As the days get sunnier and warmer, it’s no surprise that people are longing to head to the beach. But ever since the start of the coronavirus crisis, beaches have been a point of controversy — remember the photos of Florida beaches packed with spring break revelers?

As with any public outdoor activity, going to the beach these days can have both benefits and risks. The Centers for Disease Control and Prevention urges people to go outside to relieve stress and get fresh air and vitamin D. The key is to take the appropriate precautions — and to stay home if you are sick.

If you’re hoping a visit to the beach is in your not-too-distant future, here’s what you need to know to do it safely.

Check the rules before you go

Coronavirus-related requirements for beaches may differ among states — and even among neighboring towns. While some are open for all activities without restriction, others allow beach access only for running, walking, swimming or fishing, but not for lounging or picnicking.

Some areas are also implementing measures to help reduce crowding, such as limiting parking lots to 50 percent capacity and selling fewer beach passes. Mask policies vary, too. Contact your local beach or public health department for current guidelines, and do your part by going home if the parking lot and beach are too crowded.

The CDC also suggests limiting visits to beaches (and other outdoor recreation areas, such as parks) to those close to home. Traveling long distances means you’ll probably have to stop along the way and potentially contributes to the spread of the virus.

And if you do go to the beach, don’t forget to take along disinfecting wipes and hand sanitizer, and to wash your hands as soon as you return home.

Swim safely

One potential route to infection is the possibility that saliva or mucus from an infected person might end up in the water where you’re swimming.

Although there is no data on how long the virus can live in water, research by Charles Gerba, professor of virology and environmental science at University of Arizona in Tucson, shows that coronaviruses that cause the common cold can survive in fresh water for up to three days. “We don’t have studies on seawater, but usually viruses survive for less time in salt water,” he says.

But even if the virus is present in water, experts agree that it would be very unlikely for it to be in a high enough concentration to get you sick.

The bigger threat, even in the water, is being close enough to an infected person to directly inhale virus particles they exhale, sneeze or cough. “As a precaution, I would recommend practicing social distancing in the water just as you would on land,” says Mark D. Sobsey, a research professor at University of North Carolina Gillings School of Global Public Health in Chapel Hill, who studies viruses and bacteria in water.

Another concern people may have is catching the virus if any wastewater (used water from homes or businesses) has flowed into the ocean. “The risk of that causing infection is virtually none,” says Greg Kester, director of renewable resource programs at the California Association of Sanitation Agencies, a nonprofit organization. “The covid-19 virus is completely inactivated during the wastewater treatment process.”

Swimming in water that contains raw sewage or contaminated runoff water poses health risks, such as gastroenteritis, but the chance of contracting the coronavirus from it is slim as well. Although the virus has been found in fecal matter, “there is new evidence that the virus infectivity is destroyed by the intestinal tract,” Sobsey says.

Still, as a precaution, it’s a good idea to consider wading or swimming without putting your head in the water. And avoid swallowing water when swimming.

Practice social distancing

The same precautions you take shopping at the grocery store, walking down the street or going to a park apply to beach visits, too.

That means continuing good social distancing practices, including maintaining at least six feet between yourself and people not in your household.

“Part of the problem with the beach is that the atmosphere makes people revert to a pre-covid mind-set,” says William Schaffner, professor of medicine and infectious diseases at the Vanderbilt University School of Medicine in Nashville, and medical director of the National Foundation for Infectious Diseases. “Unlike being somewhere like the grocery store, your sense of self-preservation and of being concerned about your neighbors diminishes just because of that relaxed beach atmosphere.”

When to wear a mask

If photos of some recent beachgoers are any indication, that casual atmosphere may also lead to forgoing masks. For instance, over the first weekend in May, officials in Miami Beach issued over 7,000 verbal warnings to non-mask-wearing visitors at a shoreline park (and eventually resorted to shutting the park down). The CDC recommends wearing cloth face coverings “in public settings where social distancing measures are difficult to maintain.”

Check with your local health department to see if wearing a mask in parks and on beaches is mandatory in your area. If not, and if you can set up your beach towel at least six feet away from anyone not in your household, you may be able to safely remove your mask. “If you’re clearly separate from other people, I think you’re okay,” Schaffner says. The wind at the beach may actually make it safer than some other spots, he says, because the wind helps diffuse virus particles in the air.

But he recommends that you have a mask with you and put it on (carefully) if you get up to go for a walk and anywhere you might encounter more people in proximity.

Don't count on open facilities

You should definitely “go” before you go, and don’t plan to stay at the ocean or lake all day.

Even in places where beaches have opened, their associated facilities — bathrooms and concession stands — have not. These facilities have many high-touch surfaces — doorknobs, toilet handles, faucets — that increase users’ odds of picking up virus particles on their fingers. According to a study published in March in the New England Journal of Medicine, measurable amounts of the coronavirus can live on plastic and stainless steel surfaces for up to 72 hours.

Remember safety basics

With so much of our energy and attention focused on coronavirus safety, common beach precautions might slip your mind. Swim responsibly. And be careful not to wander too far from a lifeguard-protected zone in an attempt to keep your social distance from other swimmers.

Coronavirus worries are also no excuse to ignore sun protection while at the beach. Joshua Zeichner, director of cosmetic and clinical research at Mount Sinai Hospital in New York urges all beachgoers to practice smart sun protection. This includes:

●Wearing protective clothing and a wide-brimmed hat.

●Using a broad-spectrum sunscreen with an SPF of 30 or higher.

●Applying a full ounce of sunscreen for your entire body. If you’re not in a bathing suit, use a quarter-sized dollop for your face, ears and neck, and one for each leg and arm.

●Reapplying every two hours or after swimming or heavy sweating.

●Applying sunscreen to your entire face even if you’re wearing a mask.

Vaccines: The CDC recommends that everyone age 5 and older get an updated covid booster shot. New federal data shows adults who received the updated shots cut their risk of being hospitalized with covid-19 by 50 percent. Here’s guidance on when you should get the omicron booster and how vaccine efficacy could be affected by your prior infections.
