Shasta Lake, CA — light pollution & stargazing

California · Poor — bright suburban · population 10,159

Shasta Lake, California has a light-pollution rating of about Bortle 6 — a bright suburban sky (poor — bright suburban) — measured from VIIRS 2024 satellite night-lights at 11 nW/cm²/sr at the town center. The Milky Way is effectively invisible and the sky has a grayish glow near the horizon. Bright star clusters and the Moon and planets are the reliable targets; galaxies need a telescope. The nearest genuinely darker skies are around Magalia, CA (about 73 mi away, Bortle 4). Tonight's Moon phase, cloud cover, and aurora odds load live below, computed in your browser.

How to read this rating

The darkness rating is measured from VIIRS satellite night-lights at the town center and is a proxy for planning, not a survey-grade sky-brightness measurement — and the darkest skies are usually a short drive out of any town. Tonight's Moon, cloud, and aurora figures are live third-party forecasts that can change. See the methodology for sources and limits.
