Peru's Senamhi Issues Red Alert for Extreme Heat on the Coast

Peru's national meteorological and hydrology service, Senamhi, issued a red alert on Oct. 31, 2026, for extreme heat up to 38 °C along Peru's coast and highlands. The alert runs from Nov. 1 to 4, 2026, RPP Noticias reported. Senamhi said the heat would be "of moderate to extreme intensity."

The alert covers 17 regions, including Lima. On Sunday, Nov. 1, 2026, Senamhi's forecast peaks at 38 °C on the northern coast. Lima and the rest of the central coast could reach 32 °C, and the southern coast as high as 30 °C.

Senamhi also said scant cloud cover expected around midday would raise ultraviolet radiation levels along the coast.

The red alert takes effect Sunday, Nov. 1, 2026. It had not yet begun when Senamhi issued it on Oct. 31, 2026.
