Big Bend in October: what the park service says

October is when Big Bend's main season opens: the park service puts its primary visitor season at October through April. The overnight squeeze that defines winter here has not fully set in yet, since the park says the Chisos Mountains Lodge and every developed campground fill every night from November on. That makes October one of the easier months to land a site, but there are still no first-come campgrounds, so reserve on recreation.gov (up to six months out) before you drive in.
