Bouldering gyms near the forest, for a wet day.
Buthiers: sandstone boulders in the forest, in Ile-de-France, France. The nearest other areas on this site are Fontainebleau (18 km) and Montagne de Beaune (225 km).
The answer at the top of this page says: yes means the rock should be dry, maybe means only the fastest-drying spots, and no means it's too wet. It comes from Météo-France's forecast and how fast sandstone dries, and it's updated through the day. Nobody checks the rock in person, so touch the holds before you climb.
Buthiers is sandstone, which soaks up rain and stays weak inside for a while after the surface looks dry. These times are the model's estimates, not measured here. After a proper soaking (2 mm of rain or more), sunny, windy boulders need about 18 hours of dry weather, most of the forest about 30 hours, and shaded ones about 42 hours. A light shower needs less time. A breeze shortens the wait, and above about 92% humidity the model won't call the rock dry.
Wet sandstone breaks. If a hold feels cool or damp, leave it for another day.
