The elevation at the Monument is 4,000 feet (1,220 meters) and as a result, we experience comfortable summer temperatures (65-85 F, 18-29 C) and snowy winters. The climate of the region is strongly influenced by the ocean which contributes to over 50 inches of rain per year. Expect rainy weather during spring and fall at the Monument and bring your rain gear!
Visit NOAA for the latest weather updates.
If you plan on attending a cave tour, you should bring a warm sweater and sturdy shoes to dress for the 44 F (7 C) cave.
Winter Weather Driving Advisory
If you are traveling to Oregon Caves during October through April, be aware of the snow hazards predicted. Visit NOAA for more information, and call or email Oregon Caves regarding snow conditions. If you do drive up to the Monument or Preserve, it is recommended that you carry chains or have traction tires. Be aware that tours are seasonal and are not offered from late fall to mid-spring. However, Oregon Caves National Monument and Preserve is always open to visitors. Occasionally in winter, snow can temporarily close park roads until they are plowed.
