Before you go
Østmarka (Lia) after rain
Østmarka: gneiss boulders in the forest, in Oslo, Norway. The nearest other areas here are Tokerud (8 km), Vesterøya (101 km) and Ula (105 km).
Is Østmarka dry today?
The answer at the top of this page comes from MET Norway's forecast and how fast gneiss dries, and it's updated through the day. Nobody checks the rock in person, so touch the holds before you climb.
How long does Østmarka take to dry after rain?
Østmarka is gneiss. 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 7 hours of dry weather, most of the forest about 12 hours, and shaded ones about 17 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 Østmarka when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
