Bouldering gyms near the forest, for a wet day.
Best time to climb at Merkenstein, month by month
Merkenstein: limestone boulders in the forest, in Lower Austria, Austria. The nearest other areas here are Blockheide Gmünd (122 km), Pohorje (164 km) and Moravský Kras (165 km).
The answer at the top of this page comes from the German weather service'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.
Merkenstein 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 forest 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.
Wet rock is slick, and pockets and cracks seep for days. If the holds feel greasy, come back later. In the Wienerwald biosphere reserve: stay on the paths.
