Olympic National Park

With its incredible range of precipitation and elevation, diversity is the hallmark of Olympic National Park. Encompassing nearly a million acres, the park protects a vast wilderness, thousands of years of human history, and several distinctly different ecosystems, including glacier-capped mountains, old-growth temperate rain forests, and over 70 miles of wild coastline. Come explore!

Weather & conditions

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, snowfall can be heavy in the mountains. It is common for different weather conditions to exist within the park at the same time. At any time of year, visitors should come prepared for a variety of conditions.

What this latitude gives you

From 47.8° north, anything above declination +42.2° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -42.2° never clears the horizon at all.

Full astronomical darkness survives the summer here, but the window is narrow around the solstice. From late August the nights lengthen quickly.

We do not hold a measured Bortle class for this site, so treat the sky as unknown until you have taken a reading of your own.
