The Vía de la Plata spans varied climates from Andalusia to Galicia, creating distinct seasonal patterns along the route. March, April, and October align with milder southern stages and manageable conditions farther north, reflecting late‑winter to mid‑spring and early‑autumn patterns. Outside these windows, late spring and summer bring pronounced heat across the south and Extremadura, while late autumn into mid‑winter turns progressively wetter and cooler toward Castile y León and Galicia, with frequent showers near the Atlantic.
