Greece Sea Temperature in September

Historical 30-year sea surface temperatures across 62 coastlines in Greece for September. Derived from NOAA 0.25° blended satellite and in-situ marine observations.

Notice: 30-year historical climatological monthly mean (1991–2020), not a live single-day sensor forecast.

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)
