Val d'Isère-Tignes FR
The short answer: PassCast projects a median of 239" at Val d'Isère-Tignes for 2026-27 — 89% of a typical season — with a skiability rating of 58/100, ~11 powder days, and Nov–Dec as the prime window. Updated daily from 10,000 simulations.
80% of simulated seasons land between 173" and 351". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.

What's driving this forecast
The 2026-27 season is simulated by resampling Val d'Isère-Tignes's historical seasons weighted toward El Niño analog years, at 10% weight — the level that verified best for Alps in back-testing, with the rest drawn from unconditioned climatology. NOAA CPC El Niño Advisory (July 9, 2026): El Niño continues and will strengthen through the end of the year, with a 97% chance it persists through early spring 2027 and an 81% chance of a very strong event (Niño3.4 ≥ +2.0°C) during Oct-Dec — CPC notes it would rank among the largest El Niño events on record since 1950. Latest weekly Niño3.4: +1.2°C. IRI's July 20 update puts El Niño at 100% from JAS 2026 through JFM 2027 — DJF 2026-27 is now a certainty in the probabilistic forecast. Latest observed ONI (AMJ 2026): +1.0.
The 51-member SEAS5 seasonal forecast puts Nov–Jan snowfall at this grid point at 66% of its ERA5 normal (ensemble mean 100", spread 65–125"). Applied as a -9% tilt — experimental, heavily shrunk and clamped because seasonal models and reanalysis have different biases.
Day-to-day weather models have no skill this far out, so the near-term forecast contributes 0% weight today. The simulation leans entirely on ENSO-conditioned climatology — exactly what an honest seasonal outlook should do in summer. Weighting shifts toward live forecasts as opening day approaches.
The regional readAlps · from the 2026-27 outlook
The honest call for the Alps is that El Niño barely reaches them — ENSO explains little Alpine snowfall variance, and the season will be decided by the North Atlantic Oscillation, which no model reliably predicts months ahead. The nearest strong-Niño analogs cut both ways: December 2015 was record-warm and green across the northern Alps, while 2023-24 ran warm but storm-rich, burying high-altitude terrain as valley floors turned to rain. Treat 2026-27 as climatological odds with a modest warm-wet tilt: rain-line risk below ~1,500 m, decent totals up high, heightened chance of a slow December. Bet altitude, not region.

36% of five-day trips to Val d'Isère-Tignes would have included at least one morning after 6"+ of new snow (90% range 33–39%). In its leanest recorded winter it still produced 6; in its best, 27. See how that ranks →

Val d'Isère-Tignes 2026-27: straight answers
- How much snow will Val d'Isère-Tignes get in the 2026-27 season?
- PassCast's latest 10,000-run simulation (reseeded 2026-07-28) puts the median at 239 inches — 89% of a typical season at Val d'Isère-Tignes — with 80% of outcomes between 173 and 351 inches. The forecast blends Val d'Isère-Tignes's own 36-season ENSO analog record with NOAA's seasonal outlook and the ECMWF SEAS5 ensemble.
- Is a season pass worth it for Val d'Isère-Tignes in 2026-27?
- Val d'Isère-Tignes is not on Epic, Ikon, or Mountain Collective for 2026-27 — budget about $84 per peak-window day ticket, or check the resort's own multi-day products.
- When is the best time to ski Val d'Isère-Tignes in 2026-27?
- Nov–Dec is the prime window — the deepest contiguous stretch of the ENSO-conditioned season at Val d'Isère-Tignes. Month-by-month medians are charted on this page.
- How reliable will the snow be at Val d'Isère-Tignes this season?
- The simulation gives Val d'Isère-Tignes a 34% chance of beating its typical season and a median of about 11 six-inch-plus powder days. Its skiability rating is 58/100 (“Solid skiing expected”), updated daily.
