Sequoia in September: what the park service says
From September the weather in Sequoia usually starts cooling at night, the park service says, though days can stay warm and it can turn stormy fast after a hot spell. Through the fall, facilities cut their hours or close and ranger programs thin out, and Mineral King and Cedar Grove close once the snowy season comes. Light snow that melts quickly can begin in late October.
