Niagara Glen after rain
Niagara Glen: limestone boulders along a river, in Ontario, Canada.
Is Niagara Glen dry today?
The answer at the top of this page comes from Environment Canada's forecast and how fast limestone dries, and it's updated through the day. Nobody checks the rock in person, so touch the holds before you climb.
How long does Niagara Glen take to dry after rain?
Niagara Glen is limestone. 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 8 hours of dry weather, most of the boulders about 14 hours, and shaded ones about 19 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 Niagara Glen when the rock is wet?
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later. Access and parking are through Niagara Parks.
