weather

Plan an earlier finish, slower footing beneath leaves, warm stops, and current seasonal access.

Decide when storms, flooding, wind, heat, visibility, or ice make the original route or its backup unsuitable.

Read gusts against exposed terrain, prepare before leaving shelter, and turn back when balance or communication deteriorates.

Check differences in elevation, shade, trail surface, access, daylight, and the conditions on the return.

Separate insulation from weather protection and adjust layers before a climb leaves your clothing soaked with sweat.
