Big White BC
The short answer: PassCast projects a median of 257" at Big White for 2026-27 — 87% of a typical season — with a skiability rating of 53/100, ~10 powder days, and Nov–Dec as the prime window. Updated daily from 10,000 simulations.
80% of simulated seasons land between 200" and 336". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.

What's driving this forecast
The 2026-27 season is simulated by resampling Big White'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.
El Niño displaces the Pacific storm track south of BC and raises freezing levels; strong La Niña months out-snow strong El Niño months by ~30% at La Niña-favored interior areas, though Sun Peaks and Red are nearly ENSO-neutral. Applied as a -4% tilt at partial weight.
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 readInterior BC · from the 2026-27 outlook
Interior BC skis best in La Niña, and a strong El Niño sends the storm track south while raising freezing levels — strong La Niña months out-snow strong El Niño months by ~30% at favored spots, though Sun Peaks and Red are nearly ENSO-neutral. 2023-24's thin, warm early winter at Revelstoke is a plausible template. Expect below-average totals, more mid-elevation rain events, and the safest bets in high-alpine terrain from February onward. A down year, not a disaster.

Big White 2026-27: straight answers
- How much snow will Big White get in the 2026-27 season?
- PassCast's latest 10,000-run simulation (reseeded 2026-07-10) puts the median at 257 inches — 87% of a typical season at Big White — with 80% of outcomes between 200 and 336 inches. The forecast blends Big White's own 36-season ENSO analog record with NOAA's seasonal outlook and the ECMWF SEAS5 ensemble.
- Is a season pass worth it for Big White in 2026-27?
- Big White is not on Epic, Ikon, or Mountain Collective for 2026-27 — budget about $115 per peak-window day ticket, or check the resort's own multi-day products.
- When is the best time to ski Big White in 2026-27?
- Nov–Dec is the prime window — the deepest contiguous stretch of the ENSO-conditioned season at Big White. Month-by-month medians are charted on this page.
- How reliable will the snow be at Big White this season?
- The simulation gives Big White a 27% chance of beating its typical season and a median of about 10 six-inch-plus powder days. Its skiability rating is 53/100 (“Solid skiing expected”), updated daily.
