Overview
- The Navy's Dirección de Hidrografía y Navegación (DHN) has an alert in force through June 11 that forecasts anomalous waves growing in intensity and peaking around June 7–8.
- The Dirección General de Capitanías y Guardacostas (Dicapi) ordered the temporary closure of dozens of ports on the northern and central coast, with an official count of 46 closures while several outlets report higher totals.
- Senamhi has issued an orange alert for extreme coastal heat from June 5–8 with daytime highs up to 35°C, elevated UV levels and stronger winds that can raise short-term risks for coastal communities and marine operations.
- On-the-ground impacts already include rocks, sand and debris deposited on Callao's Costanera, suspension of artisanal fishing, and port and transport disruptions that complicate logistics during the electoral weekend.
- ENFEN confirmed a moderate El Niño Costero that has warmed near-shore waters and could sustain coastal anomalies into late 2026 or early 2027, so authorities urge securing vessels ashore, suspending maritime activity and following official Dicapi/DHN/COEN updates.
