Rio Hits 41.4°C as Heat Protocol Stays in Force and Emergency Actions Ramp Up

Overview

• Alerta Rio reported 41.4°C in Santa Cruz on Monday, the highest reading of the week in the city, with Marambaia reaching 40°C earlier in the day.
• Rio remains at Calor 3 in the municipal Heat Protocol, with authorities cautioning that relative humidity may drop near 20% to 30%.
• Health services installed external hydration points at all 27 UPAs and reinforced Samu 192 with rapid-response units, while beach hydration stations saw repeated refills of 150‑liter coolers.
• Crowds leaving the beaches produced long queues at Ipanema’s General Osório metro entrance and ride‑hailing fares surged, including R$85 from Ipanema to Lapa and R$70 from Copacabana.
• Forecasts keep daytime heat elevated through the week with increasing chances of afternoon and evening showers, as southern states such as Paraná remain under storm alerts following a recent extratropical cyclone.
