Castelluccio di Norcia Weather: Forecast and Climate

Castelluccio di Norcia Weather: Forecast for the Coming Days

To read the Castelluccio di Norcia forecast, the shape of the plain must be taken into account. The village is at 1,452 meters, while the Pian Grande is a flat valley floor about 7 km long at about 1,270 meters, enclosed by mountains. With high pressure, still air and snow on the ground, the basin fills with very cold air.

In winter it is worth checking the forecast the same morning and expecting the wind on the pass to be almost always stronger than in the valley. For those arriving from the Marche it is also useful to check the weather at Forca di Presta and at Forca Canapine, two mountain passes at 1,536 m and 1,541 m respectively.

Piano Grande and Castelluccio Weather: Snow and Conditions

At Castelluccio di Norcia snowfalls are frequent, but how much snow builds up depends on the weather systems. In February 2024, for example, the winter was unusually mild, and snow only occasionally whitened the Vettore and the plain.

When there is snow on the ground and no wind, the cold can become extreme. In winter the Castelluccio weather station records very low minimum temperatures.

Provincial road 477, which links Norcia to Castelluccio, can be closed because of snow. In March 2026 avalanches from the Vettore forced the closure of the stretch between Pian Grande and Forca di Presta. Avalanche risk often returns in this area: before a hike it is worth checking the Sibillini avalanche bulletin (bollettino valanghe).

With enough snow, the loop trails on the Pian Grande (Piano Grande) or on the nearby Pian Piccolo are suitable even for those with little snowshoeing experience. For cross-country skiing there are trails on Pian Perduto.
