Snow, frost and winter roads: what to expect from a mountain home in Friuli

Nights with a minimum below zero are the simplest way to compare winters: they weigh on heating bills and on icy roads in the morning. The figures are ARPA's 1991–2020 climate normals, computed on a 500-metre grid and read at each town hall. 17 towns reach at least a hundred, all of them in the mountains.

The top spot does not go to the highest town but to the Valcanale: in Tarvisio, at 760 m, the average January minimum is −6.8 °C, colder than Sappada at 1,242 m (−5.3 °C). Altitude alone does not tell the story. The whole region, summer included: Friuli's climate.

In our data, days with snow on the ground exist for only six municipalities: those with an ARPA station recording them in the 1991–2020 normals. Five are in the mountains; the sixth is Trieste.

Sauris, the highest, has snow for about a third of the year; Claut, at 618 m, for 62 days. These are thirty-year averages, and recent winters can stray a long way from them. Buyers also care how far the slopes are: from four of these villages it is a few minutes, from Claut to Piancavallo 47 min. See sea and slopes within an hour and Tarvisio, Sappada or Forni di Sopra.

In a narrow valley winter is not only cold but dark. At the winter solstice, with clear skies, the town hall gets this much direct sunshine:

• Claut: none. For 14 days, 15 to 28 December, the town hall gets no direct sunshine at all.
• Forni Avoltri 2 h 4 min, Chiusaforte 2 h 3 min, Dogna 2 h 21 min, Prato Carnico 2 h 41 min, Malborghetto Valbruna 2 h 52 min.
• Sauris, higher up: 6 h 25 min.

In Dogna the sun stays under three hours for 71 days. The figure is for the town-hall spot: within 250 metres the best point reaches 2 h 46 min in Claut and 5 h 34 min in Chiusaforte. How we calculate it, with the real horizon: winter sunshine.

Every autumn FVG Strade, the Region's company that runs regional and state roads, issues a winter order. The 2025-26 order (no. 288/2025) covered 15 November – 15 April and required every motor vehicle to have winter tyres or approved chains on board, to be fitted when needed; motorbikes and mopeds could ride only with no snow or ice on the road. The routes:

• Canal del Ferro and Carnia: the SS 13 Pontebbana from Gemona to Malborghetto, the SS 52 Carnica from Venzone to the Mauria pass, the SR 355 up the Val Degano to Sappada, the SR 512 by Lake Cavazzo, the SR 465 over the Forcella Lavardet, the former SP 22 of Val Sesis in Sappada and the SS 13/SS 54 link at Tarvisio;
• Pordenone area: the SR 251 up the Val Cellina, from Montereale to Erto e Casso, and the SR 552 over the Passo Rest;
• Julian Prealps: the SR 646 of Uccea, between Tarcento, Lusevera and Resia;
• and on the plain and the Karst too: a stretch of the R.A. 16 at Fiume Veneto and of the SR 14 and SR 58 in Trieste and Monrupino.

During the snowfalls of March 2024 FVG Strade reminded drivers that on the affected stretches, from 700 metres up, chains had to be fitted. The order is renewed every year, so check the one in force before setting off; motorways follow their own operators' rules.

Anyone buying along a pass road should know it may close in winter:

• Val Sesis (Sappada): closed for the season from 31 October 2025 to 15 May 2026.
• Passo Rest (between Socchieve and Tramonti): on 27 January 2026 it was closed by ice and snow between Caprizi and Maleon, until further notice.
• Forcella Lavardet (from Prato Carnico towards the Veneto): on 5 February 2026 it was closed by snowdrifts, on the Veneto side too.

For a home this means two things: the everyday access road should be one that is kept open, and it is worth asking who clears the last stretch, private or municipal. Travel times to A&E are measured with clear roads, 38 min from Sauris and 54 min from Claut; with snow they are longer (hospitals and travel times).
