This month in numbers
Peru experienced its 7th warmest April on record, with an average temperature of 19.47°C, marking an anomaly of +1°C compared to the 1961–1990 baseline. The period from February to April 2026 also ranked as the 7th warmest on record, with an average of 19.56°C, an anomaly of +0.9°C. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C.
What changed
Peru's consistent warmth over the last three months aligns with a broader trend, as the country recorded its warmest year on record in 2025, with an average temperature of 20.02°C. The long-term trend for Peru shows a warming of +1.03°C against the 1961–1990 baseline. Peru's April anomaly of +1.00°C was notably warmer than the South American group average of +0.54°C, placing it as the 3rd warmest in the region for the month.
What’s driving change?
The persistent warmth in Peru is influenced by the broader global warming trend, with land warming faster than ocean contributing to the elevated temperatures. The current ENSO state is Neutral, with an anomaly of +0.11°C for February–April 2026. However, forecasts indicate a strong likelihood of El Niño developing in the coming months, with a 61% chance for May–July and a 79% chance for June–August ENSO tracker. El Niño typically brings warmer and wetter conditions to coastal Peru and Ecuador, which can lead to severe coastal flooding. Peru has also been experiencing a prolonged drought, active since September 2022, and a recent flood event from late April to early May 2026 Extreme Weather tracker.
Looking ahead
The strong forecast for El Niño in the coming months suggests a likely continuation of warmer and potentially wetter conditions for Peru.

FAQs
How is the climate in Peru changing?
Peru is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The trend rate is shown as °C per decade in the headline panel; you can also see the warmest and coolest years on file.
Where does the climate data for Peru come from?
Climate data for Peru comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.

How often is the Peru climate update refreshed?
The Peru climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
