Really bad luck Alan! Hope your father in law is on the mend?
November is quiet, the season ends abruptly at the end of October, but not as fully as in times gone by. There are plenty enough bars and restaurants that stay open these days, and of course Fethiye carries on as usual all year round.
Weather can be anything - glorious sunshine, torrential rain & thunderstorms and all pretty random.
I like November there, calm and quiet - but it is not the holiday resort feel of September/October.
