Milky Way & night sky
From Hook Mountain State Park, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 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.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 8 Bortle 8 — City sky. Only bright constellations are visible; the sky glows orange or white. Modeled zenith brightness ≈ 18.35 mag/arcsec². Aurora needs roughly Kp 6.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 50% average cloud cover) and December as the cloudiest (65%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
