What’s the difference between Swimmer’s Ear and Surfer’s Ear?

Most people miss this one on the first try; and honestly, how can we prevent something we don’t fully understand?

As a swimmer, surfer, and kinesiologist, I love digging into this topic with the water-loving community. Let’s clear the confusion and break it down, one ear at a time.

Swimmer’s Ear

Swimmer’s Ear is a bacterial infection caused when water; especially from lakes, oceans, or dirty pools, gets trapped in the ear canal. That warm, damp environment becomes the perfect breeding ground for bacteria.

It’s one of the big reasons we always say: avoid swimming in brown water after heavy rains, and make sure pools are properly maintained.

The good news? Swimmer’s ear is typically treated with prescription ear drops and clears up quickly with proper care.

Surfer’s Ear

Surfer’s Ear is a fascinating bodily adaptation; our ear’s way of shielding itself from the elements. Over time, bone begins to grow in the ear canal, forming spiral-like layers (think mushrooms winding around a tree trunk) to block out salt, sand, and wind.

It used to be linked mostly to cold water surfing, but now we know warm water surfers are also at risk; especially since we tend to stay in the water longer. The longer you surf, the higher your chances: risk creeps up little by little with each passing year.

If the bony growth becomes too severe, it can block the canal entirely and may require surgical removal. That’s why prevention matters.

Personal Story

I’ve worn SurfEars since 2016, after my right ear; already vulnerable, started hurting from surfing five days a week. These buds let sound in while keeping water out, and they’ve helped me stay in the water without pain or further damage.

A couple of times, people have even paddled over thinking I’m listening to music! Keep an eye out; we’ll be stocking SurfEars on our website and locally here on Maui. I originally found mine at a Westside dive shop, and since it closed, finding quality ear protection has been surprisingly tricky.

Ironically, the hardest gear to track down on island? Solid ear plugs, and a waterproof watch that isn’t an Apple Watch.

If you surf often, ear protection isn’t just helpful; it’s essential. SurfEars can help prevent bone growth, surgery, and long-term hearing issues.
