UNDERSTAND THE WHOLE MOUNTAIN
Weather at the base can differ from conditions higher up. Firn brings elevation-based forecasts together so you can compare snowfall, wind and temperature before your ski trip.

CHOOSE YOUR WINDOW
The Snow Score brings forecast conditions into a single rating. Use it alongside the suggested three-hour window to compare times for your outing. Both are planning aids based on weather data; they do not guarantee powder or safe conditions.

PLAN YOUR NEXT POWDER DAY
Browse the seven-day Powder Calendar, compare upcoming days and keep your favorite mountains close. Whether you ski or snowboard, Firn makes it easier to follow fresh-snow potential and changing mountain weather.

FOLLOW THE PLACES THAT MATTER
Save resorts or your own private spots and set the forecast alerts you want. Get a clearer explanation with Mountain Verdict, an AI-generated summary of the available forecast. Feature availability depends on your plan, location and data coverage.
