. As fronts approach, they are forced upward by the peaks of the Olympic Range, causing them to drop their moisture in the form of rain or snowfall ( Orographic lift). As a result, the Olympics experience high precipitation, especially during the winter months. This climate supports an un-named glacier on its east side. During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer. In terms of favorable weather, the best months for viewing and climbing are July through September.
