This route follows Atlantic Galicia, where weather shifts quickly between bright sun, fast-moving showers, periods of thicker cloud with rain, and cooler, darker winter spells. May, June, and September offer long daylight, warm temperatures, and steady Arousa estuary boat schedules along the Variante Espiritual for this route. During the warmer window, forest shade and coastal breezes temper heat, yet wet granite, timber boardwalks, and leaf litter can turn slick after rain.
