The city of São Paulo is bracing for a shift from the extreme heat experienced over recent days to increased rainfall expected this weekend, with significant thunderstorms projected to impact the region. After enduring temperatures soaring to as high as 35 degrees Celsius, reports from Climatempo indicate the onset of this weather change is already beginning to take shape.
For the upcoming weekend, particularly on Saturday, February 22, and Sunday, February 23, the forecast suggests heavy rain persistent throughout the day. The meteorological team at Climatempo warns of the type of thunderstorms typical for the summer season — marked by sudden and intense rain, potential flooding, and even thunderstorms with lightning strikes.
According to meteorologist Fábio Luengo from Climatempo, Friday (February 21) will mark the gradual decline of the intense heatwave affecting several states, including São Paulo, with high expectations for cooling rains to settle temperatures temporarily. Although temperatures will continue to register around 30 degrees Celsius, the arrival of more humid air due to the expected downpours will bring relief from the oppressive heat.
On Thursday, February 20, São Paulo recorded temperatures hitting 35 degrees, making it one of the hottest days of the month, along with isolated thunderstorms. Luengo reported, “This is part of the third heatwave affecting the region, which has resulted in both scorching temperatures and the risk of thunderstorms.” The state's coast is also expected to experience rain, with forecasts indicating accumulated precipitation ranging from 20 to 50 millimeters by Saturday.
Warnings have been issued by the Instituto Nacional de Meteorologia (INMET), highlighting the potential for intense rain across several municipalities, including São José do Rio Preto, Campinas, and the coastal regions of the state. Residents are advised to stay alert for sudden changes, particularly as the rains could be severe enough to prompt flash floods.
For those planning to enjoy outdoor activities or partake in pre-Carnival festivities this weekend, precautions are necessary. Stefanie Tozzo, also from Climatempo, reiterated this caution, stating, “Expect occasional sunny breaks, but don’t let your guard down; there’s potential for rainfalls leading to localized flooding.”
The broader impact of the changing weather patterns highlights not just discomfort but also potential hazards. With the heatwave still looming over many areas of Brazil, there have been instances of residents trying to cool off at local water fountains, as seen recently at the Parque da Independência. Despite the upcoming rains, the feeling of humidity and temperatures can still make the climate feel oppressive.
After this weekend, starting Sunday, the forecast indicates continuous improvements and gradual reduction of precipitation, leading to clearer skies and more stable temperatures as February progresses. Nevertheless, meteorologists still predict slightly above-average temperatures for the region over the coming weeks, hinting at prolonged warm conditions before the anticipated arrival of autumn later on.
With this week’s periods of high temperatures, storms, and the accompanying forecasts, residents of São Paulo are reminded to prepare for the dynamic weather typical of summer. The combination of heat, moisture, and rain creates unpredictable conditions, potentially affecting daily routines and safety. Emergency services and civil defense units are on standby to respond to any adverse weather incidents, ensuring community safety as the situation develops.
Residents should keep themselves updated through official channels to navigate the rapid weather changes over the next few days, which could have significant impacts on plans for festivities and daily activities across São Paulo. The nuances of such unpredictable weather patterns serve as reminders of the importance of climate preparedness and awareness as summer weather continues its capricious ways.
While the current weather may pose challenges, it also brings hope for relief from the recent sweltering heat. For now, São Paulo will be caught between the remnants of its heatwave and the impending storms, leading to another chapter of its unpredictable summer narrative.
