Why you shouldn’t swim after it’s rained

Ever hear the warning ‘don’t swim after it’s rained’?

That’s because the rain runs off our paved streets directly to the ocean via the network of stormwater drains, canals and rivers every city has, carrying with it all the nasties accumulated along the way. Then there’s the periods of heavy rain… when water management authorities may decide to ‘bypass’ the sewerage system and release effluent directly into waterways!

The major problem is permeability.

Sea lice: That nasty rash you get after swimming in the ocean

Sea lice, the likely reason you’re itching after swimming in the ocean

Have you ever been ocean swimming and felt like you’ve got an itchy bite? or come out in a rash after open water swimming?

The chances are it’s the result of what’s commonly referred to as ‘sea lice’.

In fact, it’s not ‘sea lice’ or ‘sea louse’ in the way fishermen might think of it. This type of sea lice/louse is a marine parasite that affect fish by feeding on the mucus, epidermal tissue, and blood of host marine fish, and actually have nothing to do with the itchy rash you’ve experienced.
