Cordoba is hotter than hell in summer (believe me). When I was here (at the end of July) the temperature was so hot that locals didn’t go out the streets till 8 or 9 pm. They stayed at home or in places with air conditioning. So if you’re coming in July or August be ready to take five or six showers (at least) every day, and you’d better choose an air conditioned hotel.
We’ll leave the Alcazar and visit some other interesting buildings ...
