Bioluminescent Bay Glow at Dark Portuguese Shore

Midsummer starlight reflects off a dark Atlantic shoreline where the water pulses with faint, electric blue bioluminescence. The tide pulls gently against wet sand, leaving trails of glowing particles that shift with every small ripple. A thin layer of sea haze softens the horizon line, blurring the boundary between the deep indigo sky and the darker water. The glow illuminates the texture of the wet pebbles and the frothy edges of receding waves. Shadows stretch long across the beach, showing the quiet stillness of the pre-dawn hours. The light creates a soft, cool rim along the water's edge, fading into the surrounding darkness.
