What we look for at Mt. Umunhum

Wind direction

SSW (200°) → WSW (250°)

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

Ideal speed

8–15 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.

Advanced, access-sensitive launch on Mt. Umunhum in the Sierra Azul preserve, Santa Cruz Mountains (~3,350 ft). Two possible facings: a SW launch that lines up with the afternoon WSW-SW sea breeze (primary) and a NE launch for morning/offshore days — only one works on a given day. Expect rotor and turbulence behind the summit and over the lee terrain; fly it in steady light-to-moderate flow, not strong wind. Confirm launch location and current access with Wings of Rogallo and local pilots first.
