About

Live snow intelligence for the mountains you love.

Snowwatcher is a live ski companion for season 26/27: 570+ resorts with Snowsure scores, powder alerts, weekend picks, forecasts, and webcams. This guide is the short list in France, Andorra, Italy, Austria, and the United States. Each card opens that mountain: the snow, the graded runs, the lifts, the passes, and the places.

How fresh is the data?

Weather and Snowsure refresh regularly. Snow depth, temperature, and the coming days come from Open-Meteo. Snowsure scores and the full forecast come from SnowSure. Graded runs and lifts come from the Snowwatcher catalog. Webcams are live when the resort publishes them. Pass prices are the catalog rates, plus any newer figure saved for that resort.

Data and attribution

Snowwatcher combines trusted snow, weather, and map providers.

  • SnowSure. Resort snow scores and the full forecast.
  • Open-Meteo. Temperature, wind, snow depth, and the days ahead.
  • MapTiler and MapLibre. The piste map.
  • The wider map also uses Copernicus satellite snow cover, OpenWeather, and OpenStreetMap places.

The photograph

Summit, vertical, annual snow, and the day the season closes. Explore the Mountain opens the piste map.

The piste map

Runs are drawn in their colours. Click one and its card stays on the map: grade, length, and drop. The control at the top right fills the screen.

Today

Now, Snow, Snowsure, and Lifts sit under the map. Snowsure reads low, middle, or high. Lifts follow the catalog: closed for the season, or open.

Snow on the ground

Depth leads, with the past seven days, the next fourteen, and the wind. Full forecast opens the Snowsure report, including past winters as a bar chart.

Weather

The Weather card opens past days and the forecast. The period buttons change the chart, at the resort's own coordinates.

Lifts

The Lifts line is how many the catalog lists. The lifts page groups the names by type. It is the lift map, not a live queue.

Passes

The small card shows the adult day and the adult week when the catalog has them. A child rate and a family rate appear only when they have been saved. This guide does not sell passes.

Food and drink

A place opens its card: the address, the hours, the phone, the email, a description, and a photograph when they are listed. All places opens the full page, and each card there opens the same details.

Webcams

The webcam card plays the picture or the video. View all webcams opens the resort's own page when an address has been saved, and this guide's page otherwise.

Emergency numbers

The red Emergency link opens the Emergency numbers panel. 112 is listed on every resort. In the United States, 911 is first. Local lines are listed when they have been saved. Resort location is the mountain. My location reads this phone when you allow it.

The guide

The last section is the catalog overview: the domain, the runs, and the season in one place.

Every mapped run

Browse all runs lists the pistes. Filter by grade, search by name, and sort by name, length, steepness, or drop. A run with no name is Unnamed piste. Click a row for a map of that line. If the catalog has no trace, the window says so.

On a phone

The bar at the bottom is Resort, Runs, Weather, Emergency, and More. Emergency opens the numbers. More holds the lifts, the passes, the food, the webcams, the guide, and Change resort.
