How to reduce the risk of Covid-19 at the beach or the pool

Australians are emerging from winter and, where possible, enjoying trips to beaches and public pools. Beach-side picnics, barbecues and get-togethers are back on the cards for many of us.

While daily COVID-19 case numbers have been looking promising in most places lately, we’re still very much in a pandemic; your spring and summertime social activities might look a little different this year.

Here’s how to stay safe if you’re planning a trip to the beach or public pool.

The three golden rules

Outdoor activities are associated with reduced COVID-19 transmission risk compared with indoor activities. That said, whatever your plans, the three golden rules still apply: stay home if you are sick; keep up the hand hygiene; and maintain physical distancing from others.

If you’re sick, you shouldn’t be socialising at all. You should be getting a COVID-19 test and self-isolating while you wait for results. Even outdoors, one sick person can spread COVID-19 to a large number of people.

Going to the beach

Firstly, pick a quieter beach. The extra time it takes to research and travel to a more secluded beach may be a hassle, but it’s less risky than going to a crowded beach (and often nicer, too).

Consider driving or cycling to the beach (if possible) rather than taking public transport. If you do use public transport, pick an off-peak time of day and wear a mask – avoid rush hour.

When you arrive, put your towels down in a spot on the sand at least 1.5m away from others – more is better, if you can. You should still swim between the flags, but you don’t need to be sitting close to other people.

When swimming between the flags, it might feel crowded in the water during busy times or at busy beaches. If you’re in that situation, think about reducing the time spent in the water – go in for five minutes, then come out for a bit, then go back in for another five, so you’re not having prolonged contact next to another person.

If you see someone expelling mucus into a wave, try to avoid that wave and person if you can.

Remember to stay COVID-safe if you’re at a cafe for a post-swim snack or ice-block. Don’t bunch up in lines close to other people, and maintain physical distance from others if you’re sitting down for a meal.

In the past, it might have felt normal to share a plate of hot chips with mates, or even offer a friend a sip of your drink – but we don’t do that any more. If you’re having a beach-side picnic, make sure you’re not sharing utensils, double-dipping in the hummus, or sticking your fingers into a shared bowl of olives.

Of course, all these general principles also apply to other outdoor swimming locations, such as rivers and dams.

Going to the pool

The ocean is probably less risky than going to the pool, because there’s more movement of water and a high level of dilution.

So you need to approach public pools with a degree of caution.

But if you have no choice, are living away from the coast and want a swim, it’s probably fine to go to an outdoor pool – especially if you’re living in an area with a low level of community transmission. (You can find out community transmission rates in your area from your state health department website.)

Outdoor pools are less risky than indoor pools because of increased air flow. Confined spaces are associated with increased risk of COVID-19 transmission

Choose the right time to go a pool. Transmission risk decreases with fewer people, so try to go at less-busy times. In the morning, the pool water has likely had time to be well-filtered and well-chlorinated overnight, and not many people have swum in it yet that day.

Chlorine kills coronavirus. The US Centers for Disease Control says it is “not aware of any scientific reports of the virus that causes COVID-19 spreading to people through the water in pools, hot tubs, or water playgrounds […] including saltwater pools”.

The risk of transmission, albeit potentially low, would also depend on how chlorinated the pool is, and how long any coronavirus that may be in the water is exposed to chlorine before coming into contact with another person.

Theoretically, if someone is carrying the virus and some mucus goes out of their mouth and into the pool, there might be a certain period of time before any virus in that mucus is inactivated by the chlorine. If it gets to you before that inactivation happens, then it is possibly a bit more risky.

Avoiding the change rooms is another way to reduce risk, as these are often in a confined space. Being careful to maintain physical distancing in the pool, poolside, and at the cafe are also important measures.

In general, it should be fine to take the kids to the pool, but if there was a degree of community transmission in your area, perhaps reconsider. There’s growing evidence kids are less susceptible to COVID-19 compared to adults, but it doesn’t necessarily mean they’re not transmitting it.

Whatever you have planned this summer, think about the local risks, and what you can do to reduce them.
