Traveller notes on Side in September
Notes from nearby Alanya (60 km away)
Side doesn't have its own notes for September yet — these are about Alanya, close enough to share the season.
Alanya's forum calls September close to perfect, typically 27-30°C with cloudless skies and a warm sea ideal for swimming. Regulars flag online forecasts as sometimes wrongly predicting rain that never arrives, and are consistent that this is one of the more reliably sunny stretches of the year along Turkey's Mediterranean coast.
