Milky Way & night sky
From Leaning Pine Arboretum, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.8 hours on a moonless night), and the core peaks around 26° above the southern horizon. Our light-pollution model puts the sky at about Bortle 7 (suburban / urban transition), so expect visible sky glow; drive away from towns for better results.

Estimated sky darkness: 7 Bortle 7 — Suburban / urban transition. The whole sky has a grey-white glow; the Milky Way is invisible to the eye. Modeled zenith brightness ≈ 18.8 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 18% average cloud cover) and December as the cloudiest (48%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.
