Sipapu NM
80% of simulated seasons land between 99" and 221". 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 Sipapu, 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 Sipapu'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.
The mirror image of the PNW: the strongest positive El Niño snowfall signal anywhere (AZ Snowbowl MEI correlation +55%, Taos +29%), amplified in strong events. Applied as a +12% 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 readSouthwest · from the 2026-27 outlook
This is the US El Niño jackpot: a juiced subtropical jet trains storms across Arizona and New Mexico, and the strong-event record is emphatic — 1982-83 and 1997-98 rank among the snowiest winters ever in the region, and 2023-24 handed Taos a banner year. 2015-16 underperformed as storms tracked north — the standing reminder that analogs aren't promises. Still, the Southwest owns the continent's best odds of a well-above-average 2026-27.
