The Cammino di San Benedetto crosses varied elevations where weather turns quickly, alternating brighter intervals with overcast skies, showers, and the occasional thunderstorm. April, May, and September bring milder temperatures, longer daylight, spring flowers or late‑summer clarity, and firmer trail conditions across the higher Apennine sections around Norcia. Across the year, showers can arrive in any season, valleys trend warmer than ridges, and a cool breeze often persists at altitude.
