Paragliding World Cup Sopot Weather Forecast 11 Sep

  

Summary of the Day

The frontal activitiy is very close in the Balkans. This increases higher level humidity, involves west winds above the inversion and develops high clouds in the area, mainly across the ridges of Sopot. 

More instability at a higher level above 2000m, and in general a stronger thermal day comparing to the previous one.

cloud bases above 3300m are expected after 15.00, with top of clouds at 5000m.
