What we look for at Sieben Ranch

Wind direction

WNW (285°) → N (350°)

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

Ideal speed

6–15 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.

Foothills launch in the Sieben Ranch / Lyons Creek area north of Helena (~5,000 ft), listed in aggregator databases as W/NW/N-facing. No club guide with real numbers exists, so the NW-quadrant window is inferred. Expect thermic midday cycles, gust fronts, and lee rotor if the wind backs into S/E; morning or evening is smoother. This is private ranch land - get landowner permission and a local briefing from the Montana free-flight community before flying.
