Weather and wind conditions such that a glider - either a hang glider, paraglider, sailplane, or soaring bird - can soar, i.e. maintain or gain altitude without aid of an engine or other power source, including flapping.  The soaring may be due to making use of thermals or ridge lift.  Soarable conditions are a subset of flyable conditions.
