When the live forecast shows steady cold north-westerly flow with snow stacking overnight, that is when the upper bowls and tree runs deliver the refilling powder this mountain is built on. The catch is wind: the summit lift sits above the treeline and gets pulled down regularly, even on big snow days, so a forecast with strong ridge winds usually means lapping the mid-mountain chairs instead of chasing the top. Freezing level matters too. As long as it stays well below the 260 metre village base, the snow stays light. Chase a storm when winds are calm and cold; if winds spike, plan a tree day.
