The Best Times for Stargazing in San Luis
Observation in San Luis is most rewarding during the Summer months. During this time, the colder air masses over the Southwest region often result in significantly higher transparency, allowing you to see objects like the Andromeda Galaxy or Orion Nebula with much more definition.
Expert Tips for San Luis Observers
Thermal equilibrium is key. Since San Luis temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Wilcox Community Center. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Pozo Nuevo Road (105.2 miles away) remains the benchmark for regional sky quality.

The scientific findings at Pozo Nuevo Road provide San Luis residents with the most reliable data on regional atmospheric stability.
"Skies cleared out nicely after earlier cloudiness. An excellent location with a view to the SW section of border wall and the Quitoboquito area. Sonoyta to SE was still bright with scattered light sources to the SW. Sonoyta 25° wide and 25° high. Incredible zodiacal light in the west with Venus and Jupiter setting. Zodiacal light stretched up into Pleiades at 70° high. Winter Milky Way was detailed all the way down to NW horizon. PHX light was visible behind the hills to the NE."
