Cave Junction Oregon Weather Guide

Cave Junction sits in the Illinois Valley at 1,319 feet, surrounded by the Siskiyou Mountains and Klamath National Forest. The narrow valley between mountain ridges creates weather quite different from the Rogue Valley — cooler summers, more precipitation, and a longer winter. Oregon Caves, just 20 miles away at 4,000 feet, can receive significant snowfall while the valley floor sees only rain.
