The sea

Average sea temperature in July at each region's official bathing-water beaches (NOAA OISST, 1991–2020). Each region links to its beaches in the beach list.

All bathing-water beaches in Greece

The average is taken over the beaches of the official register, not over all the sea of the region. Each NOAA cell is 0.25 degrees (about 25 km) wide, so close to the shore the temperature can differ a little. Beaches with no nearby sea cell (a lake, for example) are left out of the temperature column.

Comfortable for walking and sightseeing

Places with a page of their own where the month's average temperature is 16 to 24 °C and rain stays at or under 50 mm (NASA POWER MERRA-2, 2001–2020). Temperature is adjusted for the altitude of the place where OpenStreetMap records one. Up to 6 are shown per region: cities and towns first, then villages with a known altitude.

In July most lowland places are above the comfortable band: the average temperature is over 24 °C in 1,510 of 1,600. The places below stay inside the band and are typically higher up or further north.

Peloponnese (33 of 315)

Western Macedonia (25 of 39)

Epirus (10 of 75)

Central Greece (10 of 78)

Central Macedonia (4 of 165)

Eastern Macedonia and Thrace (3 of 89)

Crete (2 of 136)

Western Greece (1 of 76)

Thessaly (1 of 93)

South Aegean (1 of 171)

Beside each place: the month's average temperature and, where OpenStreetMap records it, the altitude. These are regional model values, not a measurement in the place.

Islands with comfortable weather and a warm sea

In July no island with a page has a main town with comfortable weather and a sea of 22 °C or warmer, so there is no list.

All islands of Greece

The weather is read at the island's main town by the same rule as the list of places (NASA POWER MERRA-2) and the sea from the nearest NOAA OISST cell. These are typical conditions, not a forecast.

Where to swim

1,486 beaches where the average sea temperature in July is 22 °C or warmer (NOAA OISST) and the water was classified Excellent in the 2024 season (EEA). Beaches that were Excellent in most seasons since 2011 come first. Beside each beach: municipality, sea temperature, and seasons classified Excellent out of classified seasons. Up to 6 per region.

Central Macedonia (111 beaches)

Thessaly (103 beaches)

Peloponnese (143 beaches)

Western Greece (69 beaches)

Epirus (35 beaches)

Eastern Macedonia and Thrace (53 beaches)

Attica (154 beaches)

Ionian Islands (146 beaches)

Central Greece (118 beaches)

Crete (157 beaches)

South Aegean (275 beaches)

North Aegean (122 beaches)

All bathing-water beaches in Greece

The classification is the EU assessment based on samples from four seasons, not a reading on the day. For recent samples see the official results linked from each beach page.

Daylight

Sunrise and sunset on the 15th, north to south, in Greek local time.

Calculated from the place's position and the date, without local terrain. Day length changes by a few minutes a day, so the values hold for the middle of the month.
