Curlew Sandpiper breeds in open tundra habitats with marshy depressions and pools in high Arctic lowlands, along coasts and on Arctic Ocean islands. Outside the breeding season it occurs on variety of inland and coastal wetland types. Its breeding range falls within Arctic Siberia, from the Yamal Peninsula to N Chukotka (Van Gils et al. 2020). It is a long-distance migrant, moving on a broad front. The populations passing through Europe winter mostly in Africa.
