In January 2022, two people were killed in Lambayeque, where the tsunami caused by the eruption of Hunga Tonga–Hunga Ha'apai measured 2 metres (6 ft 7 in).

The Lambayeque Valley is the site of natural and man-made waterways and is also a region of about 250 decaying and heavily eroded mud-brick pyramids.

Lambayeque has a hot desert climate (Köppen: BWh)[3] characterized by warm temperatures throughout the year and extremely low precipitation.

Dating from around 2000 BCE, the Ventarron temple is one of the oldest found in the Americas, as reported by the Peruvian archeologist Walter Alva.
