beach bars and sunbeds are open, with more space than in July and August.
