Hi Pjn, the majority of bars close down end of October, 1st week in November, although there are still lots of bars/restaurants in old town Albufeira and on the strip (New town) to choose from which stay open all winter. (Floyds bar i am sure is open all winter months) Have a look at
http://www.wunderground.com for weather there is a link to go into the history of weather conditions for previous years. The weather can be good in November but not guaranteed,can be coolish at nightime,so take a sweater or light coat. Twilight is around 17.30hrs Cheers jayjan
