About weather on the Alta Via 1 (Dolomites)

Alta Via 1 runs from Lago di Braies to La Pissa across high, mostly treeline‑free limestone ground where weather flips quickly between bright spells and showers. Many walkers target July and August, when high passes are largely snow‑free, rifugi operate widely, and daylight runs long. Expect changeable summer patterns with clearer mornings and convective afternoons, cool nights even in midsummer, and brief dustings on the highest sections during passing fronts.

• Deep winter brings frequent cloud and regular snowfall, with short clear windows, sub‑freezing temperatures aloft, overcast stretches, and sharp visibility drops in passing squalls.
• Spring stays unsettled: high ground keeps wintry traits with snow and cold nights; lower terrain is cool, wet, with brief clear lulls between showers.
• Summer is changeable: bright mornings, building cloud, frequent afternoon showers or thunderstorms, cool ridges, occasional brief sleet aloft, and generally chilly nights at elevation.
• Autumn turns cooler and changeable, with sunshine, frequent showers, and occasional heavier rain; higher sections see some snowfall, colder nights, and brisk winds.
