Reaching a blistering 36 °C along the northern coastline, Peru faces an intense new wave of extreme heat as meteorological authorities expand high-level warnings across 21 regions.
The Servicio Nacional de Meteorología e Hidrología del Perú issued a red alert spanning from Friday, November 13, through Monday, November 16, RPP Noticias reported. These unseasonal conditions, completely atypical for the current spring season, directly tie into the ongoing El Niño phenomenon active along the nation’s coastline, which authorities project will persist until mid-2027.
The meteorological service warns that scarce cloud cover toward midday will significantly elevate ultraviolet radiation levels across affected areas. Afternoon wind gusts are expected to approach 30 kilometers per hour, while forecasters do not rule out sudden rainfall along the northern coast.
