The Via di Francesco from Roma to La Verna spans lowlands, Umbrian valleys, and the Apennine foothills, so conditions change along the way. April, May, and September generally align with milder temperatures and steadier days, with quick showers still possible. Outside these windows, summer brings stronger heat and occasional thunderstorms, while late autumn and winter trend wetter, cooler, and darker, with higher sections at times seeing frost, ice, or snow.
