Minimum-6.9°C! Low-temperature frosts have occurred in central and southern Brazil for several consecutive days

A cold wave has plagued south-central Brazil since last week, according to local media reports. Last week, a large amount of polar air poured in from southern Brazil, and this week, a large temperate cyclone over the South Atlantic pushed a stronger puff of polar air into Brazil.

At present, winter precipitation has been recorded twice in southern Brazil, first snow and freezing rain in the southern part of the Santa Catarina plateau. Later, snow and freezing rain were also reported in the city of San Jos é dos Osentes, Rio Grande do Sul.

With the invasion of cold air, the climate has dropped sharply, and the lowest temperature recorded in Brazil has remained at the lowest level in recent days, with the lowest temperature of-6.8 °C in Santa Catarina and-5.3 °C in Rio Grande do Sul.

In addition to the south, temperatures have also dropped in central, western and southeastern Brazil, with temperatures falling to 0.0 ℃ in the interior of Mato Grosso Sul. Sao Paulo and Rio de Janeiro suffered their coldest weather in August in 13 years, and the lowest temperature in Rio de Janeiro dropped to 8.3 ℃, according to official data from the National Meteorological Institute, which is very cold by the city's climate standards.

But the worst is in the mountains of the southern state of Minas Gerais, where the cold wave set a record for the lowest temperature in Brazil, with the lowest climate observed by the observatory reaching-5.8 °C, while the temperature recorded by the weather station was even lower, reaching-6.4 °C to-6.9 °C.

In addition, the cyclone also affected the port of Santos, Brazil's main port, and it is reported that waves have continued to occur in the waters from Santa Catarina to Esp í rito Santo, with waves up to 4 meters high. As a result, cargo ships entering and leaving the port of Santos had to be suspended due to adverse weather conditions, exacerbating delays at the port.

Generally speaking, the winter in Brazil is from June to August, and will end on August 31, but the meteorological department believes that it will not end until the Spring Equinox on September 22nd, so the winter will last for several weeks. The meteorological department expects that there will still be cold weather in the next few weeks, and there may even be even colder weather. There will be a new round of low temperatures in the second half of August, and the southern region of Brazil will be more affected. It is also worried that the upcoming La Nina phenomenon will aggravate the bad weather in Brazil.

At present, the progress of coffee harvest in Brazil is nearing the end of the new season, but the market is still worried that the frost will affect this year's coffee harvest, as well as the growth of coffee in the new season of 2025x26. Especially for Arabica varieties, the low temperature-affected mountains of Minas Gerais are mainly Arabica growing areas, so the futures prices of Arabica and Robusta coffee have soared in recent days.

All because the current frost will also bring rain, rain before cold weather may cause coffee trees to blossom prematurely, making them vulnerable to frost damage. If there is not enough rainfall, drought will also hinder the growth and development of coffee plants, resulting in a decline in coffee quality and yield.

Earlier, Brazil experienced the weather effects of drought and little rain, and there was a shortage of coffee beans during the coffee harvest in 2024, resulting in a decrease in output, so a number of Brazilian institutions have reduced Brazilian coffee production in the new growing season. coupled with the current low temperature report, coffee futures prices may increase significantly.
