Like everything else about Olympic, the weather is extremely variable, from season to season and place to place.  Visitors should come prepared for a wide range of conditions.  Rain gear and layered clothing are essential.

Overall, the Olympic Peninsula has a moderate marine climate with pleasant summers and mild, wet winters.

Summers tend to be fair and warm, with high temperatures between 65 and 75 degrees F. July, August and September are the driest months, with heavier precipitation during the rest of the year.

While winters are mild at lower elevation, with temperatures in the 30's and 40's, snowfall can be heavy in the mountains, with accumulations of up to 10 feet common.
