Peruvian region of Lambayeque endures extreme autumn heat, with temperatures soaring above 35°C

Peru's Lambayeque region has been grappling with an unusually intense heatwave, even as the autumn season typically brings cooler weather. On May 12th and 13th, 2026, several towns within the department registered scorching temperatures, with Tongorrape recording a peak of 35.3°C, making it one of the hottest days of the year. This extreme heat, coupled with a complete absence of rainfall, has raised concerns about the unusual climatic conditions.

According to the National Meteorology and Hydrology Service (Senamhi), multiple locations surpassed the 33°C mark. Pasabar in Olmos recorded 35.1°C, Jayanca hit 35°C, and Motupe reached 34.9°C. Other areas like Oyotún, Cayaltí, and Tinajones also experienced temperatures well above 33°C. This widespread heat across the coastal districts paints a stark picture of an unseasonably hot period, challenging the typical autumn climate.

Interestingly, the thermal conditions varied dramatically between the coast and the highlands. While coastal areas sweltered, with minimum temperatures hovering around 20-22°C, the higher-altitude zones of Lambayeque, such as Incahuasi, experienced sharp drops, with nighttime temperatures plummeting to as low as 7°C. This significant contrast highlights the diverse microclimates within the region and the complex interplay of weather patterns.

The extreme heat in Lambayeque serves as a stark reminder of the unpredictable nature of climate and its impact on daily life. While the article focuses on the temperature readings, the implications for agriculture, water resources, and public health in a region heavily reliant on its natural environment are considerable. The juxtaposition of extreme heat on the coast and cold in the highlands underscores the unique environmental challenges faced by Peru.
