Any resort, at a glance

Tap a pin. Temperature, wind up top and snow on the ground, then when the snow is coming, day by day.

Every resort gets a card: what's on the ground, what's coming day by day, and the avalanche danger.

The Mt. Bachelor card in a blizzard: 17°F up top and 28°F at the base, wind 14 mph gusting 28, 49 inches on the ground, snowing today (24 inches up top) and 50 more inches by Friday.
The card's day strip: 24 inches today and 34 tomorrow at the summit, 73 inches in the next 7 days, snowing now and heaviest Sunday morning.

Who has the best snow?

Check at a glance. Every resort's pin is coloured by its snow, from grey to the rarest orange: fresh snow, the week ahead, the season and more.

Our promise

Weather apps have a habit of taking things away once you rely on them. We're writing down now what we will never do, and we'll keep it.

  1. Free stays free

    Free forever: the past and present everywhere (radar, snow that fell, snow on the ground, every resort card with its full 7-day snow numbers, avalanche danger).

  2. Premium adds more features and layers

    Premium gives you the forecast maps past tomorrow and our deeper reads of the week ahead. From launch day, nothing free moves to paid.

  3. Small ads, never in the way

    The free app and site carry one small banner, never over the map controls or a resort card. No pop-ups, no full-screen or video ads, ever, and premium has none. There are no ads yet: the banner arrives with the store apps and 1.0, and we'll say so here first.

  4. Your price is locked

    Existing subscribers never pay more.

  5. Your location stays yours

    We never sell or share your location.
