No club/USHPA site guide with explicit numbers was found for this specific Lake Isabella launch; arc and speeds inferred from the SE/S/SW orientation hint and general southern-Sierra mountain-launch knowledge. The launch is south-facing (works best with wind FROM the SE-S-SW, ~135-225 deg met); SE and SW become cross/edge and the marginal arc extends slightly into E (~112) and W (~247). This is high-desert terrain above Lake Isabella reservoir (launch ~3383 ft MSL) and is known locally as a speed-flying/paragliding area (SpeedFly Sports operates here). Expect strong midday thermal cycles and valley/lake convergence; afternoons can over-develop with gusty thermic conditions and dust devils. Best window is typically morning or late-afternoon glass-off when wind is lighter and cleaner. HAZARDS: strong east or west wind produces lee-side rotor/turbulence off adjacent ridges; the Kern River valley funnels wind so velocities can build fast in the afternoon - watch for rapid increases and gust spreads. Treat any speed above ~18 mph base or ~22 mph gust as a no-go for paragliders. Likely an intermittent / P2-P3+ thermic mountain site - confirm current rules, access, and local guidance with SpeedFly Sports or the nearest USHPA chapter before flying.
