Ideal speed

3–10 mph

Ceiling · Paragliding

Boulder's Wonderland Lake site (RMHPA) — four east-facing launches that fly best in east wind, with NE–SE all workable and south sometimes okay. Weak morning lift builds to strong midday thermals (advanced only mid-day), then a gentler evening cycle as shade comes in. North wind is dangerous — rotor can shut the site down — and a westerly shift risks going over the back into the Rockies' lee. P2/H2 minimum with a high-altitude endorsement (launch ~6,250 ft).
