SP has a day with bad air and a drop in temperature – 05/08/2022 – Daily life

Before a week that is forecast to be cold and more intense rains, the city of São Paulo had a day with bad air quality, rain showers and a drop in temperature.

During much of this Friday (5), the measurement by Cetesb (Companhia Ambiental do Estado de São Paulo) showed that the air quality in the metropolitan region was bad.

The situation changed during the afternoon, when rain showers reached places such as Grajaú, in the extreme south of the capital, the location, today, with the highest concentration of pollutants in the entire metropolitan region.

Cetesb classifies air quality on a scale that goes from N1-good to N5-poor. Among them are N2-moderate, N3-bad and N4-very bad.

With the rains this afternoon, air quality, in most of the city, went to moderate. In addition, temperatures plummeted. In Parelheiros, also in the extreme south, thermometers, which marked 20°C at 1 pm, pointed to 14°C at 5 pm.

Workers passing through the Parelheiros Terminal complained of the cold and claimed to have been taken by surprise by the sudden change in weather.

Pedagogue Alessandra Freire, 21, said she didn’t expect time to turn around. “Lucky I had a coat and scarf in my bag.” The umbrella was forgotten at home. “The weather was so dry during the week. Who expected?” she says.

Lúcia Guardani, manager of the air quality division at Cetesb, says that even air classified in a moderate situation can already cause discomfort in people with respiratory diseases. “The most important thing is to pay attention and follow all appropriate recommendations to avoid further damage to health”.

On its website, the company indicates that, in these situations, people with heart or lung conditions should reduce heavy exertion outdoors. In addition, it says that those with respiratory diseases may experience symptoms such as a dry cough and tiredness.

Air quality should improve next week, when the formation of a low pressure area near the coast of São Paulo should cause unstable weather in Greater São Paulo, with cold and rain showers.

According to Thomaz Garcia, meteorologist at the CGE (Climate Emergency Management Center) of the São Paulo City Hall, the forecast is for cloudy to overcast skies on Saturday (6), when there is no expectation of rain.

Thermometers oscillate between 13°C and 20°C. On Sunday (7), cloudy skies with some openings of sun between late morning and early afternoon. At night, there is a chance of drizzle. Minimum of 14°C and maximum of 22°C.

Between Monday (8) and Wednesday (10), there is forecast of rain with more intensity than this Friday, “which will improve air quality in São Paulo”, says Garcia. The trend is for lower temperatures compared to the first week of August.
