Overview
- Mid‑July readings set new July maxima at several stations, including about 27.3 °C at Callao Airport and roughly 28–28.5 °C at Campo de Marte and Alexander Von Humboldt.
- Senamhi links the unusual heat to a developing El Niño Costero and explains that anomalous coastal sea warming was reinforced by a warm oceanic Kelvin wave and a weakened South Pacific anticyclone.
- The agency reported coastal temperature anomalies up to around +9 °C above climatology in some sites and warned that such values are highly unusual for July.
- A yellow alert for increased coastal winds covers multiple regions through July 18 and urges caution for possible dust or sand uplift and reduced visibility in affected areas.
- Forecasters expect a gradual moderation of daytime highs as southerly winds bring more moisture and cloudiness, though continued warm nights, higher UV levels and the chance of new pulses of warming remain concerns for residents.
