Understanding the readings

This is a sea temperature reading from a coastal station, not an average for the whole sea or a measure of water quality.

Each province shows its latest available coastal reading. Provinces and the locations listed beneath them are ordered by sea temperature, warmest first. Air temperatures match the current values on the corresponding city or district pages. Missing values appear as —. Water temperature alone does not tell you whether swimming is safe.
