We have been to GC a few times in October and as a rule temps have always been 27 deg and above

Thank you, Im just so confused on what Island I want to go to.

Nothing closes on the island as it's a year round destination, Oct/Nov is generally hot n sunny. Peak period on the island is during the cold Winter months in Northern Europe when the island is packed with Scandinavian visitors escaping their harsh Winter for a while !

Its great this time of the year.
Not toooo hot but hot enough!

we have stayed in Mogan in November before and found the weather to be lovely. Lots of lovely sunshine to escape the horrid frost back in the UK!
