Weather in Alonissos in July
In Alonissos, July brings high-summer weather that is hot and almost completely dry. Temperatures typically peak at around 29°C / 84°F in the afternoon and fall to about 22°C / 72°F at night. Nights stay warm, so air-conditioning helps. The sea averages about 25°C / 77°F, properly warm for swimming. Expect just 1 rainy day in a typical July. 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. Alonissos is covered in pine forest that runs down to quiet coves, and it sits within a national marine park. You get about 14½ hours of daylight a day, leaving long, light evenings. Bring loose, light clothing, a wide-brimmed hat, strong 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.

Is July a Good Time to Visit Alonissos?
July is a great time to visit Alonissos if you want long beach days, a warm sea and the island at its liveliest. Expect highs of around 29°C / 84°F and lows near 22°C / 72°F.
