I am surprised to see the horror stories about sailing in November. I live in Marmaris full year since 2008 and I've never seen a hurricane
or gales here. (or we might have different definition of hurricane
and gale force winds..)
November is usually very quite and we use this season to wash up and dry our sails
at the end of charter
season under sun shine and very weak winds...
Strong winds can of course come and go and I fully support what Noelex 77 has said.
You should also bear in mind that over the last 4-5 years the weather
patterns have changed quite a bit and shifted 1 even 2 months further; hot season comes later and leaves later.. Some time ago, in May regular meltemis would have set up, sea temp. around 22-23, while November, particularly December was a risky time to sail.
Nowadays, May is quite cold, sometimes even rainy, sea water
barely touching 20 ndegrees mark. But in turn, November even December the weather is very pleasant and the sea is 20-22 degrees until Christmas
. (more on Göçek side)
In short, there is nothing to worry in sailing in November even later, provided that you take necessary measures. All what I am saying is regarding the souteastern coast of Turkey
. Aegean channel (Mikanos, Santorini, etc.) even Bodrum can be much more windy and you can find 7-8 frequently, if not 8-9 beaufort
