The Camino Sanabrés transitions from dry, exposed stretches in Castile y León to greener, wetter hills in Galicia, with weather shifting accordingly. April and September align with milder temperatures and a practical balance of heat, rain, daylight, and generally open services along the route. Beyond these periods, the experience ranges from hot, sun‑exposed summer stages with longer water gaps to cooler, wetter months with shorter daylight and occasional muddy tracks.
