Lifeguards
Bathing season runs between the 1 June until 15 September.
During this time lifeguards safeguard the specific bathing areas on Seapoint, Sandycove, Killiney Bay beach and, new to DLR Lifeguarding in 2025, The Dun Laoghaire Baths. Locations are lifeguarded 12pm to 6pm weekdays and 11am to 6pm on weekends and bank holidays. Signage can be found in all 4 locations designating the bathing area boundaries. Look out for the lifeguards this summer.
Throughout the year, 9 locations are regularly sampled to monitor the water quality - Blackrock Baths Shore, Seapoint Beach, Dún Laoghaire Baths, Sandycove Beach, The Forty Foot Bathing Area, Coliemore Harbour, Killiney Beach, White Rock Beach, and Corbawn Strand. Samples are tested for E Coli and Intestinal Enterococci weekly during the bathing season and twice monthly outside of bathing season.

Jellyfish can pose a danger at bathing locations. Always listen to the advice of the lifeguards on the beach regarding jellyfish.
