Beach Safety: What Every Family Needs to Know Before the Summer

The Risks Families Underestimate

British beaches are among the most beautiful and accessible recreation spaces in the country, and beach visits are a core part of many families' summers. They are also environments where drowning, injuries, and medical emergencies occur every year, often to people who visit regularly and consider themselves experienced.

The risk factors that matter most on a beach are not always the ones families anticipate. Rip currents, incoming tides, cold water temperature, and the deceptive appearance of the sea on a calm day account for far more incidents than the occasional dramatic wave. Understanding these specific risks before you arrive is genuinely protective.

Rip Currents

A rip current is a channel of water flowing away from the beach, out to sea, through a break or gap in a sandbar or reef. Rips are the leading cause of drowning in the sea and are commonly misunderstood. They do not pull people under the water: they pull people away from shore.

Rip currents are often visible as a darker, rougher, or foamy channel of water moving away from the beach, or as a gap in the breaking wave pattern. They are frequently found on either side of structures like piers and groynes, and in gaps between sandbars where the returning water finds the path of least resistance.

If you are caught in a rip current, the instinctive response (to swim directly back to shore against the current) is also the most dangerous one. Rips move at up to two metres per second: a faster speed than most competitive swimmers can maintain, and far beyond what a casual swimmer can sustain long enough to escape. Swimming against a rip is exhausting and does not work.

The correct response is: do not panic. Float and signal for help if there are lifeguards. If you need to swim, swim parallel to the shore (across the rip current, not against it) until you are out of the current, then swim diagonally back to the beach. Alternatively, allow the rip to carry you out to calmer water beyond the breaking waves, then swim diagonally back to shore.

Teaching this to older children and teenagers before they swim in the sea is genuinely important. The scenario is manageable if you know what to do, and potentially fatal if you respond instinctively in the wrong direction.

Understanding Beach Flags

RNLI lifeguarded beaches use a flag system to communicate conditions. Red and yellow flags mark the area patrolled by lifeguards: this is the safest area to swim. A red flag means it is not safe to swim at all. A black and white chequered flag marks areas for surfboards, body boards, and kayaks (not safe for swimmers). An orange windsock indicates offshore wind conditions (dangerous for inflatables).

Swim between the red and yellow flags if they are present. If there are no lifeguards on a beach, this is important information: proceed with greater caution and knowledge of the specific beach's hazards.

Tides and Tide Times

Incoming tides have caused deaths on beaches where families have been cut off on a headland, in a cove, or beneath cliffs that are inaccessible at high tide. The speed at which tides can cut off access varies dramatically by beach: in some locations, a low tide that appears to offer easy access to a beach can be cut off within an hour as the tide rises.

Before visiting any beach, particularly one involving walking out to headlands, exploring sea caves, or accessing areas that may be below cliffs, check the tide times for that specific location. Tide times are available from the BBC weather website, the Met Office, and the RNLI. Plan to leave any potentially tide-affected area with significant margin before the tide turns.

Supervising Children in and near the Sea

Children should be within arm's reach of an adult in any sea conditions other than very shallow, flat water. The sea is unpredictable: a wave that appears manageable can knock a young child over and the undertow can prevent them from righting themselves quickly. Children who are knocked over in shallow water can drown.

Inflatables present specific risks in the sea, particularly any offshore wind that can carry inflatable dinghies, rings, and airbeds away from the beach faster than someone can swim to retrieve them. The RNLI specifically advises against using inflatables in the sea.

Designate one adult as the water watcher at all times when children are in or near the sea. Rotate this role if needed, but ensure it is always explicitly assigned to someone who is not distracted by conversation, a book, or a phone.

Sun and Heat Safety

Sun protection matters throughout the day on a beach, not just at midday. UV radiation reflects off water and sand, extending exposure in ways that are easy to underestimate. Apply sunscreen with at least SPF 30 (SPF 50 for children and fair skin) before going onto the beach, and reapply every two hours and after swimming.

Dehydration and heat exhaustion are real risks on hot beach days, particularly for young children who may not reliably communicate thirst. Ensure everyone drinks regularly and retreats to shade during the hottest part of the day. Signs of heat exhaustion include pale, clammy skin, dizziness, nausea, and headache: move the person to shade, cool them with water, and give them fluids. If symptoms worsen or they lose consciousness, call 999.

If Something Goes Wrong

If someone gets into difficulty in the sea, call 999 (or 112) and ask for the Coastguard. Do not attempt to swim out to them unless you are a trained lifeguard: this is the rule that saves two lives rather than losing two. Use anything available to throw as a flotation aid. Signal to any lifeguards immediately.

If you need the emergency services at a beach location, knowing the nearest beach access name or the What3words location of your position (available on the free What3words app) will help emergency services find you more quickly than a general description of the beach.
