El Niño Signal Is Active Off Ecuador as December Warming Enters the Forecast

Ecuador’s El Niño signal remains active off the country’s coast, and ocean warming could intensify toward the end of 2026, according to El Universo on August 20, 2026. The report says the largest warming is projected for December, although the atmospheric response and its effects on rainfall still need to be evaluated.

The indicators being watched

The Ecuadorian El Niño Index, or Iefen, has remained active for approximately seven consecutive weeks. The condition is linked to sea-surface-temperature anomalies in both the central Pacific and the waters in front of Ecuador.

In the Niño 1+2 region, which covers the waters off Ecuador between the equator and 10 degrees south latitude, the anomaly reached up to 4°C in the latest week cited by the report. The average sea temperature there was around 25°C.

In the central equatorial Pacific, the average anomaly reached approximately 2.7°C, with temperatures close to 29°C.

The report says the water has cooled slightly compared with earlier months but remains above the values expected for this time of year. Projections from international institutions, including the U.S. National Oceanic and Atmospheric Administration, point to potentially strong or very strong conditions during the October–December quarter.

What this does not tell Cuenca residents yet

An active coastal ocean signal is not the same thing as a specific forecast for tomorrow in Cuenca. The fetched report does not give a Cuenca rainfall total, a local emergency order, or a city-specific timetable for impacts.

That distinction matters because a climate signal can be important without answering the immediate question of whether a particular neighborhood will see rain, heat, or disruption on a given day. The next useful information will come from updated monitoring of the ocean and atmosphere.

What this means for Cuenca expats

For residents planning travel, outdoor work, or property maintenance, treat the late-year period as a monitoring window rather than a confirmed disaster forecast. Keep an eye on updates from Ecuadorian weather and ocean-monitoring institutions as the October–December period approaches.

The strongest verified point today is the persistence of the signal: Iefen has been active for about seven weeks, and the waters off Ecuador remain warmer than expected. The source does not establish how those conditions will translate into Cuenca’s local weather.
