Weather

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.

Did You Know?

Debugged-DYK

Computer bugs, slang for something gone wrong in a program, are actually named for a real insect. In 1947, technicians working for computer scientist Grace Hopper found a moth inside her computer. The trapped moth was making the machine malfunction. Once removed, they reported that the computer was “debugged”. They taped it onto her notes with a little joke that is now part of our everyday language.
