Turning seawater into salt by evaporating it works in areas where evaporation is substantially higher than precipitation, so mostly in dry, warm areas.
Agree Northern Europe would be tough, but there are plentiful salt ponds in Vietnam where the humidity (plus the rain) would make one think evaporation would be challenging, but apparently it works.
