Can you swim or snorkel in Rhodes in July?
At 27.7°C our temperature-only guide describes the water as warm water. Comfort depends on your cold tolerance, immersion time and wind. A historical average cannot determine whether conditions are safe on any given day.
Do you need a wetsuit?
Most people are comfortable in swimwear or a light rash guard.
Which beach should you choose?
Look for a beach sheltered from the actual forecast waves and wind on your visit. Exposure, currents and entry conditions vary even where water temperatures are similar. Follow local warnings.
Rhodes is in the Dodecanese. Anthony Quinn Bay and other rocky coves can feel different from open coast even when the island water temperature is similar. Check the beach forecast for wind and waves; temperature is not a snorkel-safety score.
