Before you go
Lorimer Park after rain
Lorimer Park: sandstone boulders in the forest, in Pennsylvania, United States. The nearest other areas here are Haycock Mountain (47 km), Governor Stable (138 km) and Mocanaqua (147 km).
Is Lorimer Park dry today?
The answer at the top of this page comes from NOAA's forecast and how fast sandstone dries, and it's updated through the day. Nobody checks the rock in person, so touch the holds before you climb.
How long does Lorimer Park take to dry after rain?
Lorimer Park is sandstone, which soaks up rain and stays weak inside for a while after the surface looks dry. 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 18 hours of dry weather, most of the forest about 30 hours, and shaded ones about 42 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 Lorimer Park when the rock is wet?
Wet sandstone breaks. If a hold feels cool or damp, leave it for another day.
