I run DanEri’s Rhodes base, και the question I hear at the marina before almost every cruise is the same one: “will the water be warm enough?” Rhodes has a happy answer. Sitting down in the Dodecanese, off the warm Turkish coast, its sea runs a touch warmer for longer than most of the Aegean — the swimming season here stretches well into November. Here is exactly what to expect, month by month, και which coast to pick on a windy ημέρας.
The sea around Rhodes is warmest in August at about 26°C (79°F), nudging 27°C in the warmest spells, με September a close second. It’s comfortable for swimming από late May right through November — longer than most ελληνικό islands — sitting above about 21°C. The coldest water is in February at around 16°C (61°F). Για ζεστά νερά με λιγότερο κόσμο, ο Σεπτέμβριος είναι ιδανικός.
Rhodes sea temperature, month by month
Πατήστε όποιον μήνα θέλετε για να δείτε πόσο ζεστό είναι το νερό και αν είναι μήνας για κολύμπι.
Written by Captain George Bantis, who runs DanEri’s Rhodes base και sails the east coast most mornings in season, using long-term sea-surface-temperature averages for the Dodecanese cross-checked against what we record at the swim stops. Figures are typical monthly averages και vary a little year to year και between the sheltered east coast και the windier west.
Rhodes Sea Temperature Month by Month
These are the typical average sea-surface temperatures around Rhodes. The warmest water arrives in August και September because the sea spends all summer absorbing heat και releases it slowly — και because Rhodes sits so far south-east, it holds that warmth later into autumn than the rest of Greece.

Τι θεωρείται «αρκετά ζεστό»;
Comfort is personal, but there’s a rough scale most swimmers agree on. Below about 18°C the sea is bracing και you won’t linger without a wetsuit. από 19 to 21°C it’s refreshing — fine for a swim, but a rash vest extends your comfort if you’re snorkelling. από 22°C it’s genuinely comfortable, και από 25°C it’s warm enough to stay in as long as you like, which is what makes the swim-through cave at Traganou και the long stop at Anthony Quinn so good in late summer.
Γιατί η θάλασσα είναι πιο ζεστή στα τέλη του καλοκαιριού, όχι στο μέσο
Water holds heat far longer than air does. Through spring the sun warms the land quickly while the sea lags behind, which is why a hot 29°C ημέρας in May can still sit over a cool 20°C sea. By August the water has had months to absorb that heat, so it peaks late — και Rhodes, tucked into the warm south-east corner of the Aegean, cools more slowly than the rest of Greece, staying pleasant deep into autumn. It’s the best argument for an early-autumn trip: the air has eased off, but the sea is still holding summer.
The sea (teal) trails the air (gold) by a month or two — coolest in late winter, warmest in late summer, και still swimmable around 21°C in November when most of Greece has cooled.
Late summer holds the warmest water of the year — ideal for the long anchored swims και the cave the east-coast ημέρας is built around.
East Coast vs West Coast
Rhodes has two very different seas, και on a windy ημέρας the choice matters. The east coast — where our cruises run, past Κόλπος Άντονι Κουίν, Λαδικό και το Traganou cave — faces away από the prevailing northwesterly meltemi, so it stays warmer, calmer και clearer through the summer. The west coast around Ialysos catches that wind head-on; it’s a degree or two cooler, choppier, και beloved by windsurfers for exactly that reason. If the forecast looks breezy, head east.
Τι σημαίνει αυτό για την κρουαζιέρα σας
Η θερμοκρασία της θάλασσας είναι πραγματικά για το πόσο καιρό θα θέλετε να είστε σε Το the water, και that shapes which ημέρας to Κράτηση. από June to September the water is warm enough that a full ημέρας along the east coast — several anchored swims, snorkelling και the swim-through cave at Traganou — is effortless; this is peak swimming season. In May, October και November the midday sea is at its warmest, so a daytime cruise gives you far more comfortable swim time than an evening sail. Whenever you come, we read the wind each πρωινή και pick the calmest, clearest bays of the ημέρας.
