The Best Times for Stargazing in Calexico

Expert Tips for Calexico Observers

When observing from Wilcox Community Center, try to position yourself facing away from the nearest major light dome. For Calexico residents, this usually means looking toward the rural horizons of CA to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Cottonwood Campground (75.0 miles away) remains the benchmark for regional sky quality.

Regional Perspective: Observers in Calexico often prefer their local clearings over Holtville for spontaneous stargazing, thanks to a shorter commute into the dark zones.
