Overview
- Senamhi reported on Wednesday that Lima and Callao have reached 70 straight nights of unusually warm minimum temperatures based on its monitoring stations.
- The Jorge Chávez station in Callao has logged nightly lows of about 20–21.6 °C and has recorded only 'extremely warm' nights since June 28.
- Other Senamhi sites show prolonged warm minima: Jesús María has 64 consecutive warm nights with lows near 18–20.6 °C and La Molina reports nightly values around 16.4–19.2 °C.
- Senamhi and climate specialist Lourdes Menis link the persistence to El Niño Costero-related ocean and atmospheric anomalies that keep the coastal Pacific releasing stored heat at night.
- By starting on May 6 this year the episode began earlier than the 2023 event, when Callao recorded 142 warm nights that started in June, showing a shift in seasonal timing that Senamhi continues to monitor.
