Sun and shade come from the sun's position and the skyline around each beach, measured every 4° of compass direction from a 30 m elevation model out to 6 km. The climb back up is the height difference between the beach and the nearest mapped car park or bus stop (about 0.17 m per step). Water depth comes from the EMODnet seabed model; surface, beach clubs, toilets and showers from OpenStreetMap; sea temperature is the 1991–2020 average from NOAA OISST and waves the 2015–2024 average from ERA5. Prices are not shown: they change every season and differ between clubs. Map data checked 7 Nov 2026; next check 1 Dec 2026 (monthly). Sea averages are refreshed every January.
