Short summary
We show for the first time that coastal upwelling occurs along the Uruguayan coast throughout the year, not only in summer. Using an ocean model and observations, we identify events that cannot be detected from temperature alone outside the warm season. These findings improve our understanding of local ocean conditions and their potential effects on marine communities.
