Bormio IT
The short answer: PassCast projects a median of 151" at Bormio for 2026-27 — 109% of a typical season — with a skiability rating of 50/100, ~4 powder days, and Nov–Dec as the prime window. Updated daily from 10,000 simulations.
80% of simulated seasons land between 95" and 208". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.

What's driving this forecast
The 2026-27 season is simulated by resampling Bormio's historical seasons weighted toward El Niño analog years. NOAA CPC El Niño Advisory (June 11, 2026): El Niño conditions are present and expected to strengthen into winter 2026-27, with a 63% chance of a very strong event (Niño3.4 ≥ +2.0°C) during Nov-Jan. CPC DJF strength odds: very strong 46%, strong 33%, moderate 16%. IRI (June 22) concurs at 98% El Niño for DJF. Latest observed ONI (AMJ 2026): +1.0.
The 51-member SEAS5 seasonal forecast puts Nov–Jan snowfall at this grid point at 118% of its ERA5 normal (ensemble mean 92", spread 66–127"). Applied as a +5% 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.

Bormio 2026-27: straight answers
- How much snow will Bormio get in the 2026-27 season?
- PassCast's latest 10,000-run simulation (reseeded 2026-07-10) puts the median at 151 inches — 109% of a typical season at Bormio — with 80% of outcomes between 95 and 208 inches. The forecast blends Bormio's own 36-season ENSO analog record with NOAA's seasonal outlook and the ECMWF SEAS5 ensemble.
- Is a season pass worth it for Bormio in 2026-27?
- Bormio is not on Epic, Ikon, or Mountain Collective for 2026-27 — budget about $68 per peak-window day ticket, or check the resort's own multi-day products.
- When is the best time to ski Bormio in 2026-27?
- Nov–Dec is the prime window — the deepest contiguous stretch of the ENSO-conditioned season at Bormio. Month-by-month medians are charted on this page.
- How reliable will the snow be at Bormio this season?
- The simulation gives Bormio a 63% chance of beating its typical season and a median of about 4 six-inch-plus powder days. Its skiability rating is 50/100 (“Solid skiing expected”), updated daily.
