How this is measured
Daily sea-surface observations at the 14:00 term, averaged over 1996-2025. A station appears here only when at least 20 of those years carry a full month of readings; stations with a shorter series are left out rather than averaged into a normal they cannot support. The Croatia-wide figure is the unweighted mean of the stations shown, not a coastline average.
