Bouldering gyms near the forest, for a wet day.
Best time to climb at The Scalp, month by month
The Scalp: granite boulders in open country, in County Dublin, Ireland. The nearest other areas here are Glendalough (26 km), Portrane (31 km) and Cromlech Boulders (143 km).
The answer at the top of this page comes from the Met Office'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.
the Scalp 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 boulders 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.
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later.
