Northern Peru Coast

The northern coast of Peru, from Trujillo to Tumbes, transitions between two oceanographic regimes. South of Punta Falsa, the Humboldt Current dominates: cold upwelling, dense fog (garúa), and nutrient-rich cold water that supports world-class sardine and anchovy fisheries. North of Punta Falsa and increasingly toward Máncora and Tumbes, the Equatorial Countercurrent delivers warm water from the west, raising sea surface temperatures to 22–26°C and eliminating the fog. This makes the far north of Peru, in terms of water temperature and weather, feel more like Ecuador than Lima. The surfing at Huanchaco and the historic caballito de totora reed-boat tradition are as old as the Chan Chan adobe city nearby — surfing and fishing from reed boats on this coast predate European contact by at least 700 years. Further north, Máncora's point break delivers consistent rights year-round in the warm-water zone. Pacific semidiurnal tides with mean range 1.0 to 2.0 m depending on location.
