What we look for at Nike Site

Wind direction

W (270°) → NNW (340°)

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.

Alpine ridge launch near Nike Site Summit on Mt. Gordon Lyon in Arctic Valley, on the eastern edge of Anchorage, flown by the Arctic Air Walkers. Works best in W-to-NW winds around 7-12 mph with light gusts; watch for building afternoon thermals, valley flow, and lee rotor if the wind backs to the S/SE. Access is sensitive - the summit sits on JBER military land with restricted public access, so confirm legal launch and landing with the Arctic Air Walkers first. P2+ pilots comfortable in alpine air; best in stable mornings or evening glass-off.
