Before you go
Marble Valley after rain
Marble Valley: boulders in open country, in Castelo Branco, Portugal. The nearest other areas here are Los Barruecos (106 km), Valcorchero (144 km) and Sintra (177 km).
Is Marble Valley dry today?
The answer at the top of this page comes from ECMWF'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 Marble Valley take to dry after rain?
We don't have Marble Valley'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 boulders 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 Marble Valley when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
