Lagos, on Nigeria's Atlantic coast at 6.5°N, is one of Africa's largest cities, with intense Bortle 8–9 light pollution across the sprawling metropolis. The humid tropical climate brings frequent cloud, with a long wet season from April to October. Near the equator, both celestial hemispheres are accessible through the year, and the bright Milky Way core passes high overhead in season. Genuinely dark skies require travelling well inland, away from the coastal megacity, where rural Bortle 4 conditions open up. The drier months from November to March offer the most reliable clear nights.
