What we look for at The Dunes

Wind direction

W (270°) → N (360°)

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

Ideal speed

10–18 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.

Small dune-soaring site at the Koocanusa Sand Dunes near Eureka in far NW Montana — low relief on soft sand. Needs a steady west-through-north wind onto the dune face, roughly 10+ mph to stay up and best around 12–18; it gets sporty above the low 20s given the small dunes. Soft sand makes for forgiving launches and landings, suiting training and low-airtime soaring. The dunes are only accessible when reservoir levels are low, generally late March to late June. No club site guide — confirm access and conditions locally.
