Senamhi has issued an alert for a new heat wave affecting lima, with elevated daytime temperatures recorded across the capital and the phenomenon potentially extending until March 12; the agency links the spike to local urban conditions and advises precautionary measures. The meteorology specialist Erick Rojas flagged consecutive hot days at several monitoring stations that confirm the event. Residents are urged to protect themselves, limit exposure during peak solar hours, and follow Senamhi guidance.
Heat readings in Lima
Senamhi records show the station in Jesús María reached 29. 9 °C, marking its fifth consecutive day of heat; the La Molina station logged 31. 8 °C on its fourth straight day of elevated temperatures. Other recent measurements across the metropolitan area include Carabayllo at 31 °C and San Borja at 33 °C, while some La Molina readings were reported around 30 °C. These figures underline a pattern of sustained daytime warming across districts that do not always follow the city’s typical coastal-to-inland profile.
Why central districts are heating faster
Erick Rojas, Meteorology Specialist at the Servicio Nacional de Meteorología e Hidrología del Perú (Senamhi), explained the distribution of heat: “Some meteorological stations have recorded several consecutive days under these conditions, which confirms the presence of this climatic phenomenon in the city. ” He noted that central districts such as San Borja, San Luis and La Victoria can clear earlier than coastal sectors, increasing direct solar exposure. Urban features—reduced wind circulation and a higher concentration of buildings—favor heat accumulation and sustain higher daytime temperatures.
Immediate reactions and safety advice
Rojas emphasized the difference between measured air temperature and perceived heat: “There is a difference between air temperature and thermal sensation that can raise by two to three degrees, ” he said. Senamhi recommended avoiding prolonged sun exposure between 10: 00 and 16: 00 ET, using an umbrella, wearing light cotton or long-sleeved clothing, applying sunscreen and staying hydrated. The agency also advised against taking pets out during the hottest hours to prevent heat-related emergencies.
What to expect next
The heat wave in lima could remain in place for the coming days and extend until March 12, with a change expected afterward. Senamhi indicates that the eventual arrival of winds from the south could produce a slight decline in temperatures and a perceptible increase in freshness in some sectors of the city. Authorities and residents are preparing for continued high daytime temperatures while monitoring for the anticipated shift in wind patterns and a modest cooling trend.
