Brighton basked in glorious sunshine today, with temperatures peaking at a toasty 24°C (75°F) and barely a cloud in the sky. The seafront was packed with sun-seekers and swimmers looking to cool off in the glistening sea. But while the weather brought the perfect backdrop for a beach day, the RNLI issued an urgent warning for those tempted by a risky seaside thrill.
Lifeguards and rescue teams have urged the public not to jump off the groynes, particularly during high tide. The structures that line Brighton beach may look like tempting platforms for a leap into the blue, but the reality beneath the water can be far more dangerous. As the tide rises, the sea can conceal sharp rocks, shifting currents, and submerged hazards that aren’t visible from above.
Today’s high tides made the warning particularly timely. The sea reached its peak just after midday—around 1:14pm—with water levels climbing to more than five metres deep. Another high tide is expected in the early hours, at around 12:49am, but it’s the afternoon rise that coincided with peak beach activity. At this height, the water may seem deep enough to jump into, but the RNLI says this is exactly when hidden dangers pose the greatest risk.
Lifeguards patrolling the beach reported several close calls involving groups of teenagers and visitors unfamiliar with the risks. While many think they’re diving into deep, safe water, currents around the groynes can easily sweep people sideways into the wooden or stone structures. Even experienced swimmers can be caught off guard.
By late afternoon, the beach remained comfortably warm, hovering around 22°C (72°F), drawing even more people into the sea. For those keen to enjoy the water safely, the RNLI recommends sticking to designated swim zones and entering the sea from open stretches of beach, away from structures. The best time for a swim is during the hours after low tide, when the water is calmer and visibility is better.
Locals and tourists alike are being reminded: while Brighton’s iconic beach offers plenty of excitement, it’s vital to respect the sea’s power. A simple dive from a groyne could end in disaster. With more hot weather on the way, safety advice is clear—enjoy the beach, but think before you leap.
