Cold Water, Clear Ears: The Sea Swimmer’s Guide to Avoiding Surfer’s Ear

Surfer’s ear sounds like something mythical, but it’s really your body doing a very practical thing: building little bony shields inside the ear canal in response to repeated cold wind and water. Great for ancient sea survival… less great for modern hearing.

You don’t need to give up sea swims. You just need to outsmart the elements a bit.

The core idea: keep cold water + wind out of your ears

1) Wear proper earplugs (this is the big one)

Not all earplugs are equal:

• Vented surf earplugs (best all-round):

   Let sound in but keep water out. You can still hear waves, people, and your own breathing.

  Brands like SurfEars are popular.

  
  

• Mouldable silicone plugs (budget, effective):

  Great seal, but you’ll feel more “underwater” acoustically.

  
  

• Custom-fitted plugs (gold standard):

  Made from impressions of your ears. Expensive, but extremely comfortable and secure.

  
  

If you do one thing, do this. It’s the single most effective prevention.

2) Add a neoprene hood or ear band

Think of this as your ears’ winter coat:

• Keeps cold wind off your ears

• Adds a second barrier to water

• Especially useful in UK waters where “bracing” is an understatement

Even a simple neoprene ear band can make a noticeable difference.

3) Limit exposure to cold + wind combo

Cold water alone isn’t the full villain. It’s the tag-team of:

• Cold water +

• Cold wind (especially after you get out)

So:

• Dry your ears and cover your head quickly after swims

• Avoid standing around chatting with wet ears in a breeze (tempting, I know)

  
  

4) Warm-water rinses after swimming

A gentle rinse with warm (not hot) fresh water can help clear salt and cold residue.

Some swimmers use acidic ear drops (like alcohol/vinegar mixes), but:

• They’re more for infection prevention than surfer’s ear itself

• Skip if your ears are sensitive or irritated

5) Be consistent (this is where most people slip)

Surfer’s ear develops slowly, like tree rings. One unprotected swim won’t do it… but habits will.

If you’re a regular sea swimmer around places like English Channel, consistency matters more than intensity.

Early signs to watch for

• Water getting trapped more easily

• Slight hearing dullness after swims

• Frequent ear infections

If that starts happening, it’s worth seeing a GP or ENT specialist early. Advanced cases sometimes need surgery, which is… not the kind of souvenir most swimmers want.

Simple “ritual” to remember

Before swim:👉 Earplugs in → Hood on

After swim:👉 Dry ears → Cover head → Warm up

Solid earplug options you can actually get in the UK

Vented earplugs (best all-rounders)

These are the sweet spot for sea swimmers.

• SurfEars (v3.0)

   The gold standard. You can hear clearly, they stay put in waves, and they come with different size tips.

   ~£45–£60

  Best if you swim regularly and want zero fuss.

  
  

• Alpine SwimSafe

  Slightly cheaper, still vented, decent comfort.

  ~£15–£20

  Good mid-range option.

  
  

• Doc's Proplugs

   A bit more “old-school” surfer vibe. Not as refined for hearing, but very effective at blocking water.

  ~£15–£25

Mouldable silicone (budget + simple)

• Mack's Pillow Soft Silicone

  You roll them into a little seal over your ear canal.

  ~£5–£10

  
  

• Speedo Biofuse (silicone type)

  Slightly more structured but still comfy.

  
  

  Downsides: sound gets muffled, and they can occasionally drift loose in choppier water.

The simple framework for our group

• Dippers (occasional head-under) → keep it easy, low-cost, low-faff

• Regular head-under swimmers → proper protection, consistent habit

• Cold-sensitive or frequent swimmers → double layer (plugs + neoprene)
