19th World Paragliding Championships Castelo Weather Forecast 8th Sep

Summary "Instability remains, low clouds and rain to the North and East"

Unstable conditions remain. 

Early broken clouds, with a shower above Castelo is expected at 10.00h.

Afterwards the rain clouds will expand to the North and East areas, where showers will be active all day.

Humidity similar, Dewpoint similar (17 C) will create Cu at 1000m, maybe up to 1500 to the NW of Castelo area.

Boundary Layer Humidity is less than yesterday by 10% (70-80%). It will remain higher to the North and East.

Weak lift (<1,5m/s) reaching from 750-1000m at 15.00

East from the take off 90% Cloud coverage and to the SW 30%.

It seems that there will be a lower humidity circle around Castelo, but conditions will be weak and thermal cycles very long, with not well organised thermals and energy flow will be very low.

Another day of patience, the main weather issues will be to the east, but tommorrow seems to be a better day with thermals +4 to 1900m.
