What do the flags mean?
The green flag indicates good bathing conditions. and that you can swim and dive without problems. It is placed when the sea is calm, there is no debris in the water or any other danger.

However, the sea can change suddenly, so no flag is permanent throughout the day.
The yellow flag is placed with a higher swell and indicates that caution should be taken during bathing. At first sight it seems that no prohibition is associated with it, but there are some details that are not known. The Civil Guard explains that it is “forbidden to bathe where the bather does not touch the bottom with his head out”.
This color will fly at the lifeguard station if the waves have a height of approximately one and a half meters or there are moderately strong currents. But the yellow flag also warns of other dangers, such as dirt, jellyfish and other marine animals.
