Cold Front Hits Paraná While Goiânia Swings from 15°C to 31°C

A low‑pressure system moving off the Argentine coast will bring rain to southern Paraná on Monday, followed by a polar air mass that pushes temperatures down across the state. In the northern half, highs may reach 30 °C, while the metropolitan area of Curitiba and the coastal zone will stay between 17 °C and 20 °C. The western and southwestern regions are expected to see overnight lows below 10 °C, with brief frosts possible near Palmas.

In the city of Apucarana, temperatures on Tuesday will range from 10 °C to 20 °C, with a southwest wind of about 7 km/h and no rain forecast. The broader Paraná region will experience a firm, dry day as the frontal system moves offshore.

Meanwhile, Goiânia in the Central‑West will see a large thermal amplitude on the same day, with morning temperatures of 15 °C rising to 31 °C by the afternoon. Relative humidity will drop from about 90 % in the morning to 30 % in the heat of the day, prompting health advisories for dehydration and respiratory discomfort, especially for children, the elderly, and those with existing conditions.
