Ocean surface temperatures worldwide hit record highs in June 2026, according to Copernicus climate data, with global averages approaching 21°C. The Mediterranean, including waters around Crete, is affected by this broader warming trend. For visitors, this means sea temperatures along Cretan beaches are warmer than seasonal norms, making swimming comfortable earlier in the day and later into the evening. However, warmer seas can intensify heat and humidity on shore, particularly in coastal areas. Tourists are advised to stay hydrated, limit sun exposure between 11:00 and 16:00, and apply high-SPF sunscreen. Water sports and boat excursions remain fully operational, but check conditions with local operators before heading out, as unusual warmth can occasionally affect sea currents and jellyfish presence near popular swimming spots.
