How alcohol affects your body and surfing

Alcohol and surfing: not the best match | Photo: McEwen/Creative Commons

Surfing has always carried a laid-back image. Sun, saltwater, and long afternoons often blend into social time afterward.

In many places, that includes alcohol.

The connection is old, visible, and sometimes romanticized by cool, chilled commercials of light Mexican beer and sunset sessions in idyllic conditions.

But the effects of alcohol on the body, and on surfing performance, are far less relaxed.

"The surf world's relationship to alcohol isn't much different from that of other sporting or recreational cultures," surf historian Matt Warshaw wrote on his "alcohol and surfing" entry on "The Encyclopedia of Surfing."

So, for most surfers, cracking a single cold beer really is the perfect ritual to end a session.

"I'm a two-beer guy," Kelly Slater once revealed.

And while this picture might apply to the majority of surfers, for some, it's something else entirely.

A long history of beer, surfboards, and beach culture

Alcohol has been part of surf culture for decades, both socially and commercially.

Warshaw points out how deeply the two have been linked through events and sponsorships. Beer and liquor brands have backed competitions and athletes for years, tying wave riding to nightlife and celebration.

Foster's, Budweiser, Smirnoff, Corona, Jose Cuervo Tequila, Bundaberg Rum, Kahlua, Coors, Coopers, Michelob, Primo Beer, and Kona Big Wave are only a few examples of beer and liquor brands that financially supported the professional surfing circuit in the ASP and WSL years.

The stories involving surfers and alcohol can be lighthearted. Warshaw includes a moment from Kevin Naughton, who wrote:

"We thought that our last pints were being pulled at 11:30... At three in the morning, I just managed to squeeze my way through the chattering, musical crowd, and nonchalantly asked the barman, 'When does the pub close?' He answered with a deadpan voice, 'In October.'"

The humorous moment is just that. Because within surf culture, like society, athletes often struggle to separate casual drinking from harmful habits.

What alcohol does to the body

Now, let's just stick to pure facts.

Alcohol affects nearly every system in the body. Even moderate amounts can impair coordination, reaction time, and judgment.

We'd probably agree that these are key skills for surfing.

You might say that a single beer does more good than harm if you're socializing and having a good time with friends.

It's an understandable argument, even though it is a subject of intense debate.

However, if you're planning to paddle out immediately after, here's what's at stake based on consistent scientific findings:

  • Blood alcohol concentration (BAC) as low as 0.03 percent can reduce reaction time and visual tracking;
  • At 0.05 percent, coordination and decision-making are measurably impaired;
  • At 0.08 percent, which is the legal driving limit in many countries, balance, muscle control, and spatial awareness are significantly reduced;

Surfing depends on fast reflexes. A surfer reads waves, adjusts stance, and reacts in fractions of a second. Alcohol slows these processes.

Obviously, a beer, here and there, especially after a session, could be seen as marginally irrelevant.

But here are the stronger effects of long-term excessive drinking:

  • Reduced muscle recovery and strength;
  • Dehydration, which affects endurance;
  • Liver damage, which impacts energy metabolism;
  • Brain changes that affect memory and motor skills;

All these impacts and consequences build over time and do not stay on land when a surfer enters the water.

The immediate risks of surfing drunk

We all know how unpredictable the ocean can be. Now, adding alcohol increases risk sharply.

A surfer under the influence may misjudge wave size and power, react too slowly to avoid collisions, lose balance more easily, and underestimate currents or rip tides.

Interestingly, cold water makes things worse.

Why? Alcohol causes blood vessels to expand, which increases heat loss. A surfer will feel warm at first but will then lose body heat faster, raising the risk of hypothermia.

Drowning risk also rises.

Studies on water safety show that alcohol is involved in a significant percentage of drowning incidents worldwide.

And it's quite easy to understand why: impaired judgment leads to poor decisions, and slower reactions make recovery harder.

The impacts described above apply to surfers of all levels, including experienced riders. No one is immune, and alcohol surely reduces the margin for error.

Performance levels over time

In the competitive circus, we often hear that surfing rewards consistency and that balance, timing, and endurance improve with practice and physical health.

The thing is, regular heavy drinking works against all of these.

Athletic research shows that chronic alcohol use can lower aerobic capacity, reduce coordination and fine motor control, disrupt sleep (which affects recovery), and increase body fat and reduce lean muscle.

One anonymous surfer quoted in Warshaw's magnum opus shares a very personal perspective on heavy drinking.

"So, Matt Hoy is a hot surfer who drinks heaps of beer? Big deal! So was I, and now I am a fat, bloated, red-faced has-been with nothing to look forward to in life."

It's the perfect statement that reflects a real-life pattern. Over time, heavy drinking can erode the physical edge needed to surf at the highest, or even average, level.

Aging, booze, and the surfing body

As surfers get older, their bodies change naturally. Muscle mass declines, reaction time slows, and recovery takes longer.

Alcohol only accelerates many of these natural aging effects - just like smoking. On top of that, older adults process alcohol more slowly.

The general consequences are clear: stronger impairment from smaller amounts of booze, greater strain on the liver and heart, and increased risk of falls and injuries.

For surfers, it will mean slower pop-ups, reduced balance on the surfboard, and a higher risk of injury during wipeouts.

It's hard not to get back to Matt Warshaw when he notes that surfers are often "health conscious, mildly optimistic, and forward-looking."

These are all traits that can help limit harmful habits, especially those involving ethanol-based drinks.

But when heavy drinking continues into later years, the gap between intention and reality will grow.

What the World Health Organization says

Alcohol's health risks are well established, and global health experts now agree there is no completely safe level of consumption.

The World Health Organization (WHO) states that alcohol itself is a harmful substance. It is toxic, addictive, and classified as a Group 1 carcinogen, meaning it is proven to cause cancer.

It includes common cancers such as breast and bowel cancer, and the risk applies to all alcoholic drinks, regardless of type or quality.

Even low or moderate drinking carries risk.

In Europe, about half of alcohol-related cancers are linked to what many consider a moderate intake. Scientists also stress that harm begins with the first drink.

"We cannot talk about a so-called safe level of alcohol use… the risk to the drinker's health starts from the first drop," explained Dr. Carina Ferreira-Borges, acting Unit Lead for Noncommunicable Disease Management and Regional Advisor for Alcohol and Illicit Drugs in the WHO Regional Office for Europe.

Claims of health benefits from light drinking remain uncertain, with Dr. Jürgen Rehm, member of the WHO Regional Director for Europe's Advisory Council for Noncommunicable Diseases, noting they often depend on study methods and may overlook key factors.

Alcohol continues to be a major public health issue, especially in Europe, where consumption levels are high.

Experts warn that focusing on "safe" levels can distract from the bigger picture of harm and the need for better public awareness about the link between alcohol and cancer.

A culture that reflects a larger reality

Surfing does not exist in isolation. Its relationship with alcohol mirrors the wider world. Social drinking is common and often harmless. Problem drinking is less visible but more damaging.

Warshaw writes that surf culture "reflects the culture at large in the way it chooses not to deal with the ambivalence between approved, or glorified, drinking and problem drinking."

That tension is still present today.

For many surfers, a cold beer after a session is part of the ritual. The key difference lies in frequency, quantity, and awareness of risk.

In the water, the stakes are immediate. Over time, the effects become harder to ignore.

Time to make your choices.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history.

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
