Running north–south from Stade to Augsburg through open farmland, gentle uplands, and river corridors, this pilgrimage sees quick shifts between bright spells and passing showers. Windows around April and September tend to offer longer daylight, moderate temperatures, and fewer heat‑and‑thunderstorm disruptions than early summer while avoiding the short, wintry days of late autumn and winter. Outside these periods, the pattern remains workable but more variable, with spring’s brisk mornings, summer heat spikes and thunderstorms, and late‑season cool, grey runs that slow drying and reduce consistency.
