Via degli Dei crosses the Tuscan–Emilian Apennines between Bologna and Firenze, with weather that turns quickly, from warm, still valleys to breezy ridge sections. From the seasonal patterns, April, May, and September often feature cooler walking temperatures, mixed sunshine and showers, and sufficiently long daylight for steady days. Summer leans hot with thundery downpours after sultry afternoons, while winter brings cold, ice or snow at higher points, and frequent fog.
