Traveller notes on Marmaris
What people who have been say about the place — the year-round notes first, then month by month.
Marmaris forum posters describe March as a genuine coin-flip month: warm and sunny stretches alternate with days of proper rain, and one traveler mentioned being confined to their hotel for a stretch of torrential downpours before the sun came back out. Evenings turn chilly regardless of how the day went, so a layer is worth carrying even on a nice afternoon. Most restaurants and bars away from the immediate beachfront stay open through the off-season, so there's no shortage of places to wait out a rainy spell - just don't expect beach weather to hold for a whole week straight.
Forum posters describe early September as still genuinely hot - mid-to-high 30sC - cooling gradually to the low 30sC by month's end, with sea and pool water staying nicely warm after a full summer of sun. By around the third week, posters note nights start cooling enough that air conditioning becomes unnecessary, and a cardigan may be useful for the very end of the month. Weather is described as largely excellent but genuinely 'hit or miss' at times, with occasional torrential storms (thunder and lightning) reported, though these clear within hours rather than settling in. The overall consensus: September ranks among the best months to visit, with comfortable day and night temperatures plus better bargains once school-age tourists have gone home.
