The question was stated as what is the weather like in October not what will it be in October...no need for such a flipent answer, doesn't help anyone tbh.
There are internet sites that can give statistics on the weather but asking other cruisers helps to gauge what clothing etc to take on holiday. If you dont like the question dont answer aldrich.
Give us a clue where .
I have been kind and researched where the Island Escape is in October. The western Med. At this time of year it is cooler 60 - 70 F, sometimes warmer than that. It is usually sunny but the daylight is shorter so go out early to get the best of the day. evenings can be chilly on deck so take a lighweight jacket which can also be used against any rain.
