• São Paulo reached 35.9°C on December 25, the highest December temperature on record in the city, while Rio de Janeiro hit roughly 41°C and activated heat Protocol level 3.
• Rio state health officials classified the capital at severe risk and urged public hydration points and cooling shelters, and the city logged 973 heat‑related emergency visits between December 23 and 24.
• São Paulo’s state government asked residents to cut water consumption after demand spiked and reservoirs came under pressure during the heat.
