Best time to climb at Hurissalo, month by month
Hurissalo after rain
Hurissalo: granite boulders in the forest, in South Savo, Finland. The nearest other areas here are Keljonkangas (136 km), Piilolampi (196 km) and Sipoo (196 km).
Is Hurissalo dry today?
The answer at the top of this page comes from MET Norway's forecast and how fast granite dries, and it's updated through the day. Nobody checks the rock in person, so touch the holds before you climb.
How long does Hurissalo take to dry after rain?
Hurissalo is granite. 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 Hurissalo when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
