In Brazil
rain · fire · riversEl Niño disturbs the atmospheric circulation over South America. The classic pattern: a drier North and Northeast (the Amazon and the semi-arid region lose rain, and fire finds dry forest), a wetter South (floods in Rio Grande do Sul and Paraná, especially in spring) and a hotter Southeast and Center-West. No year matches the pattern exactly, and the list below shows what is actually happening.
Accumulated rainfall relative to normal
Sum of daily rainfall (Open-Meteo: ERA5 and operational analyses) over the chosen window, compared with the 1991–2020 normal for the same period at the same point.

Cumulative fire hotspots in the year
INPE reference satellite (AQUA, afternoon pass) — the only series comparable across years. Gray: 2003–2025. Highlighted: 2024 (recent record, after the 2023–24 El Niño), 2015 and the current year.
02Rivers
Negro River at Manaus
Negro River stage at the Port of Manaus (ANA telemetry). Extreme Amazon droughts come with strong El Niños.
Guaíba Lake at Porto Alegre
Guaíba level at Cais Mauá (ANA telemetry). Southern Brazil tends to get above-normal rain in El Niño years. The telemetry went down during the historic May 2024 flood (peak above 5.3 m), which is missing here.
