A weather station located on land is shown at sea
The Cartagena weather station 08434 should be in this town on the east coast of Spain.
But Windy shows it at sea, 95 NM more East. The reason is a wrong longitude in the database:
Instead of E 0°59’12 ‘’ the correct longitude is W 0°59’12’’.
BTW Great Dun Fell weather station is still in the wrong location
