With the Surface Detector array (SD) of the Pierre Auger Observatory we candetect neutrinos with energy between 0.1 EeV and 100 EeV from point-like sources across thesky, from close to the Southern Celestial Pole up to 60deg in declination, with peak sensitiv-ities at declinations around −53deg and +55deg, and an unmatched sensitivity for arrival directions in the Northern hemisphere. A search has been performed for highly-inclined airshowers induced by neutrinos of all flavours with no candidate events found in data takenbetween 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino flux from point-likesteady sources have been derived as a function of source declination. An unrivaled sensitiv-ity is achieved in searches for transient sources with emission lasting over an hour or less, ifthey occur within the field of view corresponding to the zenith angle range between 60deg and95deg where the SD of the Pierre Auger Observatory is most sensitive to neutrinos.
