If you see sludgy-looking stuff with an unpleasant smell on parts of the beach, don’t panic! This is an algal bloom, a natural occurrence when the sea warms up, prompting tiny organisms called algae to reproduce rapidly.
The algal bloom season typically lasts about four weeks before it dissipates. While it might be easy to mistake these blooms for sewage due to their unpleasant smell, they are entirely harmless.
