What we look for here
  • Wind directionNNE (20°) → ENE (70°)
  • Ideal speed6–15 mph
  • Upper limits≤ 18 mph base · gusts ≤ 20

Paragliding-only high-mountain launch (~7592 ft MSL) above Honey Lake / Janesville, NE Sierra. BHGC site guide confirms the launch but gives no explicit wind numbers; arc inferred from paraglidingEarth orientation (N, NE, E). Launch works in wind FROM the N-through-E quadrant, ideal NE (~045). Wind speeds inferred from general mountain-PG practice (light morning/evening glass-off conditions favored). HAZARDS: big ~3400 ft vertical to the valley LZ (5:1 glide to Janesville Park LZ at ~4200 ft, 40.2989/-120.5227); strong thermal/valley convergence and possible overdevelopment on hot afternoons; lee-side rotor and venturi if a westerly/SW gradient builds over the Sierra crest (high desert behind) — avoid W/SW component. BEST TIME: morning or smooth evening glass-off; midday can get strong/turbulent in summer. ACCESS: road to launch is behind a LOCKED GATE — must call the manned firewatch at 530-616-0529 for access. Move glider into the park for teardown; do not break down in the field. Numbers are estimates — verify with BHGC and locals before flying.
