What is the weather like in Santorino in October ? is it nicer enough to swim in the sea and is it a safe place for a woman to visit alone?
Question about Santorini
Have a look at our <a href="http://www.worldreviewer.com/world-weather/">World Weather Guide</a> and click on Greece for the weather conditions.
I've been with a girlfriend, and as two women we had no problems. It's quite a busy place as far as visitors are concerned and we made friends with another group and went for outings with them, so you might do the same.
