Pécs is situated in a valley, so the climate can be either VERY hot in the summer and fairly cold in the winter. The winters aren't that long though, but during summer, the temperature can rise up to above 35C.
Of course you can buy anything in Pécs, you're not exactly stranded... :)
Don't worry if you forget your underwear - you can always get some in this shop on the main square!!!!
Hey it may not be sexy but you could always use it as a tent and go camping for your next trip!
