Sanger, CA — light pollution & stargazing

California · Very poor — city glow · population 24,950

Sanger, California has a light-pollution rating of about Bortle 8 — a city sky (very poor — city glow) — measured from VIIRS 2024 satellite night-lights at 40 nW/cm²/sr at the town center. The sky is bright enough to read by. Only the Moon, the planets, and the few brightest stars and clusters are visible — the constellations lose most of their fainter stars. The nearest genuinely darker skies are around Parlier, CA (about 7 mi away, Bortle 7). 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.
