Marbella has turned heads once again. Spotted off the coast of Puerto Banus, the magnificent 110-metre megayacht Kaos, owned by American billionaire Walmart heiress Nancy Walton Laurie, has drawn crowds of onlookers to the glamorous marinas, arriving in convoy with its 67-metre support vessel, Kalm.

A floating palace with Qatari royal origins

Kaos carries an eye-watering price tag of around €300 million, making it one of the most spectacular and valuable private vessels in international sailing. Originally built in the Netherlands by renowned shipyard Oceanco, the vessel was commissioned for the late Emir of Qatar, Sheikh Khalifa bin Hamad bin Abdullah Al Thani, before later passing into Walton Laurie’s hands.

Onboard services are designed to rival those of an ultra-luxury hotel, comfortably accommodating up to 31 guests across 15 premium cabins, including an exclusive master suite located on an entirely private deck. A dedicated crew of up to 45 professionals keeps things flawlessly running. World-class amenities include a fully equipped gymnasium, a luxury spa, a guest lift, an onboard cinema room, a certified helipad, and a private medical bay.

The optical illusion that stops people in their tracks

Much of Kaos’s fame rests on her extraordinary exterior, the work of Barcelona-based designer Igor Lobanov, who has said he “was allowed to do anything he wanted.” Cascading decks painted in different shades of blue evoke the waves of the sea, create an effect that tricks the eye into perceiving a far leaner silhouette than the vessel truly possesses. At the time of her delivery, she contained more marble and stone in her interior than any other superyacht ever recorded.

Following purchase, Walton Laurie, daughter of Walmart co-founder James “Bud” Walton and one of the world’s wealthiest women with a fortune estimated at around $10 billion, undertook a major refit in Hamburg. Over 1,500 square metres of interior spaces were redesigned, and the yacht was rechristened Kaos.

Meet Kalm, the vessel travelling in convoy

Accompanying Kaos on her Puerto Banus visit is Kalm, a 67-metre support vehicle valued at around $30 million. Carrying helicopters, tenders, jet skis, and all technical equipment required for operations at sea, Kalm ensures Kaos keeps its guest spaces completely uncluttered

Environmental scrutiny and a brush with eco-activists

Kaos has not always sailed in calm waters. Back in July 2023,she was targeted by eco-activists , defacing her hull with red and black spray paint in protest at the environmental impact of superyacht travel. During a previous stay in Spanish waters, Euro Weekly News reported on the massive strain the vessel placed on local infrastructure, revealing how the €300m superyacht drained immense amounts of electricity and shore power simply to keep its internal systems running while sitting idle at the dock in Malaga.

Puerto Banus still a magnet for the global elite

Every summer, the world’s most exclusive superyachts choose the famous port as one of their stops through Europe. Few destinations can match Marbella’s combination of glamour, infrastructure, and climate.

As temperatures begin to soar across Spain, pet owners are being urged to take extra precautions when exercising their dogs. Under Spain’s Animal Welfare Law, owners have a legal responsibility to protect animals from conditions that could cause suffering or injury, with serious breaches carrying fines of up to €50,000.

The warning comes as veterinarians continue to highlight the dangers of heatstroke, dehydration and burns caused by hot pavements during the summer months. While many residents adjust their routines during periods of extreme heat, experts warn that dogs remain particularly vulnerable because they are less able to regulate their body temperature than humans.

Legal responsibility and potential penalties

Authorities may consider it a breach of an owner’s duty of care if a dog suffers harm as a result of being exposed to dangerous conditions, particularly if the animal develops heatstroke, dehydration or injuries caused by hot surfaces.

Under Spain’s animal welfare framework, serious infringements can carry fines ranging from €10,001 to €50,000. The severity of any penalty depends on the circumstances and the impact on the animal’s wellbeing.

Why hot weather can be dangerous for dogs

Unlike humans, dogs do not cool themselves efficiently through sweating. Instead, they primarily rely on panting and limited sweating through their paw pads.

During periods of extreme heat, dogs can quickly become overheated, especially when exercising, walking on hot surfaces or spending prolonged periods in direct sunlight. Certain breeds, including Bulldogs, Pugs and French Bulldogs, are particularly vulnerable because their shortened airways make cooling themselves more difficult.

Owners should also ensure that any muzzle used does not prevent panting, as this can increase the risk of overheating, particularly during hot weather.

