Ocotber is normally pretty good. Daytimes we expect temperatures in the high 60's/low70's F (18 - 22C) night-times are starting to feel a little cool. It does rain in October, often in the form of quite violent storms but last year it was very quiet weatherwise.
it's not exactly beach weather for some but very pleasant indeed.
Most of the tourists are long gone, but golfers are usually here in numbers. Playing golf in weather akin to an English summer is preferable to battling the elements back home!
Late October marks the end of the summer season and that's when restaurants and bars whose main trade is tourists start to close up for the winter.
It's a good time to visit while avoiding the crowds.
