Weather in Ródos in September

Prime time. If you get to pick your dates, September is the one. Highs average 28.9 °C, lows 24.1 °C, and rain falls on 3 days — nothing in the month is working against you.

September ranks 4 of 12 in Ródos: past the worst of the year but short of May, which is the month to book if the dates are open.

Rain falls on only 3 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 28.9 °C days and 24.1 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 9 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.8 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest September day reached 35.7 °C and the coldest night fell to 18.3 °C, and the wettest single day dropped 27 mm — roughly 150% of the month's rain in one day.

This is the volatile part. September rainfall has ranged from 0 mm to 69 mm across the twenty years measured — a 69 mm spread around an average of 18 mm. The average is real but almost no individual September looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 15.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 62%.

How September sits in the year

The month is on the way down: 3 °C cooler than August, with October dropping another 4.1 °C. The first week and the last are not the same trip.

Daylight in September

12.5 hours of daylight, losing 1.1 hours across the month. That is between Ródos's extremes of 14.6 and 9.7 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 25.3 °C in September — warm enough to stay in as long as you like. This is the warmest the water gets all year.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Ródos versus nearby

If Ródos is one option among several, the nearby comparison is worth making. Antalya is the weaker option in September — 5.6 °C warmer, the same number of rain days. İzmir is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: September works, with May the better month by 7 points if the dates can move. If they cannot, nothing here should stop you booking.
