Travelers planning journeys in El Niño affected areas (e. g. Latin America) shall know that this year a very strong El Niño is expected, beginning late summer / early autumn. Of course this would influence also wider regions.
"El Niño (La Niña) is a climate phenomenon in the equatorial Pacific Ocean that occurs when sea surface temperature (SST) anomalies in the Niño 3.4 region remain above (below) the threshold of +0.5°C (-0.5°C) for five consecutive overlapping 3-month periods, after adjusting for overall tropical ocean temperature patterns. (source)"
Latest updates of forecast models for region 3.4 show with > 3°C a very significant expected value above the +0.5°C (source). The average expected value is now over the measured values from strong El Niño season 2015 / 2016 with average +2.7°C.
"As of mid-April 2026, the equatorial Pacific is in an ENSO-neutral state but rapidly transitioning toward El Niño. The latest CCSR/IRI ENSO plume forecast gives a 70% chance of El Niño developing in April–June 2026 versus 30% for continued neutrality, with El Niño remaining dominant through the rest of 2026 at high probabilities of 88–94%.