Older dogs, puppies and animals with underlying health conditions also face an increased risk of heat-related illness. Heatstroke can develop rapidly, particularly during Spain’s summer heatwaves, making prevention essential.

How to keep your dog cool during Spain’s summer

Veterinary experts recommend walking dogs during the coolest parts of the day, ideally early in the morning or later in the evening when temperatures are lower. Strenuous exercise should be avoided during the hottest hours, typically between midday and late afternoon.

Owners should always carry fresh drinking water and offer it regularly during walks. Access to shade is equally important, particularly in urban areas where concrete and asphalt can reach extremely high temperatures.

A simple way to test whether the ground is too hot is to place the back of your hand on the pavement for several seconds. If it feels uncomfortable, it may also be hot enough to burn a dog’s paw pads.

At home, pets should have constant access to fresh water, shaded areas and adequate ventilation. Cooling mats, fans and damp towels can help reduce heat stress, while dogs should never be left unattended inside parked vehicles, where temperatures can rise to dangerous levels within minutes.

Recognising the signs of heatstroke

Heatstroke is a veterinary emergency that requires immediate attention. Early warning signs often include excessive panting, heavy drooling, restlessness and difficulty settling.

As the condition worsens, dogs may become anxious, weak, lethargic or disoriented. Other symptoms can include bright red gums or tongue, rapid breathing, vomiting, diarrhoea, excessive salivation, loss of coordination, collapse or unconsciousness.

Without prompt treatment, heatstroke can lead to organ failure and may prove fatal. For this reason, pet owners should act quickly if they suspect their dog is overheating.

What to do if you suspect heatstroke

If a dog begins showing signs of heatstroke, it should be moved immediately to a shaded or cool location. Small amounts of cool drinking water can be offered, but the animal should not be forced to drink.

Owners should begin lowering the dog’s temperature gradually using cool, rather than ice-cold, water. Wet towels can be applied to the neck, chest and abdomen to help reduce body temperature safely.

Veterinary attention should be sought as soon as possible, even if the dog appears to recover. Internal complications can develop after the initial symptoms have subsided and may not be immediately visible.

Questions and answers

Is it illegal to walk a dog in hot weather in Spain?

No. Spanish animal welfare law does not set a specific temperature at which walking a dog becomes illegal, including 40°C or above.

However, the law does require owners to avoid exposing animals to conditions that could cause suffering or injury. In extreme heat, this can include risks such as heatstroke, burns from hot asphalt, dehydration or collapse from overheating.

Whether an offence has occurred depends on the circumstances, including the time of day, duration of the walk, condition of the dog and whether reasonable precautions were taken.

Can someone really be fined €50,000?

Potentially, yes. Serious infringements under Spain’s Animal Welfare Law can carry fines of between €10,001 and €50,000 where negligence results in significant harm to an animal.

What is the safest time to walk a dog during summer?

Early morning and late evening are generally the safest times, when temperatures are lower and pavements are less likely to cause burns.

How can owners tell if the pavement is too hot?

A common guideline is to place the back of your hand on the surface for several seconds. If it feels uncomfortably hot, it may also be too hot for a dog’s paws.

What is the biggest danger during extreme heat?

Heatstroke is one of the most serious risks. It can develop rapidly and requires immediate action and veterinary treatment.

A reminder for pet owners

As Spain enters another summer of high temperatures, veterinarians and animal welfare organisations continue to stress the importance of prevention. While the law does not specifically ban dog walks during hot weather, owners are expected to act responsibly and avoid exposing animals to conditions that could jeopardise their health.

By adjusting walking times, providing plenty of water and recognising the signs of heatstroke, residents can help ensure their pets remain safe throughout the hottest months of the year while complying with their responsibilities under Spanish law.

As the weather warms across Spain, rising sea temperatures and shifting coastal currents create conditions that affect what swimmers experience in the sea. In recent years, lifeguards in some coastal areas have reported more frequent encounters at water level, particularly during busy beach periods on the Mediterranean coast.

However, what beachgoers perceive as “jellyfish season” is often less about visible swarms and more about unpredictable in-water encounters, where swimmers come into contact with organisms they did not see beforehand.

Seasonal presence along Spanish coasts

In Spanish waters, jellyfish-related encounters are often patchy and localised rather than widespread. One beach may have clear water while another just a few kilometres away experiences brief concentrations carried in by currents.

