Peruvian waters continue to show sea surface temperature (SST) anomalies, with positive deviations increasing slightly in both intensity and coverage. Off the coast of Paita, a warm water mass persists with temperatures 2°C above average for mid-July.
In the ENSO 1+2 region (northern Peru and Ecuador), SST anomalies remain stable at +0.4°C, the same as last week. The central Pacific (ENSO 3.4) continues at +0.0°C.
According to NOAA’s latest bulletin, the Oceanic Niño Index (ONI) for April–May–June stands at -0.1, unchanged from the previous period. These indicators collectively suggest that the Pacific remains in a neutral ENSO phase, with no immediate threat of extreme oceanic events.
