Peru Declares El Niño State of Emergency Across 22 Regions Including Cusco and Lima
Peru’s Council of Ministers declared a 60-day State of Emergency on 2 July 2026 in response to forecasts of a significant El Niño event expected to develop through the second half of 2026 and into 2027. The emergency covers 796 districts across 22 of Peru’s 25 regions, including major travel destinations - Cusco, Lima, Arequipa, Puno, and Cajamarca among them.
The declaration is preventive and preparedness-focused, not a response to disaster already in progress. Its purpose is to mobilise regional and national civil defence resources, pre-position emergency supplies, and accelerate infrastructure hardening ahead of the forecast wet season.
What El Niño Means for Peru
El Niño events bring above-average rainfall and elevated river levels to the central and southern Andes, and can cause flooding on the north coast (where La Niña normally provides drought). The effects are geographically uneven - some regions face floods and landslides while others experience drought.
For the 2026–2027 event, Peruvian meteorologists are warning of:
- Landslide risk in Andean corridors, particularly on roads linking Cusco to Machu Picchu, and routes through the Sacred Valley and Puno.
- River flooding in the Amazon basin (Madre de Dios, Loreto, San Martín), with potential disruptions to river transport and lodge access.
- Disruption to the Peruvian rail network, including the Vistadome and Hiram Bingham trains to Aguas Calientes, which operate on a track that runs alongside the Urubamba River.
Current Situation: July 2026
As of 21 July 2026, conditions across most of the affected regions are in the dry season - Peru’s central and southern Andes are typically driest from May to September. No significant flooding has been reported in the major tourist areas. The emergency declaration is precautionary.
The wet season typically begins in the Cusco region in November and intensifies through January to March. Travellers visiting between now and October are unlikely to experience the El Niño effects directly, but infrastructure works triggered by the emergency may cause temporary road closures or diversions.
Practical Advice for Travellers
Check train and bus bookings. PeruRail and Inca Rail update service status on their websites. If the Urubamba River rises significantly in the wet season ahead, rail services to Aguas Calientes (the access point for Machu Picchu) may be temporarily suspended, as occurred during severe weather in 2023. Booking refundable tickets is prudent if visiting from November 2026 onward.
Follow local civil defence updates. The Instituto Nacional de Defensa Civil (INDECI) publishes regional advisories at indeci.gob.pe. The Servicio Nacional de Meteorología e Hidrología (SENAMHI) provides weather and hydrology forecasts.
Travel insurance. Given the emergency declaration, checking that your travel insurance covers natural disaster-related disruptions - particularly trip cancellations and emergency evacuation - is important for trips planned from late 2026 onward.
Trekking routes. The Inca Trail to Machu Picchu closes each February for maintenance. El Niño conditions can extend closures or create hazards on alternative routes (Salkantay, Lares, Choquequirao). Confirm conditions with your trekking operator closer to departure.
