High

Wind, rain and daily score: 08:00–18:00 local time.

Experimental wind estimate: Shelter at individual holds and belays is unresolved. Strong gusts may differ substantially; summit-station validation does not establish crag-level accuracy.

Wind: This climbing signal uses wind on the face and at exposed belays. Open ground above is not included because the represented climbing normally finishes at lower-offs. The exact amount of shelter at the cliff is uncertain. A precomputed terrain-flow profile refines how the face shelter changes with wind direction.

Some sectors may be usable, but shaded, polished or seeping sections could remain poor.

Wet rock or seepage-prone sections are a concern; choose another crag or wait for direct observations.

Drying is plausible, but confirm the rock at the crag before committing.

The exact amount of shelter at the cliff is uncertain. A precomputed terrain-flow profile refines how the face shelter changes with wind direction.

The broad weather signal favours dry rock; local seepage and route-level dampness remain possible.
