How it works

The powder score

Resorts are ranked by one number: how much of the next 7 days' snow should actually be good to ski. Wet or rainy days count for less, so a big dump that lands as rain won't top the list. The plain 7-day total is shown alongside it.

The badges

Each day gets a call on what the snow will be like where you actually ski:

• PowderCold, dry snow — the stuff powder-hounds chase.
• SnowAll snow, but falling near freezing — denser and wetter. Great cover, not champagne.
• MixedRain mixes into the snowfall — snow up high, ice or rain lower down.
• RainMostly rain. Rain days show orange throughout the app.

Quiet weeks get No snow during the ski season — a dry spell, not closed lifts — and Off-season in summer.

Reading the chart

Bars are each day's snowfall. The amber line is the freezing level — the altitude where 0 °C sits — plotted against the resort's dashed base and summit lines. It's context, not a verdict: snow survives a few hundred metres below the freezing level, so a line near the summit doesn't mean rain to the top.

Days past the first week are drawn dimmed — forecast skill drops off, so read them as a trend, not a promise. The last 7 days figure is what the weather model says already fell, not a resort report.

The data

Forecasts come from Open-Meteo (CC BY 4.0), refreshed several times a day. Japan is covered by a high-resolution local model; New Zealand and Australia use global models, so treat amounts there as indicative rather than precise. Resort locations and elevations come from OpenSkiMap / OpenStreetMap (ODbL).

No lift status or resort-reported conditions — check the resort's own snow report for measured base depth.
