When we talk about the biggest wave in the world, we immediately think of Nazaré. Tiny surfers facing the ocean in extreme conditions. But not all big waves are the same—there are dozens of them, and the notion of “size” deserves to be nuanced.
Some waves impress with their towering height, while others stand out for their length, offering endless rides. So, what is the biggest wave in the world? Where are these water monsters located, and why do they exist?
The formation of the biggest waves in the world
These gigantic waves are not the result of chance. They form through the combination of several very specific natural factors. And it is the complexity of bringing all these factors together that makes them so rare.
The power of the swell
Big waves are generated by powerful ocean storms located thousands of kilometers from our shores. The stronger the wind blows, the longer it blows, and the greater the distance it covers, the more energy the swell builds up.
Swell energy is measured in kilojoules. But in surfing, we are more concerned with swell height (meters), period (seconds), and direction.
The bathymetry of the seabed
The shape of the seabed plays a decisive role. Submarine canyons, steep reefs, or rocky shelves concentrate the energy of the swell, causing these waves to rise abruptly.
A rapid change in depth increases the size of the wave. The more sudden the transition, the more violently the wave stands up. It is often this factor that turns a regular swell into a massive wave.
The orientation of the spot
A spot perfectly exposed to the prevailing swell receives the full force of its energy. Conversely, an unfavorable orientation can cancel out any potential, even with a powerful swell.
Can we really talk about a single biggest wave in the world?
The question often comes up: what is the biggest wave in the world?
In reality, it all depends on how we define size.
- In height: some waves exceed 30 meters.
- In length: others offer rides of several hundred meters.
That’s why we can distinguish between two categories:
- the biggest waves (in height).
- the longest waves (in distance).
The biggest waves in the world (by height)
Nazaré (Portugal) – The biggest wave ever surfed in the world
Nazaré is now the absolute benchmark when talking about the biggest wave in the world. Located on the Portuguese coast, this spot is famous for its submarine canyon stretching over 200 km, one of the deepest in Europe.
This canyon acts as a natural amplifier:
- It concentrates the energy of the swell
- It causes a sudden rise in the wave
- It generates waves that can exceed 30 meters
Combined with perfect exposure to massive Atlantic swells, Nazaré holds several world records and is regularly cited as the biggest wave ever surfed in the world. It is also the biggest wave in Europe.
Jaws (Hawaï)
Located on the island of Maui in Hawaii, Jaws is one of the most feared spots on the planet. Here, the wave is not only tall, it is also extremely hollow.
- Massive Pacific swell
- Very committed take-off
- Thick and powerful waves
Jaws is often presented as the biggest wave rideable by paddling. Nazaré becomes impossible to paddle into beyond a certain size (jet ski assistance then becomes essential).
Mullaghmore Head (Ireland)
Located on the west coast of Ireland, “Mully” for those in the know takes the full force of the most powerful North Atlantic swells. It’s a unique wave:
- Unpredictable slab (very shallow rocky bottom)
- Freezing water (never more than 8–10 degrees in winter)
- Steps and bumps in the wave face
Mullaghmore Head is considered by many big wave surfers to be the wildest wave. A rocky bottom that doesn’t forgive the slightest mistake. Being in the water requires total commitment.

Mavericks (California)
Mavericks, located off the coast of California, is a legendary big wave surfing spot with extreme conditions.
- Cold, very deep water, sharks
- Strong current
- Nearby rocks
The waves can exceed 20 meters and are known to be among the most dangerous in the world.
Teahupo’o (Tahiti)
Teahupo’o is not the tallest wave, but it is probably the most impressive wave in the world.
- Very hollow wave
- Huge water mass
- Extremely shallow reef
Its danger, power, and shape make it a regular contender for the title of biggest wave in the world.
The longest waves in the world (by distance)
Some waves, meanwhile, stand out for their exceptional length. And also because they are a little more accessible to the average surfer…
Mundaka (Spain) – The longest wave in Europe
Located in the Spanish Basque Country, Mundaka is globally recognized as the longest wave in Europe and one of the longest left-handers in the world.
- Barreling wave
- Rides that can exceed 300 meters
- Huge crowds in the water
Chicama (Peru)
Chicama also deserves its place among the TOP longest waves in the world.
- Legendary long left-hander
- Rides that can last more than 2 minutes
- Accessible spot but very demanding
It attracts surfers from all over the world for its quality and accessibility, but Chicama is a wave that can be fast and technical.
Jeffrey’s Bay (South Africa)
Jeffrey’s Bay is considered by many to be the best wave in the world. It offers perfect right-handers with barreling sections and maneuver sections. It is a regular-footers’ paradise.
- A succession of perfect sections
- The possibility to barrel and perform maneuvers on the same wave
- Sharks
Jeffrey’s Bay is mainly reserved for expert surfers as it is highly technical.
Skeleton Bay (Namibia)
Every surfer has inevitably seen a GoPro video of the wave at Skeleton Bay. It is a legendary and ultra-photogenic wave because of its speed, shape, and length.
- Ultra-long left-hander
- Endless but highly technical barrels
- Rare and very fickle wave
It is one of the most spectacular waves in the world.
So, what is the biggest wave in the world?
The biggest wave in the world cannot be reduced to a single number. It is the result of a balance between height, power, shape, and length.
