Why

Even the best window is held back by rain and humid air (95% humidity).

What shapes this crag

Sun: On the face 15:00 to 18:00, when it shines.
Sea: Comes from behind the face, counted at 40%: 1.1 m at the wall.
Tide: Grip pulls the rock temperature harder towards the sea's, and counts spray from a 2 m sea rather than 2.5 m.
Seepage: None noted.
Birds: No information. Grip does not know whether birds nest here.

Grip is the blend of the three models. The points column shows the Met Office figures (the next model's where it does not reach), factors at zero left out. Wet risk is how many models have the rock wet, foggy or raining.
