Can I climb todayTomorrow: Maybe. Only the sunniest, windiest boulders, if any. Check the holds and any seepage first.

Best time to climb at Rochers de Stoumont, month by month
Rochers de Stoumont after rain
Rochers de Stoumont: boulders in the forest, in Liège, Belgium. The nearest other areas here are Rocher de Nasproué (23 km), Freÿr (67 km) and Berdorf (78 km).
Is Rochers de Stoumont dry today?
The answer at the top of this page comes from the German weather service's forecast and how fast the rock dries, and it's updated through the day. Nobody checks the rock in person, so touch the holds before you climb.
How long does Rochers de Stoumont take to dry after rain?
We don't have Stoumont's rock type on record, so the model dries it slower than granite or limestone, to err on the wet side. These times are the model's estimates, tuned on Fontainebleau sandstone and not checked here. After a proper soaking (2 mm of rain or more), sunny, windy boulders need about 11 hours of dry weather, most of the forest about 18 hours, and shaded ones about 25 hours. A light shower needs less. Wind, sun and dry air shorten the wait, and above about 92% humidity the model won't call the rock dry.
Can you climb at Rochers de Stoumont when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
