Bald Mountain · 9,150 ft · 48-hour past & forecastWind roses show how often wind blows from each direction. Longer petals mean wind came from that direction more frequently. Color shows speed: blue is calm, darker blue is moderate, red is strong.
The timeline arrows point in the direction the wind is blowing toward — the way snow would drift. If you face the direction the arrow points, the wind is at your back.
For skiing: Wind-loaded slopes (leeward side) accumulate deeper but less stable snow. The rose helps identify which aspects have been wind-affected and which will be affected next.
Speed guide: Under 15 mph is comfortable on a chairlift. 15–30 mph causes exposed lifts to slow or hold. 30+ mph typically means upper lift closures and dangerous ridgeline conditions.
