The Camino Ignaciano crosses from the damp Atlantic climate of the Basque Country into drier, more exposed country through La Rioja and Aragon before finishing in Catalonia. From these patterns, April, September, and October align with cooler, steadier walking weather and decent daylight while avoiding the peak heat and the darker, wetter stretch of mid‑winter. Expect a blend of showers and sunny spells up north, increasingly open, sunlit terrain in the interior, and intermittent heavier rain events as Catalonia approaches.
