The RNLI says more people lost their lives on the Welsh coast than in cycling accidents.
In total, 17 people died last year, and 65 were rescued by lifeboats and lifeguards.
Since 2010, a total of 70 people have died around Wales' coast.
Adult men accounted for 73% of them.
Today the RNLI launches its Respect the Water campaign, aimed especially at men, to try and bring these figures down.
Nationally, an average of 160 people die at the coast each year. The RNLI is aiming to halve accidental coastal deaths by 2024.
