Lotte Arai El Niño rank & forecast
Lotte Arai ranks #398 of 488 SnowSure resorts — Tier E, −14% in strong El Niño winters.
Tier E — Deep timing play — aim late winter: Strong El Niño winters ran clearly below this resort’s own baseline (≤ −8%). Still skiable — schedule late season; one storm cycle can beat the climatology.
Strong-event signal: −14% vs this resort's 30-yr avg
In the three strongest El Niño winters on record ('97-98, '15-16, '23-24), Lotte Arai averaged -14% 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 -34%, '15-16 -47%, '23-24 +40%. One caveat that always holds: a single storm cycle can beat the climatology.
