Santa Catarina will have above average temperatures in autumn

The forecast for the March to May quarter indicates above-average temperatures and below-expected rainfall in Santa Catarina. According to Epagri/Ciram, March will be marked by the continuation of hot air masses over the state, resulting in consecutive days of intense heat, including at night.

From April onwards, episodes of cold and frost are expected to occur in the high areas of the Southern Plateau. Despite the reduction in rainfall, there is a risk of severe weather events, such as storms, strong winds and extratropical cyclones.

According to meteorologist Marilene de Lima, above-average temperatures will be a predominant feature throughout the quarter. The heat will be most intense in March, influenced by hot air masses. From April onwards, the first cold air masses will begin to arrive in the South of Brazil, bringing more frequent cold spells in May.

Meteorologist Gilsânia Cruz explains that the forecast for the quarter indicates rainfall below the climatological average in Santa Catarina.

In March, prolonged periods without precipitation are expected, especially in the west of the state. Most of the rain will be caused by cold fronts, which should become more frequent in the second half of the month.

Monthly rainfall averages should vary between 100 and 130 mm in the West and Plateau, while on the Coast the accumulated amounts should be between 150 and 210 mm. In April and May, the tendency is for an even greater reduction, with averages between 100 and 170 mm in Santa Catarina.

Even with the decrease in rainfall, autumn can still see intense weather events. According to Gilsânia, the period can have heavy rains in a short space of time, as well as storms with lightning, hail and strong winds.

The meteorologist warns of the more frequent action of extratropical cyclones on the coast of Uruguay, Rio Grande do Sul and Santa Catarina, which can cause intense winds, rough seas and storm surges, posing risks to navigation.
