As autumn officially begins in Brazil on Friday at 11:45 AM, the first day still bears traces of summer’s rain showers in the metropolitan region of São Paulo. The CGE (Center for Emergency Climate Management) indicates that Friday will start off with cloudy skies and light rain, but as the day progresses, sunshine will emerge amidst the clouds, leading to a rise in temperatures. Milder temperatures are expected, fluctuating between a minimum of 19°C and a maximum that can reach 27°C.

By late afternoon, cloudy conditions are anticipated to return due to a sea breeze, bringing potential for quick rain showers in some areas of the city. This weather might impact attendees of the Lollapalooza festival at the Interlagos racetrack, who will need to prepare for the intermittent rainfall on Friday. However, by the weekend, the weather is expected to clear up significantly, with strong sunshine and heat dominating the experienced conditions.

This change in weather aligns closely with the previous day’s conditions, suggesting that while the official commencement of autumn comes with some rain, residents of São Paulo can look forward to warm and dry weather over the weekend, influencing outdoor activities and events such as music festivals. This could also reflect broader climatic trends that affect seasonal transitions in urban areas, where variations can lead to changes in planning for both residents and event organizers alike.
