Rio de Janeiro experienced a period of weather instability characterized by rainy days that caused flooding and fallen trees. 

By mid-September, a high-pressure system brought a temporary break from the rain, with temperatures rising to 29°C and cloudy to partially cloudy skies. While wind gusts were a concern during this period, the dry air mass allowed for warmer temperatures. 

By late September, the weather showed signs of stability following a sunny period, though forecasts indicated increasing cloud cover and a 55% probability of light, isolated rain during the night.
