Sea Rim State Park — a state park in Jefferson County, Texas — is a popular subject for landscape photographers. The nearest town is Port Arthur, about 22 km (14 mi) away (Sea Rim State Park lies SSW of town).
Sea Rim State Park is a 4,141-acre (1,676 ha) state park in southeast Texas. The park is located on the Gulf of Mexico in southern Jefferson County, south of Port Arthur and just west of Sabine Pass. The park was closed for several years due to extensive damage from Hurricanes Rita (2005) and Ike (2008). The park reopened in 2010.From the Wikipedia article “Sea Rim State Park”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
State parks often protect a signature feature — a gorge, lake or overlook — that is best in early morning before visitors and harsh light arrive.

Milky Way & night sky
From Sea Rim State Park, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.7 hours on a moonless night), and the core peaks around 31° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.36 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 38% average cloud cover) and February as the cloudiest (64%). August is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
