After the spring floods, the year 2023 ends with a predominance of sunshine in the Southern Region. Cold air of polar origin refreshes the three states.
After spring floods, southern Brazil ends 2023 with mostly sunshine and little rain. After causing storms and winds this Friday, December 29, a cold front moves away from the Southern Region and cold air of polar origin spreads over the United States, reducing humidity and conditions for rain.
The presence of this cold air will leave southern Brazil cool and without thunderstorms in the last weekend of 2023. Check the weather forecast for the end of 2024.
