Milky Way & night sky
From Border Field State Park, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.3 hours on a moonless night), and the core peaks around 29° 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.

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 ≈ 19.1 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show January as the clearest month (about 50% average cloud cover) and June as the cloudiest (81%). September is the warmest month and February the coldest, which matters for gear, snow access and how long batteries last at night.
