Top bouldering picks for September
Fontainebleau
Forest sandstone boulders south of Paris. September is the pick, and the spring-to-summer run from April is the other steady window between wet winters.

Cederberg sandstone that lives on cold, dry air. September and October are the window: the winter cold-front rain has closed but afternoons are still cool enough for good friction.

Forest granite boulders beneath the Chief. Once the Pacific wet season closes, May to September is the plateau, peaking in July and August.
