View 12-Month Annual Overview →Aegean Meltemi Winds vs Deep Ionian & Cretan Basins
In the Aegean Sea, strong dry northerly winds (the Meltemi) in July and August induce localized vertical water mixing and localized upwelling, keeping surface temperatures around 24–25°C despite scorching ambient air temperatures. In contrast, the sheltered southern Ionian and southern Crete reach 26.3–26.8°C.
Oceanographic Phenomenon:Meltemi Wind Mixing & Southern Solar Radiation
Thermal Lag Characteristic:Strong eastern Mediterranean thermal lag: October waters across Rhodes and Crete remain remarkably mild (22.8–23.5°C), warmer than early June (21.5°C).
Peak Bathing Average:August (26.3°C)
