Attitash NH
The short answer: PassCast projects a median of 116" at Attitash for 2026-27 — 98% of a typical season — with a skiability rating of 42/100, ~5 powder days, and Jan–Feb as the prime window. Updated daily from 10,000 simulations.
80% of simulated seasons land between 70" and 158". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.

What's driving this forecast
The 2026-27 season is simulated by resampling Attitash'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.
Northern New England saw below-average snow in >90% of moderate-to-strong El Niño winters; the warm signal is more reliable than the snow signal, and coastal storm tracks can flip individual winters. Applied as a -6% 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 readNortheast · from the 2026-27 outlook
Strong El Niño is a torch for New England: 2015-16 was the warmest, least-snowy winter in modern Northeast ski history, and 2023-24 wasn't much kinder. The counterweight is the amped subtropical jet, which can detonate coastal bombs when cold air is available — the hope is a 2009-10-style big-storm pattern rather than a 2015-16 washout. Plan for below-average natural snowfall and heavy snowmaking reliance, with genuine boom-or-bust nor'easter upside: one 30-inch weekend can rescue a lean year.

Attitash 2026-27: straight answers
- How much snow will Attitash get in the 2026-27 season?
- PassCast's latest 10,000-run simulation (reseeded 2026-07-10) puts the median at 116 inches — 98% of a typical season at Attitash — with 80% of outcomes between 70 and 158 inches. The forecast blends Attitash's own 36-season ENSO analog record with NOAA's seasonal outlook and the ECMWF SEAS5 ensemble.
- Is a season pass worth it for Attitash in 2026-27?
- Attitash is on Epic Pass, Epic Local for 2026-27. At roughly $135 for a peak-window day ticket, the Epic Local ($829) breaks even in about 7 days here. PassCast's simulator on this page runs your planned days through all 10,000 simulated seasons for a full verdict.
- When is the best time to ski Attitash in 2026-27?
- Jan–Feb is the prime window — the deepest contiguous stretch of the ENSO-conditioned season at Attitash. Month-by-month medians are charted on this page.
- How reliable will the snow be at Attitash this season?
- The simulation gives Attitash a 48% chance of beating its typical season and a median of about 5 six-inch-plus powder days. Its skiability rating is 42/100 (“Selective — time it well”), updated daily.
