Snow-Sure Skiing: The Resorts That Still Deliver in a Warm Winter

Snow-Sure Skiing: The Resorts That Still Deliver in a Warm Winter

Two snow reports, the same week, the same mountain range. One resort's lifts begin at 1,113 metres and its highest run tops out at 2,350; the other begins at 2,300 metres and reaches 3,230. In a cold winter the two look much the same on paper. In a warm one they are not comparable, and the number that separates them is the one at the bottom, not the one at the top.

Mild winters have become a planning variable rather than bad luck, and the resorts that keep delivering through them share four unglamorous characteristics: a high base, slopes that face away from the sun, a serious snowmaking plant, and enough water to run it. Glaciers enter the conversation too, less reliably than their reputation suggests.

Base Altitude Beats Summit Altitude

Resort marketing quotes the summit. A warm winter is decided lower down, at the altitude where rain turns to snow and where skiers have to get home at four in the afternoon. A resort with a 3,500-metre top station and an 800-metre village spends February running buses, because the bottom third of its terrain is grass.

Val Thorens is the clearest case in Europe: the whole village sits at roughly 2,300 metres, the highest in the Alps, with lift-served terrain from about 1,800 metres to 3,230. Tignes keeps its main accommodation around 2,100 metres in Val Claret and Le Lac. Obergurgl's village stands at 1,930 metres with slopes between roughly 1,795 and 3,080 metres, which has earned it a reputation among snow-watchers as the most snow-sure non-glacial resort in the Alps.

Aspect does the rest, and it costs the resort nothing. North-facing slopes take a fraction of the direct winter sun, so the snowpack consolidates rather than melting and refreezing into something closer to concrete. The Val Thorens bowl holds a great deal of shaded, north-facing terrain, and Obergurgl's runs are predominantly north to north-west. A north-facing slope behaves much like a south-facing one several hundred metres higher, which is why two resorts with matching altitude statistics can ski very differently in late March.

Where the Numbers Actually Land                                                                 

Gobba di Rollin runs reach 3,899 metres, and the Matterhorn glacier paradise station at 3,883 metres is Europe's highest cable car station. Zermatt's village sits at 1,620 metres, lower than Obergurgl's, which is why a warm week there can mean superb skiing on the Theodul glacier and a download on the last lift of the day. Cervinia, on the Italian side of the same glacier, starts 430 metres higher.

The climb is part of the logistics. A trip built around skiing in Val Thorens begins at a Tarentaise valley railhead below 500 metres and then gains roughly 1,800 metres of height over a 35-kilometre mountain road — about 40 minutes by car, comfortably over an hour on a scheduled bus, and longer again when the road is being cleared.

Glacier Skiing Is a Different Proposition

A glacier is not the insurance policy it appears to be. Midwinter, glacier terrain is simply high terrain and behaves accordingly. The difficulty is the shoulder seasons, when a glacier needs its own snow cover to be skiable at all: bare ice is dangerous, crevasses need bridging, the surface needs to refreeze overnight.

The trend in the data is not subtle. Bruno Abegg and Marius Mayer, writing in Frontiers in Human Dynamics in 2023, found that the share of summer days between May and October on which Alpine glacier ski areas were open fell from 27 per cent in 2011 to 14.8 per cent in 2022, with August operating days down 88.6 per cent. They cite the Grande Motte above Tignes, largely snow-free in summer 2022, where skiing was no longer possible after 1 July.

Two operations still run close to year-round. The Hintertux Glacier in Austria advertises skiing 365 days a year, from a valley station at 1,500 metres up to 3,250 metres, and Zermatt Bergbahnen makes the same claim for the Matterhorn ski paradise. For a December or an April trip, both are genuinely useful. In the headline weeks of January and February a high non-glacial resort with north-facing slopes will usually ski better, and will keep skiing in poor visibility, which glaciers rarely do well.

Snowmaking, Water and the Unglamorous Arithmetic

Snowmaking is where warm-winter reliability is bought, and two constraints govern it that investment cannot remove. The first is wet-bulb temperature: guns need cold, dry air, and a mild, humid airstream shuts them down however many are installed. The second is water. Covering a piste takes a great deal of it, which means reservoirs, abstraction licences and arguments with downstream users. Water rights, not snow guns, are the limiting factor in a growing number of valleys.

Coverage varies enormously by country. Industry figures for 2024 put snowmaking across roughly 90 per cent of Italy's piste area and about 75 per cent of Austria's. Obergurgl-Hochgurgl states that more than 90 per cent of its own runs are equipped, and Zermatt Bergbahnen reports that 80 per cent of its slopes are covered by glacier snow or machine-made snow.

What that buys is best stated by the people who modelled it. A study led by Samuel Morin and Hugues François, published in Nature Climate Change and summarised by its authors in a Carbon Brief guest post, assessed 2,234 European ski resorts against global warming levels. At 2°C of warming, 53 per cent faced a very high risk of scarce snow supply without snowmaking; with snowmaking on half their pistes, that fell to 27 per cent, while annual water demand for it rose by 8 to 25 per cent depending on the country. Those are the study's projections at specified warming levels, not forecasts for any particular season.

The Famous Names That Struggle

Kitzbühel is the standing example. The town sits at around 800 metres and no part of its terrain exceeds 2,000, so even a well-equipped snowmaking system fights the thermometer rather than working with it. Resterhöhe, above Pass Thurn, holds the best snow and can open early; the south-facing Kitzbühelerhorn is usually first to go patchy and can be bare late in the season. None of that diminishes the Hahnenkamm, but the Streif week and a half-term family trip are different propositions.

Megève is the French equivalent — village at 1,113 metres, top of the linked Evasion Mont-Blanc area at 2,350. Raw altitude misses two points in its favour: most of the skiing sits above 1,500 metres, and the lower slopes are grass rather than rock, so they need little depth to stay open. In a warm February the lowest runs still come and go.

Questions Travellers Ask

Does a high top station compensate for a low village?

Partly, and only for upper-mountain skiing. A high summit protects the best runs but does nothing for the ski home or the nursery slopes. The practical test is the altitude of the lowest lift that has to run for the resort to function normally, not the altitude of the highest.

Is a glacier resort the safest choice for early December?

Often, yes — glacier sectors tend to open first, and were the earliest reliable skiing long before snowmaking scaled up. The caveat is that early-season glacier terrain usually means a handful of runs at considerable altitude, exposed to wind and cloud, so a glacier opening is not a full ski area opening.

Can snowmaking rescue a genuinely warm winter?

It rescues a cold-but-dry winter very effectively. A warm, humid one is harder: guns need low wet-bulb temperatures to work at all, and a resort with full coverage and no cold nights ends up in much the same position as one with no guns.

The Short List

For a warm season, the resorts worth shortlisting share a profile rather than a nationality. 

·       Highest bases in the Alps: Val Thorens at about 2,300 metres and Tignes at around 2,100 metres in France; Breuil-Cervinia at 2,050 metres in Italy.

·       Best non-glacial record: Obergurgl-Hochgurgl, a 1,930-metre village with north-facing slopes and more than 90 per cent snowmaking coverage.

·       Dependable shoulder seasons: Hintertux and Zermatt, both skiing close to year-round, accepting that glacier terrain is limited and weather-sensitive.

·       Treat with care in a mild year: Kitzbühel, Megève and their peers below about 1,200 metres — fine resorts whose lower slopes depend on cold nights a warm winter does not supply.

The questions worth asking of any brochure are short: where does the lowest working lift start, which way do the slopes face, how much of the terrain is piped for snow, and where does the water come from.
