The European Centre for Medium-Range Weather Forecasts (ECMWF) issued an updated seasonal forecast for Argentina covering September, October, and November 2026. [^1]

Celeste Saulo, secretary general of the World Meteorological Organization (WMO) and former director of the Servicio Meteorológico Nacional, stated that El Niño will modulate seasonal thermal patterns to produce a spring with higher precipitation in the Littoral and eastern fringe. [^2]

Marina Fernández, a specialist at the ECMWF, stated that the most consistent moisture signal during the quarter is concentrated in northeastern Argentina, including Corrientes, Misiones, and parts of Chaco and Formosa. [^3]

The ECMWF models project that the northeastern region will record the most persistent wet signal of the quarter, with precipitation amounts exceeding normal values. [^4]

Marina Fernández, a specialist at the ECMWF, stated that the northeastern Argentine provinces of Corrientes, Misiones, Chaco, and Formosa will experience notable increases in humidity and above-normal precipitation due to the warm phase of El Niño. [^5]

The strengthening El Niño phenomenon in the equatorial Pacific is expected to cause significant changes in rainfall and temperature patterns across Argentina in 2026. [^6]

The uneven distribution of rainfall is considered crucial for planning the 2026/2027 agricultural cycle, especially in the Pampas region. [^7]
