The Best Times for Stargazing in Clearlake
While Winter offers the most consistent clear nights for Clearlake, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Winter months, you can often begin deep-sky imaging as early as 7 PM.
Expert Tips for Clearlake Observers
When observing from Foxboro Park, try to position yourself facing away from the nearest major light dome. For Clearlake 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 4 at Buckhorn Group Camp (60.6 miles away) remains the benchmark for regional sky quality.