This variability means swimmers are often reacting to conditions at a specific moment in a specific stretch of water, rather than a uniform presence along the coastline.

What swimmers actually encounter in the water

What people describe as “jellyfish in the sea” is often a mix of different floating organisms, fragments, and natural debris rather than clearly identifiable animals.

Common real-world encounters include:

• translucent fragments drifting just under the surface 
• small blue sail-like organisms such as By-the-wind Sailor (Velella velella)
• detached tentacle strands invisible until contact 
• seaweed or jelly-like plankton clusters 

This is why swimmers can be stung even when nothing obvious is visible, the hazard is often microscopic or fragmented rather than fully formed animals.

Which jellyfish-related encounters are most noticeable

From a swimmer’s perspective, the worse encounters are not necessarily the most dangerous species, but the ones that create immediate sensation in the water.

The mauve stinger (Pelagia noctiluca) is often associated with sharp, immediate skin contact, which makes it more noticeable even in short encounters.

The Portuguese man o’ war (Physalia physalis) tends to be reported differently, often because swimmers describe a burning contact followed by lingering pain, even from brief exposure.

By contrast, many other jellyfish-like organisms may be present in the water without being noticed at all, due to weak or absent sting effects.

What type of waters increase the chance of encounters

Rather than being tied to fixed locations, jellyfish encounters are strongly linked to how water is moving at a given time.

Key factors include:

• water movement patterns, which can concentrate organisms in narrow coastal bands 
• surface drift conditions, where floating life accumulates in specific zones 
• temperature layering in the sea, which can affect where organisms sit in the water column 
• short-term wind shifts, which can rapidly change beach conditions within hours 

This means two swimmers in the same region can have completely different experiences depending on timing and exact location.

In some cases, combinations of these conditions can lead to short-lived increases in encounters, but they are typically temporary and highly localised rather than sustained trends across entire coastlines.

How to tell if jellyfish are in the sea

Detection is often less about seeing jellyfish clearly and more about recognising indirect signals in the water environment.

These include:

• sudden clusters of floating organic matter 
• changes in how swimmers feel in shallow water 
• small translucent shapes near wave breaks 
• warnings from lifeguards based on current drift patterns 

In many cases, swimmers only become aware of presence after first contact.

What happens when you are stung

A sting occurs when skin comes into contact with microscopic stinging structures embedded in tentacles or fragments. These structures are designed to activate on touch rather than sight.

Reactions vary depending on exposure level and sensitivity, and may include:

• sharp or burning sensation on contact 
• localised redness or irritation 
• raised skin response 
• short-term swelling in affected areas 

In most cases, the reaction remains localised and temporary.

What happens in the first moments after a sting

When jellyfish contact occurs, most people do not immediately realise what has happened and panic can set in. The first sensation is often a sudden burning or stinging feeling on the skin, which can intensify within seconds depending on the species and level of exposure. In many cases the reaction is influenced not just by the sting itself, but by what is still present in the water or on the skin after contact.

Tiny fragments of tentacle material or stinging structures can continue to activate even after the initial encounter, which is why discomfort may persist or spread slightly beyond the original point of contact, for that reason its recommended to slowly make your way out of the water and do not thrash around as you can risk more stings

The severity of the reaction varies widely between individuals and species, but most incidents remain localised to the skin and short-lived. More pronounced reactions tend to be associated with higher exposure or more reactive species, particularly in warmer, sheltered coastal waters where encounters are more concentrated.

In situations where symptoms escalate beyond mild skin irritation or do not begin to settle naturally over time, medical assessment is used as a precautionary measure in coastal areas.

When to seek medical help

Medical support is generally only required when reactions extend beyond mild skin irritation or when symptoms escalate unexpectedly.

This includes:

• large affected areas 
• persistent or worsening pain 
• systemic symptoms such as dizziness or breathing difficulty 
• vulnerable individuals such as children or elderly swimmers 

Emergency services in Spain operate via 112, with lifeguards often providing the first point of response on beaches.

Prevention and beach safety

Rather than relying on visible detection alone, swimmers are encouraged to pay attention to real-time beach conditions, jellyfish trackers and water behaviour, as jellyfish-related encounters are often not visually predictable.

Even when conditions appear clear, contact can still occur due to fragmented material or drifting organisms not visible at surface level. Awareness of water movement and local warnings remains the most effective way to reduce unexpected encounters.
