Good to know

Which beaches in Kos are more sheltered from the wind?

18 of the 39 face away from the meltemi, meaning less open water in front of them for a wave to build across when it blows. It is not a guarantee — the same beach changes character when the wind turns. Check the live reading before you drive out.

Which side of Kos is windier?

When the meltemi blows (from N/NE), the beaches facing north are the most open to it: none of the 12 is sheltered from it. The more sheltered side faces south: all 16 of its beaches have land between them and the wind. When the wind turns, the picture turns with it, so check live wind and waves before you go.

How is this list ordered?

By which beaches have the best conditions at that hour, so the order changes through the day: a beach that leads in the morning can drop down the list in the afternoon, once the wind picks up. When there is no live weather data, they are listed by how well known each one is — not by a score of ours.

When is the sea calmest here?

Across 39 of the beaches on this page, the open water in front of them is typically 0.78 m in June, 0.89 m in July and 0.80 m in August when the meltemi is at its strongest, and 0.75 m in September. September is the calmest month of the season. We calculate these figures ourselves from European Copernicus wave-model data at 4.2 km resolution. They describe the sea offshore, not the shelter of an individual cove — a bay protected by a headland will usually be calmer than this.

How warm is the water, month by month?

Off 39 of the beaches on this page the sea is typically 19.3 °C in May, 22.0 °C in June, 23.2 °C in July, 25.0 °C in August and 24.5 °C in September — ideal at the height of summer, mild in June. In October it is still 22.9 °C — warmer than June. August is the warmest month. Satellite measurements, 1995–2024, from a sea cell about 5 km offshore; shallow bays usually run warmer than this.

When is the weather worst in Kos?

Over the last 20 summers, the hardest week in Kos starts around 10 July: 44 days in 100 had wind of 5 Beaufort or more. In a week's holiday between 26 June and 23 July, strong wind on about 3 of the 7 days. Once it starts, it lasts about 2 days. Even then, the most sheltered side was the south coast, with beaches fit for a swim such as Daidalos, Tropical and Chelona. These are typical figures from 20 summers of European reanalysis (2006–2025), not a forecast for any single day.

How busy does it get, month by month?

August is the peak: on an average night there are about 63,093 people staying here. In October it drops to 47% of that peak — about 29,816 people, while in May it sits at 63%. From official overnight-stay figures 2024-2025: it counts whoever sleeps in the area, not day trippers or cruise passengers. It is a historical average, not a forecast for this year.
