- How will El Niño affect Tomamu in winter 2026-27?
- El Niño Signal Rank: #438 of 488 SnowSure resorts · Tier E · strong-event signal -18% vs its own 30-yr average. In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Tomamu averaged -18% versus its own 30-year snowfall baseline. The honest read: this is the fleet's deepest timing play. The snow still comes — but in Japan the El Niño hit lands on the season's edges, not the heart of the sea-effect window. Point your winter 2026-27 trip at the mid-winter core (January to mid-February), stay flexible on dates, and watch our monthly scorecard. Analog winters: '97-98 -37%, '15-16 -6%, '23-24 -12%. One caveat that always holds: a single storm cycle can beat the climatology.
