From experience in previous years almost everything will be open until end-Oct. Weather in Oct can be variable but on most days if you're lucky then expect temps in mid 20's C (shorts & T-shirts weather) dropping into the mid-teens at night (jacket or light sweater). Rain for a few hours on at least 1 day a week. Could be worse, could be better.

We were in PP/Alcudia last year from 16th October for one week. For the first two days we had showers, but warm rain!! From then on we had brilliant weather, sunbathing by the pool everyday. Couldn't fault it, and the fact that there weren't so many crowds about.
