The Uruk period proper corresponds to the layers Uruk XIV–IV, with the late phase Uruk IV lasting from about 3300 BCE to about 3100 BCE.

The end of the Uruk period coincides with the Piora oscillation, a dry period from about 3200 BCE to around 2900 BCE that marks the end of a long wetter, warmer climate period from about nine thousand to five thousand years ago, called the Holocene climatic optimum.
