Short summary
We explore how a semi-enclosed bay in the Humboldt Current System responds to the passage of extratropical cyclones. Using ERA5 data and acoustic Doppler current profiler observations, we found that intense north winds associated with these cyclones drive surface water into the gulf, creating pressure gradients that alter coastal currents, and may reduce residence times. This enhances our understanding of wind-driven coastal dynamics, impacting marine ecosystems and coastal management globally.
