Mount Rubidoux ("The Rock") is a small ~1181 ft MSL boulder hill in Riverside, CA, listed as a recognized free-flight spot but with no detailed local-club/USHPA site guide found online. Wind window is inferred from the paraglidingEarth orientation hint (SW/W/NW octants work) plus the consistently westerly prevailing/forecast flow at the site (Windfinder shows ~238-274 deg sea-breeze westerlies). IDEAL: wind FROM the W quadrant, roughly 225-293 deg (SW through WNW), straight into the launch face. MARGINAL/edge: ~203-315 deg (SSW to NW) where the wind becomes cross. Treat as a small ridge-soaring / kiting / low-airtime training-style hill rather than a big thermal site: light-to-moderate sea-breeze conditions only. Outside the SW-NW arc the lee/rotor side makes it unflyable. Best window is typically afternoon when the onshore/sea-breeze westerly fills in. Speed and gust figures are conservative estimates, not club-published numbers. Rating/access: SoCal sites generally require USHPA membership and an appropriate rating (P2+ for a hill like this); confirm with local pilots/Crestline Soaring Society before flying. Confidence LOW: no explicit club guide numbers were located; arc derived from orientation hint + prevailing wind data.
