Milky Way & night sky
From George L. Luthy Memorial Botanical Garden, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.7 hours on a moonless night), and the core peaks around 20° above the southern horizon. Our light-pollution model puts the sky at about Bortle 8 (city sky), so expect visible sky glow; drive away from towns for better results.
