Best time to climb at Grohman Narrows, month by month
Grohman Narrows after rain
Grohman Narrows: granite boulders in the forest, in British Columbia, Canada. The nearest other areas here are Frank Slide (213 km), White Buddha (236 km) and Big Choss (240 km).
Is Grohman Narrows dry today?
The answer at the top of this page comes from Environment Canada'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 Grohman Narrows take to dry after rain?
Grohman Narrows 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 Grohman Narrows when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
