Rough seas in September Turkey/Greece?
We sailed on another cruise line last year the last 2 weeks of September from Istanbul to Athens. We had wonderful weather and felt no movement at all while on ship. The seas were very calm. In fact, it was a touch on the warm side, especially in Turkey. The only time we had any motion was in tendering to one of the Greek ports. You might want to skip tendering if it is looks bouncy, but otherwise, it should be good.
May and June optimum time with July August next if you dont mind higher temps.
If you are very concerned, listen to adoctor and go in May-June. If you plan to go swimming, go in June. The water is a little chilly in May.
I found out that there is good medication for sea sickness and vertigo and will be going fully prepared. I am hoping all will be well and hopefully not to breezy! Thanks for your reply.
