The city of São Paulo recorded its highest traffic congestion levels for the year on Tuesday, October 10, due to persistent rain affecting the region since the start of the week. According to the Companhia de Engenharia de Tráfego (CET), by 7:30 AM, the city was experiencing 1,054 kilometers of traffic slowdown, surpassing a previous record of 1,053 kilometers set just days earlier. This increase in congestion highlights the severe impact of adverse weather conditions on urban traffic dynamics.

The rainy weather has contributed to a challenging commute for residents, as reported by the Centro de Gerenciamento de Emergências (CGE). The average temperature during the early hours was around 18.3°C, with forecasts indicating a day characterized by many clouds and intermittent rain. These conditions were expected to turn from light rain in the morning to moderate to heavy rainfall in the afternoon and early evening, further complicating the situation on the roads.

The implications of such extreme traffic congestion are significant for urban planning and emergency management in São Paulo. High congestion levels can lead to increased travel times, impacting not only daily commutes but also emergency services and public transportation efficiency. This situation underscores the need for enhanced infrastructure and traffic management strategies to mitigate the effects of extreme weather on urban transportation systems, particularly in major metropolises like São Paulo.
