In an interview with g1, meteorologist Francisco Assis reported that, during El Niño, high temperatures will be intensified, especially during the dry period, which continues until September. "The phenomenon [El Niño] is already active and contributing to high temperatures. We are in July and, by the month of August, temperatures should reach 40 degrees in Palmas." The cold air masses that cause the temperature drop in some regions of the country do not reach the state because they are deflected by the winds. "The wind pattern at this time of year always pushes masses of cold air towards the ocean, bypassing Palmas. Sometimes, it only reaches some regions in the south of Tocantins", explained the meteorologist. According to Francisco, the presence of asphalt and the absence of trees contribute to the worsening of high temperatures in the city. See more news from the region on g1 Tocantins.
