Skiing and climate
What does a warmer world mean for skiing?
Skiing faces an uneven future: snow supply becomes less reliable as the world warms, while geography and snow management change how much that matters. A European study finds a large difference between +2°C and +4°C worlds. Neither scenario is a forecast for your next holiday or a count of resorts destined to close.François et al. · European skiing
Ask how much of a ski area stays usable in a difficult winter, as well as how high its summit is.
How the European risk changes
| Global warming | No snowmaking | 50% slope snowmaking |
|---|---|---|
| +2°C | 53% | 27% |
| +4°C | 98% | 71% |
What does snow-supply risk actually measure?
The risk framework compares future snow conditions with unusually poor seasons in the 1961–1990 reference period. The study's warming levels describe the global climate, rather than a temperature increase measured at every mountain. This matters because a percentage needs its definition before it becomes useful.INRAE · regional ski results
For a skier, separate three questions: whether enough snow exists, whether the terrain you need opens, and whether the resort remains economically viable. A single risk category cannot answer all three. Read it as a reason to investigate exposure, especially when an appealing headline appears to offer a definite end date for skiing.
Can snowmaking keep a season dependable?
Snowmaking reduces the modelled risk, but the comparison assumes equipment on half the slopes. It also involves water and electricity demand. The table describes that specific adaptation experiment; it does not certify each resort's capacity, water availability or operating choices.François et al. · European skiing
A useful question for an operator is which links and beginner areas are supported, and what happens during a mild spell. Ask for an explanation of the actual network rather than treating the presence of snow cannons as a complete answer. For seasonal work, ask how variable opening dates affect the role and accommodation arrangements.
Is choosing a higher resort enough?
Elevation belongs alongside region and terrain when interpreting snow reliability. The IPCC mountain assessment also describes glacier retreat and thawing permafrost, so a higher location does not remove every climate pressure. Snow cover is only one part of a mountain's changing environment.IPCC · mountain futures
Our planning suggestion is to examine the parts of the mountain you expect to use: the learning area, the return run, the connection between sectors and the route from your accommodation. Compare those details with current operations. A summit photograph is much less informative when your everyday skiing depends on a different elevation band.
What can this tell me about next winter?
It establishes a long-term planning context. It cannot decide which week will be snowy. Keep a dated seasonal outlook, the short-range forecast and the long-term climate assessment as separate tools. A snowy fortnight does not invalidate a warming climate, and a poor holiday does not by itself measure a regional climate trend.
When comparing destinations, retain the study year and baseline beside the statistic. Do not add percentages from different papers, or translate a regional number into a promise about one village. Choosing flexible dates and understanding a destination's alternative activities are practical responses to uncertainty, not guarantees of better snow.
Use the right evidence for the decision
Start with this guide for long-term context, the regional guides for differences within Europe, and current conditions for the coming days. If you are choosing a seasonal job, make the employer's actual operating plan part of the conversation. PeakWave's climate summary does not replace that local information.
Sources, method and updates
The European comparison uses François et al. (2023), supported by the research team's INRAE explanation. Snow-supply risk and economic viability are different outcomes. We preserve the modelled snowmaking assumption and do not infer resort-level probabilities. Practical planning suggestions are PeakWave's interpretation.

- François et al. · European skiing
2,234 resorts across 28 European countries at +2°C and +4°C global warming. Very high snow-supply risk is a study-defined hazard, not a probability of resort closure. Adaptation assumes snowmaking on 50% of slopes.
- INRAE · regional ski results
Research team's regional explanation of François et al. Percentages at +2°C; the French Alps value without snowmaking is approximately one third.

Edition history and next editorial review
: First edition. Added the European warming-level comparison, adaptation assumptions and guidance on separating climate context from next winter's forecast.
Next planned editorial review: , to check newly published annual assessments and relevant research. This is an editorial target, not an automated update or a promise of new data on that date.
