According to meteorologist Gabriel Rodrigues, from Portal Agrolink, Brazil is facing an intense heat wave, with temperatures expected to exceed 40°C in several regions of the Center-North of the country. This worrying scenario is worsened by the approaching end of the sanitary gap for the 2024/25 summer harvest, generating great concern among rural producers.
In the coming days, the atmospheric blockage acting over central Brazil is expected to intensify, resulting in a severe heat wave. According to Rodrigues, this situation is relatively common for this time of year, but the current intensification could cause average temperatures to be 5°C above historical records for more than five consecutive days.
In addition, relative humidity may drop to 10% in regions such as northern Paraná, MATOPIBA, southern Pará and southeastern Amazonas. Temperatures will begin to rise on Monday, with peaks above 40°C in several regions of Brazil starting on Thursday.
Prolonged drought and extreme heat threaten agriculture
Some regions have already accumulated 120 days of drought, worrying farmers. Rain is forecast for the end of September, but the situation remains critical.
Temperatures of up to 43°C in southern Mato Grosso threaten crops, requiring soil conservation and management practices, such as direct planting. This method will preserve seeds during planting, avoiding replanting caused by the intense heat in the last harvest.
In addition to impacting agriculture, the combination of extreme heat and drought increases the risk of forest fires, requiring constant monitoring. Rodrigues warns that ignition, whether human or natural, is the determining factor for fire outbreaks, despite dry brush and oxygen.
On the other hand, cold days are still expected in the early mornings and early mornings, especially in the South, with possible frost in higher altitude areas. However, Gabriel Rodrigues believes that frost is not a major risk, but the thermal amplitude can affect temperate climate fruits.
