Cold front changes weather in Campinas and ends summer spell

The Campinas region is in the spotlight of weather searches due to the arrival of a cold front that promises to drastically change the climate scenario. After a period of "summer spell", characterized by high temperatures and dry weather, the population is preparing for a drop in thermometers, stronger winds, and the return of humidity.

Cold front and the end of the summer spell

A cold front originating from a cyclone coming from the south of the country is impacting the state of São Paulo, bringing an interruption to the "summer spell". This phenomenon, relatively common in the Southeast winter, is marked by generating temperatures 3°C to 5°C above average, caused by high‑pressure systems that block cold fronts. The arrival of this new air mass promises relief from the hot, dry weather.

Temperatures began to fall in the Campinas region from Friday. On Saturday night, thermometers recorded minima of 13°C. The lowest temperature of the weekend was forecast for Sunday (23), reaching 11°C. The strong winds brought by the cyclone also contribute to the cold sensation.

Forecast for Sunday and Monday

Sunday (23) in the Campinas region was marked by a cold morning, with temperatures around 12°C, while the afternoon could reach 27°C, showing a large thermal variation. For Monday (24), the forecast is sunshine with clouds and no expectation of significant rain. Temperatures should stay mild, with a minimum of 13°C and a maximum that may reach 26°C. During the night, thermometers oscillate between 13°C and 15°C, rising to 13°C–20°C in the morning and hitting the heat peak in the afternoon, between 22°C and 26°C. At night, the gradual drop brings temperatures to 16°C–25°C.

Air humidity and possibility of fog

Relative air humidity is a point of attention. On Sunday (23), it remained low, with a minimum close to 30%, increasing the risk of vegetation fires. For Monday, humidity varies between 48% and 89%, keeping comfortable indices for the population. During the early mornings, there is a possibility of fog formation in areas with higher vegetation cover and lowlands, including road sections, which should dissipate by morning.

Important recommendations

Given the temperature variation and weather conditions, some precautions are recommended. On low‑humidity days, it is essential to reinforce hydration and avoid intense physical activities during the hottest hours. The temperature variation throughout the day, especially on Monday, requires attention to clothing choices, with lighter layers that can be removed as the day warms up. For drivers, in case of fog, it is crucial to reduce speed and maintain a safe distance from other vehicles while visibility is low.

Benefits of the climate change

Despite the necessary adaptations, the arrival of the cold front and increased humidity bring benefits. According to meteorologist Bruno Bainy, humidity and lower temperatures should reduce the incidence of fires, which are a risk in dry periods, and may also decrease the occurrence of some respiratory diseases.
