In the tug-of-war for Ecuador’s coastline, the Humboldt Current and El Niño are the lead players. But as we start 2026, a third character—La Niña—is currently holding the rope.
Here is the breakdown of why this battle matters for your wallet and your weekend plans, along with the latest forecast for the year ahead.
1. The Science: Cold vs. Warm
- The Humboldt Current (The Constant): This massive “conveyor belt” flows north from the Antarctic, bringing cold, nutrient-rich water. It creates upwelling, where deep-sea nutrients rise to the surface, feeding the plankton that sustain Ecuador’s massive fish stocks.
- El Niño (The Intruder): When trade winds weaken, warm water from the western Pacific “sloshes” back toward South America. This warm layer acts like a lid, stopping the nutrient upwelling and essentially “shutting down” the ocean’s engine.
- La Niña (The Current State): The opposite of El Niño, where trade winds are extra strong, pushing even more cold water to the surface.
2. Why This Is Important
For someone living in Ecuador, these currents aren’t just “weather”—they are economic and social drivers:
- The Price of Dinner: During Humboldt/La Niña cycles, fish like albacora (tuna) and camotillo are plentiful and cheaper. During El Niño, they disappear or dive deep, making your market run much more expensive.
- Infrastructure: El Niño isn’t just rain; it’s a structural threat. Historically, strong El Niños (like 1982-83 and 1997-98) have wiped out 15% of Ecuador’s GDP by destroying coastal roads and bridges.
- Energy: Ecuador’s hydropower depends on specific rain patterns. While El Niño brings floods to the coast, it can sometimes cause droughts in the Amazon-basin highlands where the big dams are, leading to the power cuts we saw in 2024/2025.
3. Current Situation: January 2026
We are currently in a La Niña Advisory.
- The Ocean: Waters off the coast are still cooler than average (around $-0.7$°C to $-0.9$°C).
- The Land: We are seeing typical seasonal rains, but without the extreme flooding associated with El Niño. However, the cooling effect has contributed to drier conditions in some highland agricultural zones.
4. What to Watch For (The 2026 Forecast)
- Short Term (Feb–May 2026): Transition to Neutral. Forecasters give a 75% chance that the current La Niña will fade by March. Expect the ocean to reach “room temperature”—neither exceptionally cold nor hot.
- The “El Niño Watch” (Late 2026): Several international models (NOAA and ECMWF) are detecting a “warm pool” of water moving deep below the surface in the western Pacific.
- The Red Flag: If we see a rapid shift toward warming in June/July, we could be looking at a significant El Niño by late 2026. This would mean a very hot, very wet end to the year for the coast.
Summary / Resumen
English: As of January 2026, Ecuador is moving out of a weak La Niña into a “Neutral” state. This transition means more predictable weather for the next few months. However, scientists are tracking subsurface warming that suggests a potential return of El Niño in the second half of 2026. Watch for rising sea temperatures in July as a sign of heavy rains to come.
Español: A partir de enero de 2026, Ecuador está saliendo de una fase débil de La Niña hacia un estado “Neutral”. Esta transición significa un clima más predecible para los próximos meses. Sin embargo, los científicos están rastreando un calentamiento submarino que sugiere un posible regreso de El Niño en la segunda mitad de 2026. Esté atento al aumento de las temperaturas del mar en julio como señal de fuertes lluvias por venir.
