The weather in October is usually very good.
But being October, you do take a chance of some rain.
I was there for 14 days last year Oct 6 - 20. We had one half day of cloud, one half day of strong wind and 12 perfect days. The year before during the same period we had two days of heavy rain and the rest perfect. Of course, we could be unlucky this year and get lots of wet days but that's October.
Also remember, the days are shorter and nights can be quite chilly.
Overall though October should be good. I'll be there again this year.
