The Camino de Invierno from Ponferrada to Santiago crosses two distinct climates, shifting from drier mornings in Bierzo and Valdeorras to wetter Atlantic air in Galicia. April and May align with longer days, fresh greens, and mostly mild temperatures, while changeable showers remain part of the spring pattern. Weather varies between sunny breaks and rain; vineyard or canyon paths can be slick after wet periods; service availability increases after Easter.
