It’s back, like a cold sore. Nazaré Canyon.
The wave that sometimes isn’t a wave because a wave has a
crest and a trough, and Nazaré often lacks the latter.
The hype that
comes with it is back too.
“Biggest wave ever ridden?”
“The 100-foot
wave?”
“I’m Ron Burgandy?”
Those question marks express doubt, and
rightfully so.
It’s like a surfers version of a cheap philosophical
question: If a wave breaks without a bottom, does it break a world
record?
It stirs up a bigger question of how we measure waves, and the
inevitable pitfalls flaws we run into in the process.
A wave is measured
as the vertical distance between the crest and the trough.
Find the
bottom.
Find the top.
Measure the distance.
Should be easy.
But when you’re looking at a wave straight on, especially from elevation, things can get tricky.

Nazaré Canyon is a caricature of this phenomena .
At steep waves like
Jaws or Maverick’s you can see that the lip is almost directly above
the trough (or at least is in the frame).
But at Nazaré, because the
wave is so flat, the distance between the lip and the bottom of the wave
might be a 100 feet long, while the wave height is actually more around
60 feet

"It developed S/SSW of Greenland on October 25th," explained Surfline's Mike Watson.
"And this system maintained its intensity as it tracked east the next day, which resulted in a captured fetch -- maximizing swell generation for Europe. A cold front associated with it approached the region early on Monday, which allowed for window of good conditions for spots that prefer south wind."

See the above example of Carlos Burle’s wave at Nazaré on
October 28.
At first glance it’s the biggest wave ever ridden (or at
least as big as either of Garrett’s from the same wave and same camera
angle).
The wave looks 100 feet because we’re seeing about 100 feet of
face in the image, but that face isn’t vertical.
Far from it.
This is
shown in the following graph, which illustrates a virtual cross cut of
this wave.
When looking at waves from the side, like Alain Riou’s wave at
Belharra below, you can easily draw a vertical line from the bottom of
the wave to meet a horizontal line drawn from the crest of the wave and
measure the height that way.
But that becomes impossible when you’re
looking at a wave photographed from the front, because even if you found
the bottom of the wave (a subjective location in most photographs), you
can’t draw the horizontal line from the crest of the wave toward the
bottom because you’d be entering a third dimension that a 2D photograph
doesn’t allow.
What lessons can we take away?
- Nazaré is a place where giant swells are ridden, but these aren’t 100-foot waves.
- The wave is dangerous, as we saw with Maya Gabeira’s broken ankle-to near drowning-combo.
- We need a better way to measure waves, especially when they’re photographed from the front. If anyone is knows of any special technology, software or math that is available that might help with something like this, we’d love to hear about it.
