In view of the orange weather warning for the heatwave, the Ministry of Sports reminds people of essential safety measures for swimming. Prefer supervised areas, keep a close eye on children, and respect swimming zone signage.
Emergency instructions
112: European emergency call number.
18: Firefighters.
196: Maritime rescue from the coast. Use VHF channel 16 when at sea.
With the intense heat, the desire to cool off in water increases. To enjoy swimming safely:
- Prefer supervised swimming areas and never swim alone.
- Take into account your physical condition and do not overestimate your physical abilities.
- Always accompany children in the water and remain attentive to their proximity.
- Stay alert to currents and hidden dangers near lakes or the sea.
- Strictly respect swimming prohibitions and on-site signage.
According to Santé publique France, between 1 June and 30 September 2025, 1,418 drownings were recorded in France, including 409 deaths (29 %). These figures represent a +14 % increase compared to the same period in 2024.
Drownings are the leading cause of death from non-traffic accidents among people under 25 years of age.
To prevent risks:
- Learn to swim at any age, under the supervision of a certified swimming instructor.
- Designate one adult exclusively responsible for supervising children.
- Inform yourself about swimming conditions (currents, natural hazards) before entering the water.
- Check real-time weather forecasts via the websites windmorbihan.com, windcornouaille.com, and windloireatlantique.com.
- Avoid alcohol, excessive sun exposure, and swimming if you feel cold or experience physical disturbances.
- Enter the water gradually, especially if it is cold.
