With much talk of a potential upcoming La Niña winter being forecasted, we thought we’d dive a little deeper and see how previous La Niña & El Niño patterns have affected Hokkaido over the last decade.
As you can see from the data comparison below, we have seen good snowfall totals in La Niña pattern winters, but there are definitely more complexities at play, with big totals also seen in both neutral and El Niño patterns over this time.
Snow Totals/Weather Patterns Niseko and Furano 2012-2022
(Resort base area – upper mountain can receive up to x3 these totals)
Currently the Japan Meteorological Agency (JMA) has predicted a 90% likelihood that La Niña conditions will continue through the coming winter, dropping to 60% in spring. For those of us planning to be in Hokkaido and Northern Japan, this means the potential for above-average snow totals.
As outlined by Ronan Maguire, Whiteroom Lead Avalanche Forecaster:
The reason for this is that a La Niña pattern results in cooler-than-average surface temperatures across the equatorial central Pacific Ocean and a rising of the ocean temperatures adjacent to Southeast Asia, which is generating moist air.
All of this moist air tends to create blocking high-pressure systems on the East coast of the Indochina peninsula – Thailand, Cambodia and Vietnam, etc. These highs then push the cold prevailing westerly winds further North which means we have warm moist air meeting a cold air flow from Siberia which then sees those moisture-rich clouds dump a lot of snow across Hokkaido and the Tohoku region.
These patterns also go hand in hand with colder temperatures and less sunny days in the region this winter, but the skiing and riding should be epic!
Of course these are long-range forecasts and models, and not to be taken as gospel, but things are looking positive at this stage. In either case, an average winter in Japan is nothing short of amazing, which is why we keep going back!
For all of you fellow weather nerds out there, the following chart may also pique your interest; all recorded historical El Niño and La Niña Events, defined by Sea Surface Temperature (SST) deviation, in Japan since 1950.
One thing is certain, after a such a long wait to get back, and less than 30 days until resorts begin to open across Hokkaido and Tohoku we are excited to welcome you all back to Japan soon!
We still have places available on our early and late season guided powder tours, and a few spots scatterd through the peak winter period.
Get in touch if you’d like to join us for the Return to Japow!
