Weather in Kalymnos in July
July in Kalymnos means high-summer conditions: hot and almost completely dry. Daytime highs average around 33°C / 92°F, and nights drop to about 23°C / 74°F. Even after dark it stays warm, so a room with air-conditioning makes a difference. Rain is almost unheard of. In the water, expect around 23°C / 73°F, comfortable for swimming. Kalymnos is a rugged, rocky island, and its limestone cliffs are famous among climbers from all over the world. 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. Days bring around 14½ hours of daylight, 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. Get out early and late, and save the hottest hours of the afternoon for the water.
Swimming in Kalymnos in July
Swimming is excellent in Kalymnos in July, with the sea averaging around 23°C / 74°F. Swimming season is well underway, though the water keeps warming until August. Masouri is a local favorite. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Beaches are at their busiest now, so go early or late in the day. You won't need a wetsuit.

Festivals & Holidays in Kalymnos in July

Summer evenings are the time for festivals, open-air cinemas and late dinners outdoors.
