What we look for at Crested Butte Mountain

Wind direction

W (270°) → NW (310°)

The wind must blow from within this arc. Direction is the same for both wings.

Ideal speed

5–12 mph

Ceiling · Paragliding

≤ 19 mph base · gusts ≤ 23

Top of the range for paragliding (any rating) — switch wings up top to compare. Hang gliders hold roughly 10 mph more than paragliders.

West-facing "Brown's Launch" ramp at ~11,200 ft MSL on Crested Butte Mtn, run by the Crested Butte Soaring Society (CBSS). Ideal WNW flow 270-310; usable but cross/edge 250-325. AVOID southerly components: rotor off surrounding rocks, trees and ridges builds fast and the gust factor historically increases rapidly with any south in the wind. High-altitude thin, dry air can be very active; valley winds are a serious concern and flying is discouraged once valley wind ramps up (typically afternoon) - morning/early-day is generally calmer. PG ideal ~10 mph, usable 0-20; HG usable ~3-22. Typical gust factor ~5 mph. Advanced site: H4/P4 (H3/P3 with 20+ hrs/flights this season + check-off may be allowed); PG min 5:1 glide. CBSS guide-pilot accompaniment is mandatory; chairlift (Silver Queen) or 4x4 road w/ resort permit for access.
