The crowds arrive long before the tide turns.
On a warm day at Westward Ho!, families drag windbreaks across the sand while surfers stand at the water's edge studying the swell. Children race towards the shoreline with buckets and spades, barely glancing at the sea beyond. It looks inviting, almost gentle.
Matt Whitley knows better.
After more than 20 years as a lifeguard, and now as lead lifeguard supervisor for North Devon and Somerset, he has spent much of his working life watching the water and, perhaps more importantly, watching the people drawn to it.
This year marks 25 years since the RNLI began running lifeguard services around Britain's coastline. For Matt, the anniversary is a chance to reflect not only on how the organisation has evolved, but on how the public's relationship with the sea has changed too.
Speaking after a busy half-term period blessed with sunshine and strong surf, he admits it has been a memorable start to the season.
"We've just had a really good half-term week," he says. "It's been amazing weather, it's been good surf, it's been really good for us locally and really good on our beaches."
Yet his thoughts quickly turn to more sobering matters.
The sunshine has arrived against a backdrop of several tragic incidents nationally, a reminder that no matter how beautiful the sea may appear, it remains unpredictable and unforgiving.
"It's really poignant that we're here today to discuss things," he says.
The RNLI's lifeguard operation may now be a familiar sight on beaches around the country, but its beginnings were surprisingly modest.
"This year is 25 years of the RNLI running lifeguard services across the country," Matt explains. "It started in 2001 in a few trial areas."
Over the years, the service has expanded dramatically, becoming a professional operation backed by training, specialist equipment, operational support and national expertise.
"For a quarter of a century now, the RNLI has been running a lot of lifeguard services and how that's really professionalised the service nationally and what it's done for lifeguarding and keeping beaches safe in general."
Locally, that work centres on beaches including Westward Ho! and Sandymere, where lifeguards patrol daily throughout the summer season.
What beachgoers see, however, is only a fraction of the operation.
Before a lifeguard ever sets foot on the sand, they will already have completed extensive training covering casualty care, rescue techniques, communications, incident management and emergency response.
Matt is particularly proud that many of those lifeguards come from the communities they serve.
"We have a completely local team," he says. "We work through the lifesaving clubs, we advertise locally and we've got a real local team that know the beaches and know the community."
That local knowledge matters.
Ask Matt what has changed most during his two decades on the coast and his answer comes quickly.
"The biggest change is the change in use of the coastline.
"Cold-water swimming and paddleboards are on the rise and it's a really amazing thing to see that our coastline's being used by the community a lot."
The challenge is ensuring those people understand the risks that come with it.
"The local communities are really the ones that know the dangers," he says. "They know about the tides, they know about the bars, the rips and everything else."
It is often visitors, rather than locals, who concern him most.
"It's really where a lot of the work the RNLI is trying to do - how can we reach communities where they don't even know what a tide is?"
He laughs as he recalls some of the conversations he has had over the years.
"You have had people say, 'Last year I came here and it was all the way out there. What's happened? Is it global warming?'"
The humour is gentle, but the message is serious.
Many of the people arriving on Britain's beaches have never encountered tidal waters before. They do not understand rip currents. They do not know how quickly conditions can change. Some simply do not realise the power of the sea.
For Matt, that is where the real work of lifeguarding begins.
The public often focuses on rescues, and understandably so. Last year alone, RNLI lifeguards at Westward Ho! and Sandymere responded to 115 incidents involving 129 people. There were 18 rescues, 19 major first aid incidents and dozens of other call-outs.
Yet those are not the figures that matter most to him.
"The figure I'm really proud of is the 14,000 preventative actions."
More than half involved face-to-face conversations with beachgoers. Others included public announcements, safety advice, flag placement and warning signs.
"When we're looking at the pyramid of somebody unfortunately possibly losing their life in the sea, we're really interested in that bottom figure and how much we can do there."
In other words, the aim is not simply to rescue people.
It is to stop them needing rescue in the first place.
Those conversations happen thousands of times every summer. Most pass unnoticed by the public. A quiet word here. A warning there. Advice about a rip current, an incoming tide or a safer place to swim.
Taken individually, they seem insignificant.
Taken together, they may be the most important work lifeguards do.
"It's the same thing, isn't it?" Matt says when asked about the biggest challenges facing the service today.
"The sea's one of those dangerous things and we're just trying to educate people."
After more than 20 years on the coast, his answer remains refreshingly simple.
"I think there is a raised awareness of the sea now. There's a raised awareness of going out. But there's also just more people using it."
That popularity brings challenges beyond the traditional summer season.
Cold-water swimming has exploded in recent years, with many enthusiasts entering the water throughout the winter months, often in conditions far removed from the busy beaches of July and August.
Recent tragedies have prompted renewed discussion about how councils, emergency services and coastal organisations can encourage safer behaviour.
"There is a lot that is already going on," Matt says.
He points to education programmes, school visits, community engagement projects and awareness campaigns that are already helping spread vital safety messages.
Each year, RNLI teams visit schools across North Devon and Torridge, speaking to thousands of children about water safety before the summer holidays begin.
Volunteers carry out lifejacket clinics, attend community events and support wider public awareness campaigns.
"It's just raising the awareness and education, I think, and pointing people in the right direction of how they can enjoy the sea safely."
The challenge, he believes, is not always producing information.
It is making sure the right people hear it.
"You can put signs out and it's great. It's one of the things you should have. But it's whether people read those signs."
The same challenge exists beyond the coastline itself.
Recent national figures have highlighted the dangers posed by rivers, lakes and reservoirs, particularly during periods of hot weather.
For Matt, understanding why people take risks is as important as understanding the water.
"When it's hot, people want to cool down," he says with a shrug.
It is a simple observation, but one that cuts to the heart of modern water safety.
People will always be drawn to water. They will always seek adventure, exercise, excitement and escape.
The task facing organisations such as the RNLI is not to stop them.
"We can't sometimes stop people," Matt says. "But we can educate them on the risk and how they can manage the risk themselves."
As the RNLI celebrates 25 years of lifeguarding, that philosophy feels as relevant as ever.
The public may remember the dramatic rescues. The flashing lights, the lifeboats and the headlines.
Matt thinks instead about the conversations.
The family persuaded to move between the flags. The paddleboarder advised about changing conditions. The swimmer warned about a rip current before entering the water.
Thousands of moments that never become incidents.
Thousands of interventions that never make the statistics.
And, perhaps, thousands of lives quietly steered away from danger before they ever realised they were at risk.
