Abstract Submesoscale processes in the ocean typically peak in winter, driven by mixed‐layer instability and intensified atmospheric forcing. However, coastal upwelling regions can deviate from this paradigm due to region‐specific dynamics. Based on validated high‐resolution simulations, we investigate the seasonal and regional variability of submesoscale activity in the Arabian Sea. Our results reveal that the western Arabian Sea exhibits a pronounced summer peak in submesoscale activity, prima
