Flymaster Open 2025 Krusevo June 11th Weather Forecast

 

Summary of the Day forecast

The North winds drop by 5kph, making the day more flyable in this regard. 

Barometer drops a little making smoother the inversion which will be higher than yesterday at 2000m (yesterday 1650m).

Humidity will decrease by 5%, meaning that thermals will be a little stronger especially close to the ground, and cloudbase will be higher.

Temperature contrast at 14 C, meaning better thermal triggering close to the ground.

Thermals will be easier to find close to the ground, half a meter stronger, and more organized comparing to yesterday due to the smooth east wind component.

Day will start with few Cu clouds to the west at 11.30-12.00.

At 13.00 we will have the first valley Cu, that will have spreadout. The peak of conditions will be at 14.00 but Spread out may be a challenge as the very strong inversion at 3500 will force clouds to expand horizontally.

In general it will be a smoother day, will similar thermal power to yesterday, with more organized thermals and smoother close to the ground and close to the inversion, and clouds may create fast and have spreadout fast too.
