Peru has experienced historic temperature spikes and heatwaves, with levels in several coastal regions surpassing benchmarks set during previous El Niño events in 1997, 2016, and 2023. In late August 2026, Senamhi reported record daytime highs in areas such as Tumbes, La Libertad, and Lima, while the highlands saw temperatures not recorded in over six decades.

By early September, the heat persisted, particularly in Lima, where temperatures reached unusually high levels for the winter season. This trend is attributed to the El Niño Costero phenomenon. In the district of Carabayllo, thermal sensations reached 30°C, and some stations recorded temperatures 8.5°C above the seasonal average. Senamhi noted that the country had experienced 97 consecutive warm days, prompting authorities to issue recommendations for sun protection due to intense solar radiation.
