The Vía Podiensis spans cool high plateaus, dry causses, rolling Gascon farmland, and wetter Pyrenean foothills, producing distinct seasonal patterns. Late spring and early autumn stand out, especially April, May, and September, when services are broadly available and temperatures trend mild to warm. Early summer can turn hot with afternoon thunderstorm risk on exposed sections, while winter brings short daylight, frequent rain, and snow or ice on uplands; later autumn trends changeable with crisp mornings, valley fog, and some lodging reductions.
