No wind is still a perfect scenario for paragliding as it allows for better thermals and sometimes even better thermic flights.  As far as variable weather during flight, it does not affect our flight that much as we will maintain constant airspeed regardless of the meteorological wind experienced.  There are however some cases where inclement weather could affect the pilot's decision about aborting his takeoff.  Typically, this includes gust fronts, wind squalls, increasing wind speed, or a change in wind direction. All of these have visible signs to experienced pilots and can be avoided altogether In the worst case in no wind conditions, we will simply glide steadily until we land safely.
