The region has some of the most extreme temperatures in Spain as a result of its continental position, far from the blaming effects of the the Atlantic and Mediterranean. The valley of Jiloca in Teruel is probably the most consistently cold corner of the Iberian Peninsula, high mountains aside, with record temperatures of -28/-30ºC in Calamocha. (see temperature records in Spain). The valley lies in a triangle formed by Teruel, Calamocha and Molino de Aragon (over the border in Guadalajara) similarly considered as the coldest area of Spain, with temperatures regularly dropping to -20ºC.
