This study presents the Surrogate Engine for Crop Simulations Framework (SECSF) a group of deep-learning models that emulate the process-based ECroPS model using only daily maximum and minimum temperature and precipitation. In this study we emulate grain maize and spring barley. Trained on ERA5-forced ECroPS simulations, SECSF reproduces crop growth dynamics and harvest timing with high fidelity. Critically, SECSF extremely reduces computational costs enabling ensemble-scale inference suitable for operational pipelines. When driven by seasonal data, SECSF captures the interannual and spatial patterns of crop stress across Europe and aligns with independent monitoring, supporting its use as a probabilistic Areas of Concern indicator for early warning. Under CMIP6 SSP3-7.0 and SSP5-8.5 scenarios, SECSF consistently identifies the Mediterranean basin as a persistent hotspot of yield risk through mid-century, with central-northern Europe showing mixed signals. These results demonstrate that a streamlined, data-efficient emulator can provide robust seasonal-to-climate risk assessments at continental scale.
