(left) Monthly sea surface temperatures compared to average in the key Atlantic Niño/Niña monitoring region between January 1982 and July 2024 (with any long-term warming signal removed). The 2024 Atlantic Niño was the strongest (highest red bar) since 1982. (right) Temperatures in the eastern equatorial Atlantic were just shy of the Niña threshold in July 2024.
