El Niño 2026-2027: Is It Safe to Travel to Cusco and Machu Picchu?
El Niño 2026-2027: Is It Safe to Travel to Cusco and Machu Picchu?
Updated: October 2026, based on ENFEN Official Statement No. 17-2026.
If you are planning a trip to Peru and have seen news that an El Niño event is underway, it's natural to wonder whether you should cancel or change your dates. The short answer: El Niño mainly affects Peru's northern and central coast, not Cusco. The official forecast for the southern Andes, where Cusco and Machu Picchu are, is for normal or even below-normal rainfall. Here's what the data says and how to plan.
What El Niño is and what's happening now
El Niño is an abnormal warming of the Pacific Ocean. In Peru it is monitored by ENFEN (the National Study of the El Niño Phenomenon), an official commission that issues statements every two weeks.
According to its Official Statement No. 17-2026 (September 28, 2026):
- The Coastal El Niño Alert remains in place.
- Ocean warming off the Peruvian coast is expected to stay at extraordinary magnitude until January 2027, easing towards autumn 2027 (April-May).
- In the central Pacific, El Niño is expected to remain very strong until January 2027.
You can check updated statements on ENFEN's official page (in Spanish).
Where it will rain more, and where it won't
This is the key point. The same statement forecasts:
| Region | October-December 2026 | Summer 2027 (January-March) |
|---|---|---|
| Northern coast (Tumbes, Piura, Lambayeque) | Above-normal rain | Above-normal rain |
| Central coast (including Lima) | Above-normal rain | Above-normal rain |
| Southern Andes (Cusco, Puno, highland Arequipa) | Normal to below normal | Below normal to normal |
| Amazon | Normal to below normal | Below normal to normal |
In other words: while the northern coast may see heavy rain and swollen rivers, no extra rain is expected in Cusco. If anything, it may rain slightly less.
So there's no risk at all in Cusco?
To be honest: Cusco has its own rainy season, from November to March, El Niño or not. January and February are the wettest months, and in years of intense rain there have been problems. The best-known case is January 2010, when very heavy rain damaged the railway and the train to Machu Picchu was suspended for weeks.
The current forecast says El Niño is not expected to increase that risk in the southern Andes. But the rainy season is still the rainy season, so the usual precautions apply:
- Leave a buffer day between Machu Picchu and your departure flight.
- Choose Machu Picchu in 2 days over a day trip: if a train is delayed or the morning is cloudy, you have plenty of time.
- Book with an agency that can reschedule trains and tickets if something changes.
- Bring a poncho, waterproof shoes and layers.

What can affect you: the rest of your Peru route
If your trip includes Lima or the northern coast, that's where you should pay attention:
- Lima: ENFEN forecasts air temperatures well above normal along the whole coast, with a chance of record heat, and above-normal rain. Rain in Lima is usually light, but in the Lima highlands it can trigger landslides (huaicos) that affect roads such as the Carretera Central.
- Northern coast (Máncora, Piura, Chiclayo, Trujillo): the area at greatest risk of heavy rain, flooding and road closures.
- Flights: most travelers reach Cusco by plane from Lima (1 hour 20 minutes). That route doesn't cross the heavy-rain areas.

Cusco tours during El Niño: what to expect
| Tour | What to expect this season |
|---|---|
| Cusco City Tour (US$15) | Running normally. Afternoon rain possible from November |
| Sacred Valley VIP (US$32) | Running normally. Green valley from December |
| Machu Picchu 2D/1N (US$280) | Running normally. The most flexible option in the rainy season |
| Rainbow Mountain (US$30) | Running normally. Possible snow between December and March |
| Humantay Lake (US$35) | Running normally. Muddier trail in the rainy season |
October and November are still great months to travel: the rains are only beginning, there are fewer crowds than in July and August, and under the current forecast El Niño is not expected to change that in Cusco.
