The question comes earlier every year: when does it start? Here are the dates already announced for winter 2026/27 – and, because it is more honest, the context on what such a date is worth in August.
The announced dates
These are the dates the resorts have communicated. They come with the usual proviso: all of them assume enough snow.
| Date | Resort | What opens |
|---|---|---|
| 24 October 2026 | Diavolezza | glacier piste; until 15 November only Wed, Sat, Sun |
| 29 October 2026 | Engelberg-Titlis | glacier (instead of 24 October) |
| 31 October 2026 | Saas-Fee | winter season (instead of 1 November) |
| 1 November 2026 | Zermatt | winter season, Sunnegga/Rothorn and Gornergrat only from 28 November |
| 6 November 2026 | Mölltal Glacier | pistes 8 and 9, depending on snow conditions |
| 7 November 2026 | Glacier 3000 | glacier, daily until 30 April (instead of 8 November) |
| 7 November 2026 | Verbier / 4 Vallées | Lac des Vaux, at first at weekends (instead of Mont-Fort) |
| 13 November 2026 | Davos Klosters | Parsenn, expected (instead of 6 November) |
| 15 November 2026 | Engelberg-Titlis | Stand / TrĂĽbsee (not rechecked by us) |
| 21 November 2026 | Corvatsch | winter season (confirmed by the lift company) |
| 21 November 2026 | Jungfrau Ski Region | Grindelwald / Wengen, if snow and weather conditions allow (instead of 28 November) |
| 21 November 2026 | St. Moritz | Corviglia (not confirmed by us) |
| 21 November 2026 | Andermatt-Sedrun | Gemsstock (not confirmed by us) |
| 28 November 2026 | LAAX | winter season, daily from 5 December (confirmed by the lift company) |
| 4 December 2026 | Villars-Gryon-Diablerets | winter operations |
| 5 December 2026 | Adelboden-Lenk | winter operations |
| 5 December 2026 | Aletsch Arena | winter operations |
| 18 December 2026 | Obersaxen Mundaun Lumnezia | winter operations until 4 April |
Corrected on 7 November 2026: Several dates in this table were out of date. The Titlis opened on 29 October (not the 24th), Saas-Fee starts on 31 October, Glacier 3000 on 7 November (not the 8th), Davos Parsenn is expected on 13 November (not the 6th), Verbier opens with the Lac des Vaux at weekends (instead of “Mont-Fort”) and the Jungfrau Ski Region on 21 November (not the 28th). New in the table are Mölltal, Corvatsch, LAAX and Obersaxen. For St. Moritz and Andermatt we could not confirm 21 November with the lift companies. The count below (four, nine, 72) is the state of August and stays as such.
Corrected on 2 October 2026: For Zermatt this table said “Sunnegga / Rothorn” on 1 November. According to Zermatt Bergbahnen, the winter season starts on 1 November, while Sunnegga/Rothorn and Gornergrat only open on 28 November. Corrected on 7 October: the Titlis opens its glacier on 24 October instead of 10 October, and Diavolezza runs from 17 instead of 18 October, until 15 November only on Wednesdays, Saturdays and Sundays. Corrected on 18 October: Diavolezza postponed its start on 13 October, because of high temperatures, probably to 24 October. The continuously updated dates for every resort are on Opening dates.
The rest of the 85 resorts in our overview have announced nothing yet. That is normal: smaller areas deliberately avoid committing in August, because a postponed opening costs more than a late announcement.
The pattern: altitude decides, not region
More interesting than the individual dates is the distribution. Of the 85 resorts in our dataset, the overwhelming majority does not start until December:
The four October resorts – Zermatt, Saas-Fee, Diavolezza, Engelberg-Titlis – have one thing in common: they all have a glacier. Of the nine November resorts, the median ski terrain reaches 2,971 metres. The 72 December resorts are everyone else.
This is not coincidence but a hard physical limit. An October or November start needs either glacier ice, which supports the snow cover from below, or terrain high enough for snowmaking to run reliably in November. Few places in Switzerland have either.
How binding is such a date?
Honestly: moderately. A date announced in August is a statement of intent, not a commitment. What actually decides it only becomes clear in October and November:
- Cold, not snow. Most resorts open on machine-made snow. That needs several consecutive nights below roughly minus 3 degrees wet-bulb temperature. A mild November delays openings faster than a dry one.
- Wind. Snowmaking in strong wind is wasted; the snow lands beside the piste.
- When the first cold spell arrives. Catch two cold weeks in late October and you have a base that survives the November föhn. Miss them and you open later, whatever the August announcement said.
What the coming winter might look like is in our season-start outlook for 2026/27. In short: no serious statement about the first snow can be made in August, and anyone claiming otherwise is selling something.
What the summer of 2026 has to do with it
One point matters especially this year. Glacier resorts normally open early because they have a glacier. That very precondition is what the hot summer of 2026 has been attacking. Zermatt halted summer skiing at the end of July, and the glacier loss day fell as early as 29 June.
This does not mean the 1 November winter start is in danger – the winter season depends on the snow cover, not on the previous summer’s glacier state. But it does mean the early dates deserve closer watching than usual this year. A glacier still bare in October needs more fresh snow than one carrying a layer of firn.
The practical advice
If you want to ski in October or November, plan late. Do not book weeks ahead; decide the week before, once the lift companies have actually released the installations. In those early weeks only individual runs are usually open, not the whole area.
If you are planning the February holidays, December is safe. Of the 85 resorts, not one plans to open only in January.
If you want snow rather than a date, look at altitude. A resort reaching 3,000 metres is in a different position in December from one topping out at 1,800 – check the resort pages, where the altitude band and season months are listed for every area.
We will update this overview as further resorts announce their dates.
Update, 10 August 2026: we have added Braunwald (GL) to the dataset, bringing it to 86 resorts. Braunwald opens in December, so the 72 December starters become 73. The argument of the article is unchanged, but the figures in the chart still refer to the state on 4 August. The continuously updated version is on our opening dates page.
Update, 19 August 2026: and back down to 85. Bergbahnen Destination Gstaad have told us that Zweisimmen is not a ski area of its own but the lower part of Gstaad, whose 200 kilometres of piste already include it. We had counted it twice. That takes the 73 December starters back to 72.
As of 4 August 2026. All dates without guarantee and subject to snow conditions; the lift companies’ own information takes precedence. Sources: season calendars from skiinfo.de and schneehoehen.de, lift company announcements, our own dataset for the distribution across all 85 resorts.
