What we look for at Blue Rock (Vallejo)

Wind direction

WSW (245°) → NW (308°)

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

Ideal speed

7–12 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.

A west-facing ridge soaring site near Vallejo, flyable from about 245-308 degrees (WSW-WNW), best straight west at 7-12 mph. Anything over ~18 mph makes the LZs turbulent. Hazards: a rock formation at the top of the slope (launch lower), rotor off orange-marked trees, and a venturi in the St. Johns Mine Road valley. Walk both LZs before flying - they hide rocks, spiky cardoons, and barbed wire. P3 encouraged; season runs roughly March-October, smoothest spring and fall evenings.
