Rip currents are the leading cause of drowning at beaches worldwide and most international tourists don't know how to spot them. As a coastal vacation rental host, including clear rip current safety information in your welcome book — with visuals — could save your guest's life.
How to spot a rip current (visual guide)
A rip current usually looks like a calmer, choppier channel of water cutting straight out through the surf line, often flanked by breaking waves on either side. Guests should also watch for a patch of discoloured, sandier water, or foam and seaweed drifting steadily seaward rather than rolling in with the waves.
If someone is caught in a rip, the instinct to swim straight back to shore is exactly wrong — it exhausts swimmers fighting a current that can move faster than an Olympic swimmer. The correct response is to swim parallel to the shore until free of the current, or float and signal for help by raising an arm.
Rip currents can shift location with the tide, so a stretch of beach that looked calm in the morning may develop a rip by afternoon. Encourage guests to check with lifeguards on duty rather than relying purely on their own read of the water, especially at unfamiliar beaches.
"See a calm, darker strip of water between the breaking waves? Don't swim there — it may be a rip current. If you're caught in one, swim parallel to the beach, not against it."
Beach flag systems across Europe: a comparison
Flag systems are not standardised across Europe, and a red-and-yellow flag combination that means "lifeguarded safe zone" on a British beach can look confusingly similar to warning colours used elsewhere. Guests who learned one system on a previous holiday often misapply it, so it's worth spelling out the local convention explicitly.
| Flag | General meaning |
|---|---|
| Green | Low hazard, calm conditions |
| Yellow | Moderate hazard — currents and/or waves |
| Red | High hazard — swimming discouraged or prohibited |
| Red and yellow flown together | Lifeguarded zone (UK/Ireland convention) |
| Checkered black/white | Surf craft area, not for swimming |
Note the lifeguard patrol hours in your welcome book too, since a beach can look identically unguarded whether it never has lifeguards or simply had them earlier that same day.
Jellyfish safety: what guests should know
Rinse a jellyfish sting with seawater, never fresh water, since fresh water can trigger any remaining stinging cells to fire. Remove visible tentacle fragments with a card or gloved hand, not bare fingers, then soak the area in hot water (around 45°C/113°F) for 20–30 minutes if possible.
Call 112 immediately for difficulty breathing, widespread swelling, a sting affecting the face, or any sting in a young child or a known allergy sufferer. Most stings along European coasts are painful rather than dangerous, but guests appreciate knowing exactly when to worry.
Warn guests that a jellyfish washed up on the sand can still sting even if it looks dead, since stinging cells stay active for hours out of the water — bare feet and curious children are the most common victims.
Dogs on the beach: rules by country and season
Many European coastal municipalities restrict dogs from busy beach sections during daytime in the peak summer months, while off-season or designated dog beaches allow dogs off-leash year-round. Because these rules differ from country to country and even town to town, list the exact local dates, locations, and leash requirements in your guest guide rather than assuming guests will find the signage.
Note where guests can pick up waste bags too — a small detail that prevents an awkward encounter with a neighbour.
Swimming with children: what to include in your guest guide
Teach children to recognise flag colours before they even reach the water, and set the expectation with parents that children stay within arm's reach of an adult regardless of flag colour. A swim vest is worth recommending, especially on unguarded beaches or in uncertain weather.
Point guests toward any shallower, sheltered stretch of beach that's better suited to young children than the main swimming area, and note the location of the nearest first-aid post or lifeguard station.
A short checklist tends to stick better than a long paragraph: check the flag, put the swim vest on, stay within arm's reach, and skip the water entirely if in doubt. Parents scan and remember a checklist far more readily than dense safety text during a busy holiday.
FAQ
What exactly does a yellow flag mean?
It means swimming is allowed but hazards such as currents or rough surf are present. Only strong swimmers should go in, and everyone should stay close to shore.
Is it safe to swim if no flag is flying?
Not necessarily — no flag usually means the beach is unguarded, not that it's safe. Advise guests to head to a lifeguarded section if they're unsure.
How do I tell a rip current apart from a normal current?
Look for a calmer, darker channel with less breaking wave activity, often carrying foam or seaweed out to sea. When in doubt, don't swim there.
Should guests call 112 for every jellyfish sting?
No — most stings are painful but not dangerous. Call immediately for breathing difficulty, severe swelling, or a sting affecting a child or known allergy sufferer.
Where can guests check the current flag status for the beach near my property?
At the lifeguard station on the beach itself, or via the local council/lifeguard service website — include that link or address directly in your welcome book.
