Traveller notes on Datça in December

Other months in Datça

Turkish Aegean coast forum threads describe March as the hardest month to predict - a given week could bring a full stretch of cloudy days with showers, or non-stop sunshine, or something in between, with wind a notable factor for anyone timing an outdoor activity. Posters compared it to January but with longer days and stronger sun, meaning more days lean toward pleasant than not even though real rain is still possible. One detail specific to Datça and this stretch of coast: the sea stays genuinely chilly through spring, not warming up properly until closer to summer, so March visitors shouldn't expect swimming weather even on a sunny day.

Forum posters name September as one of the best months to visit this stretch of Turkey's Aegean coast - warm but not as intense as July-August, with the sea at its warmest point of the year and evenings turning noticeably cooler than peak summer. Posters describe the region's rains as reliably stopping around May and not returning until the very end of September or into October, making September itself typically dry throughout. Posters consistently praise Datca's beaches, bays and scenery, with autumn specifically singled out as an especially attractive time for the peninsula's quieter coves once the summer crowds thin.
