- Beware of “baïnes” (rip currents): These powerful currents are more common in Southern Finistère, but vigilance is always advised everywhere.
- Water quality: Northern Finistère boasts excellent swimming water quality, which is regularly monitored. However, some sites may be temporarily closed due to pollution or algae blooms; always follow the instructions posted on-site.

For any water activities, check the weather and tide times, and don’t hesitate to ask lifeguards or locals for advice.
