Myth of the collapsing sand bar

Every time I give one of my Science of the Surf community talks I always get asked the same question “Do sand bars collapse?” and I always give the same answer “No, sand bars do not collapse unless you blow them up with explosives”.

Sand bars are big piles of sand that are pretty solid and heavy. Sure, they shift around from time to time, but this takes days, weeks and even months. They never, ever, ever implode on themselves. It just doesn’t happen.

But you still hear stories of collapsing sand bars getting people into all sorts of strife. So where did this myth come from? Well, if it’s wacky and related to the beach, it must come from… Bondi.

How to prevent sea-sickness when ocean swimming

Over the years I’ve had a handful of OceanFit participants who’ve suffered from sea-sickness when swimming in the ocean – and it doesn’t sound good!

Some of them first realise it will be a problem while participating in one of our clinics (when we bob up and down out behind the waves learning ocean swimming techniques), others get a rude shock when taking on their first ocean swim.

What to look for in an open water swimming wetsuit

Are you thinking about purchasing a wetsuit for open water swimming, or ocean swimming?

As an ocean swimming instructor I spend a lot of time in the water… a lot!

Sometimes the water is warm, other times it’s freezing (see Coriolis effect: when the water gets cold in the summer), but one thing remains true, just being in the water for a long time can quickly drop your core temperature.

So, whether I’m coaching, or ocean swimming, if I’m wearing a wetsuit I want to be wearing one that’s comfortable, flexible and that will give me an edge.
