well, thats right, in the winter its really quiet. There is not much entertainment like clubs, pubs etc open. Only in the non touristic cities like Nicosia, Limassol and Larnaca there are few places to go. Often with greek music only. You can have fun there too, once you get used to the music and the way of life of the people.... But the summer definitely makes up for that calm time in the winter.
I've lived in CY for four years, 1996-2000, now "back home" in Germany.
My suggestion is: use the winter to relax and get power to be able to stand the summer season!
cheers, city
