Before you go
Gallt yr Ogof after rain
Gallt yr Ogof: boulders in open country, in Conwy, United Kingdom. The nearest other areas here are Cromlech Boulders (7 km), Parisella's Cave (25 km) and Pantymwyn (50 km).
Is Gallt yr Ogof dry today?
The answer at the top of this page comes from the Met Office'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 Gallt yr Ogof take to dry after rain?
We don't have Gallt yr Ogof'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 Gallt yr Ogof when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
