Weather for skiers

Date: November 2026 · Reading time about 6 minutes

On the mountain, the average temperature in the valley does not count, but the weather up there, in the hours when the lifts run. Those who know a few typical weather conditions read the forecast differently – and save themselves some gray, windy or icy days.

Foehn: mild, clear - and stormy

The Föhn is a foehn wind. Air flows over the Alps, descends into the valleys on the other side and warms up by about one degree per 100 meters of altitude. at southerly foehn – the more frequent variant in Tyrol, Salzburg and Bavaria – the moist air accumulates on the southern side of the Alps; in southern Tyrol it often rains or snows then. On the northern side it is mild, dry and the visibility is often excellent. Over the main Alpine ridge there often stands a cloud wall, the Föhn wall.

For the ski day, this means: On exposed peaks and ridges, the Föhn wind can reach storm force. At Patscherkofel near Innsbruck, gusts up to 107 km/h were measured during a Föhn event in October 2024. Upper lifts often remain stationary, while the valley is almost spring-like. The snow becomes soft in lower elevations or gets a cover, and at the top, the wind deposits snow on the lee slopes.

The foehn usually does not last long. If it breaks down, a front with west winds, cooling, and snow often follows on the northern side. The north foehn is the opposite: it brings cold air behind a cold front and mainly blows on the southern side of the Alps.

Inversion: Sun over the fog sea

Normally it gets colder with the height. At a inversion the pattern is reversed. On long, calm nights with high pressure, air near the ground cools and collects in valleys and basins. Above it, sinking air becomes warmer and drier. Low stratus often forms at the boundary and may persist for days in weak winter sunshine.

Below, gray, damp, and cold, above, bright sunshine and noticeably milder – this is the classic mountain sun over the fog sea. For skiers, this is often a gift. The catch: if you only look at the forecast for the valley town, you see fog and stay home. Therefore, pay attention to the values at mountain elevation and to how high the fog limit should be.

Diffuse light and whiteout

With thick cloud cover, snowfall, or wind-blown snow, the light between the snow cover and clouds is often scattered. It then comes from all directions, and shadows disappear. Skiers call this Diffuse light or flat light: ground waves, edges and depressions are hardly noticeable, although the view itself is not bad at all. In the extreme case, the Whiteout, even the horizon disappears - the ground and sky merge, distances can no longer be estimated and some people lose the sense of balance.

• Drive slower and stay near trail markers, trees or fences - they contrast.
• Forest trails are often more pleasant in low light than tree-free slopes.
• A lighter lens helps: ski goggles are classified according to EN ISO 18527-1 into filter categories from S0 (very light) to S4 (very dark); with low light, the lighter categories fit better.
• Stay together in the group. Sunglasses protect the eyes from UV rays, but not from loss of orientation.

Wind and lift operation

Lift operation depends more on gusts than on average wind speed. Sensors on cableway towers continuously relay measurements to the control station. Slowdown and stop thresholds are specific to the installation and its terrain. An SRF report gives typical examples of warnings around 40 km/h and alarms around 60 km/h. The operator makes the decision on site.

In practice, it first affects the high, exposed cable lifts and mountain gondolas. Even a windy day doesn't have to be a lost day: sheltered forest slopes and lower-elevation lifts often run on. The winds at the summit and the operator's lift status tell more than any weather app in the valley.

Cold and wind chill

Wind takes heat away from the skin. the Windchill indicates how cold the air feels on unprotected skin when windy. Since 2001, the weather services of Canada and the USA have used a common formula for this purpose. The values that can be calculated with this formula, for example, are:

Environment Canada describes wind chills of −10 to −27 °C as a moderate risk. Prolonged unprotected exposure may lead to hypothermia or frostbite. At −28 to −39 °C, exposed skin may freeze in 10–30 minutes, and at −40 to −47 °C in 5–10 minutes. Strong sustained winds can shorten that time. Cover your face, add a layer and take warming breaks on cold ski days.

Snowfall level and freezing level

The Freezing level is the height at which the air temperature is 0 °C. Falling snow does not melt immediately below it: The Snowfall level lies below it, typically 200–400 metres in humid air and sometimes around 1,000 metres in very dry air. Snow gradually becomes sleet and then rain across a transition zone. A resort may receive snow above that zone and rain on its valley run. Read more in New snow, snow depth and snowfall level.

Weather during lift hours

Kaiserwetter Ski shows valley, mid-mountain and summit forecasts, including gusts, sunshine and the freezing level. Its weather rating covers lift hours. Summit feels-like temperature combines wind and cold, snowfall during lift hours lowers the visibility rating, and the goggles and clothing guidance helps you prepare for those conditions.
