This route climbs from the dry Almería coast into Granada’s uplands and continues across long, exposed stretches toward Extremadura, where shade is scarce and services can be widely spaced. Conditions often align in March and September, with workable temperatures and daylight for the climbs and open plains. Late winter to early spring and early to mid autumn generally avoid deep winter cold snaps and the intense inland summer heat, while allowing workable daylight; expect spring showers or isolated wintry spells near higher ground, and in autumn, first rains that can arrive in short, heavy bursts.
