Weather in Brazil takes a new turn with a cold front off the Southeast coast, heavy rain in the South, storms in parts of the Southeast, instabilities in the North and Central-West, and persistent dry air in the country’s interior
The weather in Brazil has begun to change with the formation of a new cold front off the Southeast coast, a system that is expected to reorganize the weather in the coming days and reinforce the contrast between areas with excessive rain and regions under alert for low humidity. According to Climatempo, the new atmospheric configuration is associated with a low-pressure area near the coast of São Paulo and expands the conditions for moderate to heavy rain in different parts of the country.
The scenario is noteworthy because it affects Brazil broadly and unevenly. While the South and parts of the Southeast enter a phase of higher risk for storms, the Central-West and the North continue with irregular showers and areas of instability, at the same time that the interior of states in the Southeast, Central-West, and Northeast continues to face critical levels of air humidity.
What is changing in Brazil’s weather with the new cold front
The new cold front begins to form off the Southeast coast and starts to directly influence the weather pattern in the country. The system reinforces instabilities in the South and expands the condition for more intense rain in parts of the Southeast, with emphasis on São Paulo.

In practice, the change in weather appears as a national reorganization of the weather. The country once again experiences a combination of heavy rain, risk of storms, wind gusts, rough seas, and pockets of dry air inland, forming a meteorological map marked by regional extremes.
South concentrates the heaviest rain and maintains risk of storms
In the South, rain has been occurring since early morning between Paraná and Santa Catarina, mainly affecting the southern half of Paraná and the northern part of Santa Catarina, with potential for storms and high accumulations. Throughout the day, instabilities advance through areas of Paraná, the western half of Santa Catarina, and reach the extreme north of Rio Grande do Sul.
In the rest of the Gaúcho territory, the weather remains stable, but the climate continues to demand attention. Temperatures are lower in the morning in Rio Grande do Sul, rising in the afternoon, there is a chance of frost in southeastern Rio Grande do Sul, and the sea remains rough on the coast of Rio Grande do Sul and Santa Catarina.
Southeast enters the route of the new weather turn
In the Southeast, the cold front moves away to the ocean, but a new low-pressure system starts to favor rain, especially in São Paulo. The forecast indicates moderate to heavy showers in the south and on the São Paulo coast, with thunderstorms, in addition to rain on the northern coast of Espírito Santo and in parts of southwestern São Paulo, albeit with less intensity.
In the other areas of the region, the weather remains more stable. Temperatures continue to be high in much of the Southeast, but fall in southern São Paulo due to cloudiness. At the same time, the interior enters an alert for humidity below 30% in northern São Paulo, in the Minas Triangle, and in the interior of Minas Gerais, while wind gusts can reach 50 km/h between Rio de Janeiro and Espírito Santo.
Central-West mixes showers, storms, and dry air
In the Central-West, the forecast indicates early morning showers in the north, northeast, and interior of Mato Grosso. In the south and southwest of Mato Grosso do Sul, the risk is of storms, with intensification of instabilities throughout the afternoon in much of Mato Grosso and in areas of western and southern Mato Grosso do Sul.
In Goiás, the situation is different. The weather remains stable in most of the state, but the climate is concerning due to low humidity, which can fall below 30%, especially in southeastern Goiás and around Goiânia.
North continues with unstable weather and risk of storms in several states
In the North region, the presence of humidity keeps the weather unstable since early morning in states like Amazonas, Pará, Rondônia, and Acre. Throughout the day, instabilities gain strength and increase the risk of storms in a large part of the region, especially in Amazonas, Pará, Amapá, and Rondônia.
In Tocantins, rain appears more irregularly, with stable weather in part of the state. Even so, the situation reinforces the idea that the climate in the North remains far from broad stabilization.
Northeast maintains rain on the coast and dry weather inland
In the Northeast, rain is concentrated along the coastal strip between Rio Grande do Norte and Bahia, under the influence of maritime humidity. More intense showers are forecast between Ceará, Maranhão, and northern Piauí, with a risk of isolated storms.
In the northeastern interior, the weather remains dry and hot. Relative humidity also concerns areas inland, especially in southern Piauí and Bahia, maintaining the contrast between rain on the coast and dry air in areas further from the coast.
What this climate map means in practice for Brazil
The advance of this system shows a country divided between regions with heavy rain and areas where the greatest risk remains dry air. For those in the South and parts of the Southeast, the alert is for storms, thunderstorms, wind, and higher accumulations. For the interior of the Southeast, Central-West, and Northeast, the concern shifts to the drop in humidity to critical levels.
This type of configuration reinforces how the climate in Brazil can change rapidly and unevenly. The new cold front does not cause a uniform shift across the country but redistributes instabilities and deepens the contrast between areas under intense rain and regions that remain dry and hot.
Why the new cold front is drawing so much attention right now
The cold front gains prominence because it reorganizes the weather in several regions simultaneously and places the Southeast back within the area of greatest meteorological attention, especially with the new low-pressure system near the coast of São Paulo. Furthermore, the South has been facing instabilities since early morning, while the North and Central-West continue with irregular showers and storms.
The result is a national picture of strong contrast, where rain advances significantly in part of the country and dry air continues to pressure other areas. It is precisely this combination that makes the new change in climate draw so much attention in this final stretch of April.
In your region, did the new cold front bring rain, wind, and a drop in temperature, or does dry weather still predominate?
