Short summary

This study improves the monitoring of extreme sea surface temperature events in the Iberia–Biscay–Ireland region. We tested new data sources and combined information from different models and satellites to provide more consistent results and characterize inter-product spread. The findings show that these methods make the indicator more reliable and useful for supporting climate and ocean management decisions.
