Milky Way & night sky
From Tower Hill Botanic Garden, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.2 hours on a moonless night), and the core peaks around 19° above the southern horizon. Our light-pollution model puts the sky at about Bortle 6 (bright suburban 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: 6 Bortle 6 — Bright suburban sky. The Milky Way is only visible near the zenith; the sky glows grey-orange in photos. Modeled zenith brightness ≈ 19.15 mag/arcsec². Aurora needs roughly Kp 5.5+ 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 51% average cloud cover) and May as the cloudiest (64%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
