Weather trends for the month of November in Brazil

RIO DE JANEIRO, BRAZIL – Systems will influence the development of humid corridors and therefore persistent and heavy rainfall in the north of São Paulo, Triângulo Mineiro, west and center of Minas Gerais, north of Rio de Janeiro, south of Goiás, northern half of Mato Grosso do Sul, Mato Grosso, far southwest of Bahia and central Tocantins.

In the southern half of the country rain will fall below average, with irregular precipitation.

SOUTHERN REGION

The month of November will be marked by irregular rainfall in the region. The trend shows that the cold fronts forming on the Argentine and Uruguayan coasts will pass quickly over the South Region, resulting in unevenly distributed rainfall in the three states, thus the monthly accumulations should fall below average in virtually all areas.

Due to the little rainfall, temperatures should be higher than average for the month, particularly in the state of Rio Grande do Sul. Temperatures in the north and east of Paraná and in the east of Santa Catarina will be within or slightly below average.

SOUTHEAST

Summer rains will prevail in most of the region. Between the north of São Paulo and the west of Minas Gerais, rain should be frequent and heavy, with accumulations above the historical average. In the other areas, rainfall will be isolated and punctual with accumulations below the average for the period.

Rainfall will remain below average in areas of the center-south of São Paulo state, due to the cooling of the waters of the equatorial Pacific Ocean – characterized by La Niña – and the warming of the waters of the South Atlantic Ocean near the southeast coast, between Rio de Janeiro and Espírito Santo.

With La Niña, the central southern areas of the country, including the 3 southern states and part of Mato Grosso do Sul and São Paulo will have irregular rainfall throughout the month.

In addition, with the warming of the southeast coast, the cold fronts will pass quickly through the South of the country, settling for a longer period over the Southeast, maintaining the channeling of the moisture flow from the interior of the country directed to the north of São Paulo and the Triângulo Mineiro, reaching part of the Zona da Mata of Minas Gerais and a small part of Rio de Janeiro, between the coast and the mountainous region of the state.

MIDWEST REGION

The month of November will be marked by more regular rainfall and with above average accumulations, mainly in central, western and southern Mato Grosso, southern Goiás and northern Mato Grosso do Sul. November will see more rain and slightly below average temperatures, due to a greater presence of clouds.

In the Midwest Region, this sequence of successive rainy and cloudy days is called “wintering.” Attention to the risk of wintering in November, when the weather is overcast for 4 days or longer, with low temperatures for the season.

In the second week and beginning of the third week of November, rainfall will become more intense and widespread across the state of Mato Grosso, and in these forecast periods there are conditions for wintering particularly in the central, southern, eastern and northern parts of the state, precisely.

Humidity flows from the Amazon will favor the occurrence of several days of heavy rainfall in the north of Mato Grosso do Sul, Mato Grosso, Goiás and the Federal District. In these areas the monthly total should exceed the average.

Rainfall will be below average, due to somewhat irregular rainfall (although not implying the absence of rain) in areas in the far east of Mato Grosso, north of Goiás and in the southern half of Mato Grosso do Sul.

NORTHEAST REGION

The month of November will be marked by heavy rains and above average accumulations in Maranhão, far southwest and east of Bahia and north-central Piauí. It will also rain in the rest of the region, albeit less frequently and the accumulated rainfall should be closer to the average. On the other hand, in the interior of Bahia and the south of Piauí, rainfall will remain below average. Heat will persist throughout the month in all areas of Northeastern Brazil.

NORTHERN REGION

With the influence of La Niña, atmospheric circulation will favor frequent and heavy rainfall throughout the region, with above average rainfall. The weather will be hot, with slightly below average temperatures in the southern half of the region, such as Acre, Rondônia and southern Amazonas, and above average in northern Pará, Roraima and Amapá.
