Easterly waves are expected to begin forming along the Northeastern coast.

According to the new VIP Report climate of DATAGROThe next few days are expected to be rainy in the Northeast region of the country. According to the consultancy, the region has been receiving rain due to the influence of… Intertropical Convergence Zone (ITCZ), which peaks between the months of March and April, in addition to the beginning of the activity of Waves from the East.

“These waves consist of atmospheric disturbances that move from east to west, from the African coast to Northeast Brazil, favoring cloud formation and rainfall. Their peak activity occurs between May and August,” explains the consultancy. The sugarcane harvest in the North-Northeast region is nearing its end, and historically, milling in the region begins to decline from April onwards. By the first half of March, 46.89 million tons had been milled, a 1.4% decrease compared to the same period of the 2024/25 harvest. The 2025/26 harvest had a late start due to rains that extended until mid-October. The climate forecast indicates that more rain is expected in the region in the coming days, with an intensification of the Easterly Waves phenomenon. According to INMET's COSMO model, next week will be rainy, especially in Rio Grande do Norte, which could register an accumulated volume above 100 mm. In Paraíba, rainfall totals could range between 70 and 100 mm, while in Pernambuco volumes between 30 and 60 mm are expected. In Alagoas and Sergipe, rainfall is expected to be weaker. The scenario is expected to remain similar for the following weeks of April. Rainfall is expected to continue to be more intense in Rio Grande do Norte and Paraíba, and weaker in Sergipe and Alagoas, with possible intensification at the end of the month. "Given this scenario, sugar mills are expected to face difficulties in completing sugarcane harvesting operations, especially in the northernmost states of the region," he adds.
