The southern and southeastern regions of Brazil will record the so -called “onion effect”, where the day dawns cold, gets hot and is cold with the advance of the night and at dawn, according to Climatempo.
The cold air mass of polar origin, which has lowered temperatures in several states over the weekend, loses strength, which allows for elevation of temperatures again.
The South and Southeast regions were the ones that most felt the effect of the passage of the first cold air mass with autumn characteristics. Some parts of the Midwest also register in temperature.
Because of this, the lowest temperatures of this year of 2025 were recorded. Some capitals have established new records for the lowest minimum temperature and the lowest maximum temperature of the year.
The city of Urupema, located in the highest part of the Santa Catarina mountain range, recorded the first negative temperature of 2025, with -0.2 ° C. This occurred due to the passage of this polar mass.
According to data from the National Institute of Meteorology these were the Brazilian capitals that recorded the lowest temperatures of the year between April 4 and 5.
