    Understanding the Snow Report

    Snow Measurements

    Base depth, summit depth, and recent snowfall are the core numbers to watch. At Grandeco, summit conditions (1590m) can differ noticeably from the base, so we break both out separately rather than showing a single average.

    Weather Conditions

    Snow quality tracks closely with temperature and wind. We surface both alongside the snowfall data so you can judge whether conditions at Grandeco are holding up or starting to soften.

    Data Sources

    We pull Grandeco's conditions from on-the-ground mountain reporting, then layer in forecast data so you get a fuller picture than either source alone. The mountain is served by 4 lifts, including 3 quad chairlifts and a gondola.

    When to Check

    Snow reports are typically updated early morning and late afternoon. For the most current conditions, check back regularly, especially if a winter storm is approaching. With Grandeco's season running from Dec 5, 2025 to Mar 29, 2026, checking daily during a storm cycle gives you the clearest read on new snow.
