In this work, we present a study for the classification of winter crops on a nationwide perspective for Uruguay. We have analyzed Uruguay's three most widely extended winter crops: wheat, barley, and rapeseed. We have trained a classifier based on XGBoost that uses temporal series built from Sentinel-2 image data. For training, we used the information from previous years and reported the results the following year. To our knowledge, this is the first work that proposes a clear and systematic way to classify winter crops in Uruguay based on historical data without needing samples of the actual year. We have obtained high precision and recall values for rapeseed and results comparable with other regions' work for wheat and barley. © 2024 IEEE.  aCrop classification  aDecent work and economic growth - Goal 8  aRemote sensing  aResponsible consumption and production - Goal 12  aSISTEMAS DE INFORMACIÓN Y TRANSFORMACIÓN DIGITAL - INIA  aSustainable Development Goals (SDGs)  aXGBoost  aZero hunger - Goal 21 aCAL, A.1 aPRECIOZZI, J.
