Weather in Koufonisia in June
June is early summer in Koufonisia: warm and almost completely dry. Average highs reach 26°C / 78°F, with lows of around 21°C / 69°F. In the water, expect around 22°C / 72°F, comfortable for swimming. Rain is almost unheard of. Koufonisia are small, low islands southeast of Naxos, with little shade but some of the clearest water in the Cyclades. The meltemi, the northerly wind of the Aegean, blows on many days and takes the edge off the heat, though it can also whip up dust and rough seas. You get about 14½ hours of daylight a day, leaving long, light evenings. Summer clothes are fine by day, with a light layer for the evenings and plenty of sunscreen. When the wind picks up, a light windproof layer is handy for evenings by the water. Evenings are the best time to be out, when the heat fades and the light softens. It's pleasant to be outside from morning to evening, with sun protection at midday.
