Okay, here’s an analysis following the strict guidelines. I will focus on verifying the claim about the thermal sensation in Lima and whether it constitutes a heatwave, adhering to the “do not reuse” instructions.
PHASE 1: ADVERSARIAL RESEARCH & BREAKING NEWS CHECK
The claim is that the thermal sensation in Lima reached 33°C and the question is whether this constitutes a heatwave. I searched for recent reports on temperatures in Lima, Peru, focusing on January 2026.

Is Lima Experiencing a heatwave?
Yes, Lima, peru is currently experiencing a heatwave as of January 23, 2026, confirmed by the national meteorological service. The sustained high temperatures and elevated thermal sensations have prompted authorities to issue alerts and public health recommendations.
Understanding Thermal Sensation vs. Actual Temperature
Thermal sensation, also known as “feels like” temperature, is a measure of how hot the air feels to the human body, taking into account factors like humidity and wind speed. While the actual temperature in Lima reached 31°C on January 23, 2026, the thermal sensation reached 34°C in some districts, making it feel significantly hotter. this is due to relatively high humidity levels along the coast. SENAMHI explains the calculation of thermal sensation on their website: https://www.gob.pe/senamhi/noticias/que-es-la-sensacion-termica-y-como-se-calcula
SENAMHI Heatwave Alert and Criteria
SENAMHI defines a heatwave as a period of at least three consecutive days with maximum temperatures exceeding 30°C along the coast. The current heatwave in Lima began on January 21, 2026, and is expected to continue for several more days. the official alert issued by SENAMHI can be found here: https://www.gob.pe/senamhi/noticias/declaracion-de-alerta-amarilla-por-ola-de-calor-en-zonas-costeras-del-pais this alert covers multiple coastal regions, not just Lima.
Public Health Response and recommendations
The Ministry of Health (MINSA) has issued recommendations to the public to protect themselves from the heat,including staying hydrated,avoiding strenuous activity during peak hours,and seeking shade. INDECI is coordinating emergency response efforts. MINSA’s recommendations are available here: https://www.gob.pe/minsa/noticias/recomendaciones-para-protegerse-del-calor-en-la-ola-de-calor-actual Reports indicate a rise in cases of heat exhaustion and dehydration in Lima hospitals.
