Find out how the air warms and see the highest temperatures expected for the last day of winter 2023.
A large mass of warm, dry air expands and intensifies over Brazil. This air mass is associated with the presence of a large high atmospheric pressure system within the country. The waning air movement (from top to bottom) caused by high atmospheric pressure inhibits the formation and growth of large clouds, and with fewer clouds, less rain occurs.

The heat wave is strengthening and the temperature continues to rise.
Warm, dry air prevails in the interior of the Northeast, in Tocantins, in the Central West and in the Southeast, and also over much of Paraná.
This Friday temperatures could reach between 37°C and 40°C in much of the interior of Sao Paulo, central-west and northern Minas Gerais and in some areas of Rio de Janeiro state.

How is the air heated?
The high atmospheric pressure system acts like a lid, compressing the air near the surface, and this compression, done from top to bottom, heats the air.
Additionally, because the air is dry, few clouds form and most of the country has many hours of strong sunlight during the day. With lots of sunshine, for many hours, the air warms up quickly.
The lack of cold air is another factor that contributes to making almost the entire country very hot. The circulation of winds, at various levels of the atmosphere, pushes cold fronts away from the high seas. Cold fronts arrive forcefully in Rio Grande do Sul, but are then pushed out to sea. The polar air that arrives with the cold front is also pushed towards the sea and cannot enter the interior of Brazil, but it mixes with the warm air and lowers the temperature.
