The Night Sky in Washington

This year's meteor showers, moon phases, and the darkest places to watch from in Washington.

Data updated: August 2026Sources & method · Corrections

The best stargazing in Washington comes on clear, moonless nights, and January, November and December give you the most of them to work with — about 15.5 hours of darkness at the December peak, computed from Washington's own sun times. Below: this year's meteor-shower peaks and how bright the moon will be for each, a month-by-month new- and full-moon calendar, and the darkest places to watch from.

Washington's stargazing conditions vary sharply from west to east: the heavily populated, cloud-prone Puget Sound corridor around Seattle and Tacoma carries significant light pollution and a marine layer that keeps skies overcast for much of the year, while the drier interior east of the Cascade crest sees far more clear nights and much less artificial light. The best viewing tends to fall in late summer and early fall, after wildfire smoke has cleared but before the winter rains return. Elevation helps as well, since high viewpoints and mountain passes often rise above valley haze and low cloud decks. On a clear night away from the Interstate 5 corridor, the state's public lands can offer noticeably dark skies within a few hours' drive of any major city.

Dark-sky places in Washington

  • North Cascades National Park — One of the least-visited national parks in the country, with vast roadless wilderness and almost no artificial light nearby; campgrounds and trailheads along the North Cascades Highway offer some of the darkest skies in the state on clear nights.
  • Olympic National Park — The park's remote ocean beaches and forested valleys sit far from any city, and high viewpoints such as Hurricane Ridge often rise above the coastal cloud layer for extra clarity on a clear night.
  • Colville National Forest — Washington's northeasternmost national forest covers a large, thinly populated stretch of the state near the Canadian border, with little nearby development to wash out the sky.
  • Rural areas east of the Cascades — The dry, open country from the Okanogan highlands to the Blue Mountains has a fraction of the population density of western Washington; state parks and forest roads throughout this region make good impromptu viewing spots away from town lights.

Ranger programs, star parties and opening hours change season to season — check with the site before you drive out.
