The city of São Paulo has been facing, since this Tuesday (16), a period of meteorological instability marked by heavy rains, gusts of wind and sharp temperature variations.
Alerts in effect indicate a risk for storms at the beginning of the week, followed by a change in the weather pattern starting Wednesday (17), when thermometers are expected to register a significant drop and the amount of rainfall tends to decrease.
This Tuesday, the forecast points to intense storms throughout the day, with temperatures ranging between 16°C and 29°C.

The instabilities are associated with systems that favor concentrated downpours, capable of causing localized disruptions.
The most noticeable change occurs on Wednesday, when the Paulista capital is expected to have a colder day, with a maximum around 21°C and minimum of 15°C, along with a decrease in the frequency of rains.
Heavy Rains And Risk Of Flooding At The Beginning Of The Week
The meteorological pattern expected for the beginning of the week indicates the possibility of heavy rains in a short period, a condition that historically increases the risk of flooding on urban roads and tree and branch falls.
Official meteorological alerts mention accumulations that can reach 30 to 60 millimeters per hour or 50 to 100 millimeters per day, accompanied by strong winds.
According to guidelines from the Civil Defense, in such situations it is advisable to avoid travel during heavier rain moments, as well as to be especially cautious in areas with a history of flooding or slopes prone to landslides.
The alerts also reinforce precautions such as keeping a distance from trees, metal structures, and electrical wiring during storms.
In case of emergencies, the recommended contacts are Civil Defense, via phone 199, and the Fire Department, at 193.
Temperature Drop Changes The Climate Pattern In São Paulo
Wednesday is expected to mark the clearest transition in weather behavior throughout the week.
The forecast indicates a day without significant rain and with lower temperatures compared to the previous days.
The reduction in the maximum, of nearly 10°C compared to Tuesday, should be particularly noticeable in the early hours of the morning and at the end of the afternoon.
On Thursday (18), the scenario remains similar, with cloudy skies and mild temperatures.
Thermometers should fluctuate between 17°C and 23°C, with no indication of storms.
Although cloudiness persists, models do not indicate significant rainfall volumes for this period.
By Friday (19), there is a forecast of light and isolated rain, with a gradual increase in temperature.
The maximum may reach 25°C, indicating that the colder period tends to be brief, even though the weather remains unstable at times.
Strong Winds Are On The Radar Of Authorities
In addition to the rain, the alerts in effect highlight the occurrence of strong winds associated with areas of instability.
At certain times, the gusts may range between 60 and 100 km/h, a condition that increases the risk of tree falls, damage to structures, and interruptions in the supply of electricity, according to previous records in similar situations.
For Wednesday, there is also a specific warning of strong winds, with winds estimated between 40 and 60 km/h.
Although classified as of lesser intensity compared to the storms at the beginning of the week, the phenomenon still requires attention, especially in wooded areas and with high pedestrian circulation.
New Thermal Oscillation Expected For The Next Days
After the cooler period midweek, the forecast indicates a new gradual increase in temperatures.
On Saturday (20), the weather is expected to remain unstable, with light rain and a maximum around 26°C, while the minimum stays close to 19°C.
On Sunday (21), the scenario points to a rise in heat again, with a maximum near 30°C and a possibility of rain showers throughout the day.
The following Monday is likely to have sun among clouds and even higher temperatures, reaching 31°C, indicating a return to the typical heat pattern of December in the Paulista capital.
Meteorologists emphasize that, in transitional periods like this, the intensity and timing of rains can vary throughout the day.
Therefore, the recommendation is to keep up with frequent updates on the forecast, especially for those who depend on public transport, work outdoors or need to travel during peak times when the combination of rain and wind tends to affect urban mobility.
With alerts in effect, a temperature drop forecasted, and new oscillations on the horizon, how can the population of São Paulo prepare to deal with a week marked by rapid changes in weather?
