Flymaster Open 2026 Weather Forecast 17th July

 

Soaring Weather Forecast

General Synopsis

Switching back to normal conditions.

After yesterday's rain, the valley is going to release a lot of moisture, causing morning clouds that will reach up to 2200m. As the ground dries, the cloud base will begin to rise higher, reaching 2700m at 13:00 and 3000m at 15:00.

Gradually, the cloud tops will develop through cycles and will eventually grow about 1000m  from their base to tops.

We expect overdevelopment from the west, which could bring 60% cloud coverage and shade in the valley after 16:30 in the Bitola area, while ieast of Krusevo cloud coverage will be at 20%. Clouds will also accumulate south of Prilep.

The day will continue to evolve until 17:00, when increased shading will degrade the thermal activity.

Higher up, the wind will be from NW around 22-32 kph above 2200m, while below the inversion at 1900m, it will be from the East at 10 kph.

Thermals will average around 3 m/s but will work in long cycles.
