No club/USHPA site guide, pilot report, or explicit numbers were found for a launch named "Town of Prairie du Sac" (43.2564, -89.7749, 735 ft MSL). Wind window is INFERRED from the paraglidingEarth orientation hint only. The listed workable octants (NE, E, SE, SW, W, NW) omit N and S, which suggests low-relief / open-field terrain rather than a single strong ridge — consistent with a flat-to-gently-sloping site near the Wisconsin River valley (the Sauk Prairie area is known mainly for powered paragliding, e.g. Wisconsin Powered Paraglider, and RC slope soaring at nearby Cedar Ridge between Black Earth and Prairie du Sac, which is a SW-facing slope). Because the orientation spans two separated arcs, I picked the more contiguous western/NW arc (SW-W-NW, ~225-315) as the primary IDEAL and the eastern arc (NE-E-SE, ~45-135) as MARGINAL. Speed ranges are generic low-elevation foot-launch defaults (5-12 mph ideal, ~15 mph max base, gusts under ~18 mph), NOT site-specific. Treat all values as rough placeholders; verify with local pilots (Compass AirSports, Wisconsin Powered Paraglider) and the actual paraglidingEarth listing before flying. Typical Midwest hazards apply: thermic/gusty midday conditions in summer, possible rotor from trees/buildings on the lee side, and proximity to Sauk-Prairie Airport (91C) ~2 mi away — check airspace.
