Lagos Ships Its Own Tide Gauges Because No One Else Will

LAGOS — When the Oceanic & Atmospheric Assembly's regional buoy fell silent in June, the lagoon districts did not wait for a repair budget. A volunteer network now reads eleven improvised tide staffs by hand at dawn and dusk, and the numbers it logs match the Assembly's last good record within two centimeters. "The ocean does not send us a notice before it comes up the street," said Folake Adebayo, a fishmonger in the Makoko waterfront who now records the morning mark. "So we read it ourselves." The Assembly, which monitors sea level against the +2.8°C baseline that has held for a fifth straight month, confirmed the citizen gauges are "consistent with our model" but cautioned that hand readings cannot replace calibrated instruments. For Adebayo, the point is not to replace anyone. It is to know, on the mornings the tide runs high under her stall, exactly how high — before the water tells her itself.
