Olympic National Park has mild winters and pleasant summers. The weather can vary greatly depending on whether you are on a beach on the ocean, wandering in a rainforest, or hiking in high elevations in the Olympic Mountains.
The Olympic Mountains Experiment (OLYMPEX) measures precipitation and help NASA fine-tune new weather satellites. Mules get the equipment into remote areas.
73 miles of coastline turn into a wave crashing show in the winter. From Nov through Feb, storms coming in from the Pacific have wind gusts up to 60 mph.
