Flymaster Open Krusevo 8 July 2025 Soaring Forecast

Summary

 The day will start later than yesterday but will evolve faster with clouds. Some Cu with high tops above 5000m will appear from the west and North, later in the afternoon also in the east. The 5500m inversion will block the creation of Cb clouds, but we may have horizontal overdevelopment in the west, north and east that will create some shade in the valley. 

Thermals will start 30min later than the previous day, but will be with less power around 3-4m/s between 1000 and 2700m at 16.00h at peak.

The sky will gradually close from the north to the south, with nice Cu cloud streets flyable at the end to the south to bitola goal while potential showers will apear in the close west and north.

The lower airmass and winds will be similar to the previous day (East<10kph) however higher winds will increase from the North West and above an inversion of 1800m.

Potential Shadow to the take off from the west due to the overdevelopment at 16.00h
