Paragliding World Cup Krusevo, Weather Forecast 25th of July 2025


Summary of the Day forecast - "Strong Upper N wind brings uncertainty"

A similar day in the valley to yesterday, very hot but enough triggering after 14.00h in flat land and temperatures up to 39 C

Temperature contrast 25-37 (+12 C) less than yesterday. 

Same low humidity <20% and increased humidity at 3.000m, expected more cloud visible signs.

Good convergence line across Krusevo mountains to Bitola

Convergence clouds at both Krusevo and Prilep ridges

Similat thermals at all levels maybe a little weaker (less 0,5m/s)

A slight increase of barometer pressure, with a more strong inversion at 2100 with some turbulence and broken thermals at this level as NW wind will be above this altitude.

Very high cloudbase is predicted (4000m) and thermals theoretically reaching more than 3800m.

Actually, surface gusts that can reach 30kph and higher winds that can break thermals at 2100-2200m may increase turbulence and be a challenge for paragliders.

It seems possible that North winds of 25kph will enter the area above 2100m at 15:00h and be critical for the task algorithm.
