How snow-sure is Guzet-Neige?
At Guzet-Neige, there was enough natural snow at Christmas in 10 of the 30 winters 1984/85–2013/14: at least 30 cm on 10 or more of the 14 days from 22 December to 4 January at mid-mountain (1,600 m; pistes 1,102–2,049 m). With snowmaking: 26 of 30. Climate models expect an average of 2.1 such Christmas days with natural snow there in 2041–2060 (RCP4.5), against 3.2 in 1986–2005. Source: Copernicus C3S, Ariège region.
More snowy Christmases than 19% of ski resorts in France and than 19% of the 690 European resorts on this site.
Christmas, year by year
Each box is one Christmas holiday (22 December to 4 January): the darker, the more days with at least 30 cm of natural snow. Outlined: at least 10 of the 14 days.
Christmases without enough natural snow (1,600 m): 1984/85, 1986/87, 1988/89, 1990/91, 1991/92, 1993/94, 1994/95, 1995/96, 1996/97, 1999/00, 2000/01, 2001/02, 2004/05, 2005/06, 2006/07, 2008/09, 2009/10, 2010/11, 2011/12, 2013/14.

What the numbers mean
- “Snow” here means at least 30 cm of snow depth in the model (Crocus) — enough to ski on, not just a white field.
- The model works per region (NUTS-3) and 100 m height band, not per piste; north-facing slopes, wind and glaciers are not taken into account.
- The reanalysis ends with the 2013/14 winter. More recent winters are not included.
- “With snowmaking” is the model's typical snowmaking, not the resort's actual equipment.
