Detailed cycling weather forecast for Nassfeldpass. See wind direction, temperature and rain along the entire climb and descent.

• Road access: The Nassfeld Pass road (Passo di Pramollo) is a fully paved mountain pass linking Hermagor (Austria) and Pontebba (Italy) at ~1530 m elevation; it is generally open year‑round as a road connection across the Alps, not formally closed like some higher passes such as Timmelsjoch. 
• Seasonal conditions: Although the road remains open, snow and winter weather often make the pass unsuitable for cycling outside of late spring–early autumn. Many cyclists ride it primarily June through September when snow is typically cleared and temperatures are more comfortable. 

⚠️ There isn’t an official fixed “bike‑only seasonal closure,” but winter snow, ice, and cold on the pass mean it’s generally not safe or practical for typical cycling before late spring.

• In January and February, temperatures in the Nassfeld region are around 0 °C or below, with regular snow on slopes and at higher elevations. 
• The local ski resort season runs from early December to mid‑April due to reliable snow, showing that snow remains abundant through much of spring at altitude. 
• This implies icy or snowy surfaces on the pass road throughout winter into early spring — conditions that are not ideal for road bikes.

• Late spring to early autumn (typically June–September) offers the most reliable conditions for cyclists:
  • Snow is mostly cleared off the road
  • Daytime temperatures are mild (average ~15–25 °C in summer months) 
  • Long daylight hours and dry tarmac make for safer climbing and descending.
• Even in these seasons, weather can change quickly at altitude; sudden rain or cooler temps near the summit are common.

• The pass has paved roads with moderate to steep gradients — typical of alpine passes — and is ridden by many road cyclists in summer months. 

• It’s a publicly accessible road used by cars and motorcycles; traffic volume can rise in summer on nice days. Always ride defensively.

• At or near snow season transitions (spring/late autumn), there may be remaining snowbanks, wet spots, or debris on parts of the road — be prepared for variable conditions.

• On warm summer days, the pass can be pleasant; at higher altitudes, wind and shade can make it significantly cooler than the valleys.
