Can I climb todayToday: Maybe. Only the sunniest, windiest boulders from 14:00, if any. Check for seepage and wet holds first.

Best time to climb at Glees, month by month
Glees after rain
Glees: basalt boulders in the forest, in Rhineland-Palatinate, Germany. The nearest other areas here are Berdorf (96 km), Rocher de Nasproué (97 km) and Rochers de Stoumont (105 km).
Is Glees dry today?
The answer at the top of this page comes from the German weather service's forecast and how fast basalt dries, and it's updated through the day. Nobody checks the rock in person, so touch the holds before you climb.
How long does Glees take to dry after rain?
Glees is basalt. It sheds rain quickly, though cracks, pockets and tufas can seep for days after heavy rain. 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 8 hours of dry weather, most of the forest about 14 hours, and shaded ones about 19 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 Glees when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
