80% of simulated seasons land between 127" and 235". Reseeded daily as ENSO observations, CPC outlooks, and SEAS5 runs update.
10,000 simulated 2026-27 seasonsENSO-weighted resampling of 36 real seasons (1990–2026) at Hemsedal, tilted by the live seasonal outlook
Highlighted bars span the middle half of outcomes (P25–P75). The yellow dashed line is a typical season — the median of the last 36 at this mountain.
What's driving this forecast
The 2026-27 season is simulated by resampling Hemsedal'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.
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 readScandinavia · from the 2026-27 outlook
Nordic winters answer to the NAO, not the tropics — and the NAO is unpredictable at seasonal range. Sweden's Åre and Norway's Hemsedal/Trysil run cold enough that precipitation usually falls white regardless; Finnish Lapland (Levi, Ruka) is the most temperature-secure skiing in Europe. Treat 2026-27 as a normal Scandinavian lottery: no El Niño excuse, no El Niño boost.
