Chile 🇨🇱
Character
Further south, sits between the arid central Andes and wet Patagonian influence. Lower base elevation adds La Niña risk. Geothermal hot springs make it a unique winter destination regardless of snowfall depth.

Trip Planning

Which Resort for Your ENSO Year?

☀️ El Niño Year

Go Deep,
Go Central

El Niño brings the storm track right through the central Andes. Any Chilean resort near Santiago is primed for a banner season. This is the year to prioritize terrain over consistency.

Top picks for El Niño:

  • #1 Portillo — lake-side magic, max powder
  • #2 Valle Nevado — largest resort, big terrain
  • #3 Las Leñas — driest powder, steep lines
  • #4 La Parva — linked with Valle Nevado
🌤 Neutral Year

Choose Elevation,
Watch Drought

Neutral years are the most uncertain. The Mega-Drought index matters most here. High-base resorts (Valle Nevado, La Parva) have structural depth advantages over lower options.

Top picks for Neutral:

  • #1 Valle Nevado — highest reliable base
  • #2 La Parva — excellent high-altitude terrain
  • #3 Cerro Catedral — Patagonian buffer
  • #4 Las Leñas — if timing early season
❄️ La Niña Year

Go South,
Go Patagonia

La Niña suppresses central Andes moisture. The further south, the more protected. Cerro Catedral's Patagonian westerlies are largely decoupled from ENSO — it's the safe harbour.

Top picks for La Niña:

  • #1 Cerro Catedral — ENSO-proof, huge terrain
  • #2 Nevados de Chillán — intermediate buffer
  • #3 Valle Nevado — high base limits damage
  • #4 La Parva — elevation compensates partly
