Holiday hotspots hiding a troubling health risk—Could this ruin your vacation?

As Memorial Day approaches and the scent of sunscreen and barbecue fills the air, millions of Americans are dusting off their beach chairs and plotting a sun-soaked escape to the coast.

But before you pack your cooler and head for the waves, there’s a hidden hazard lurking beneath those sparkling blue waters—one that could turn your holiday from a celebration into a sick day.

Let’s dive into the not-so-sunny side of America’s most beloved beaches, and what you need to know to keep your Memorial Day memorable for all the right reasons.



The Dirty Truth: Bacteria Hot Spots on America’s Beaches
A recent report from the Surfrider Foundation, a nonprofit dedicated to protecting our coasts, has revealed a grim reality.

Many of the country’s most popular beaches are teeming with bacteria levels that far exceed state health standards.

In fact, a whopping 80% of the 604 beaches and sampling sites tested in 2024 had at least one sample with bacteria counts high enough to pose a health risk.

What’s causing this spike in contamination? The answer isn’t always clear. The bacteria could be coming from human sewage, animal waste (think dogs, horses, and birds), or a combination of both.

The Surfrider Foundation is still working to pinpoint the exact sources, but the health risks are already well-documented.

What’s at Stake? The Health Risks of Polluted Water
Swimming in water contaminated with high levels of bacteria isn’t just unpleasant—it can be downright dangerous. Exposure can lead to a range of illnesses, including:

- Diarrhea and other gastrointestinal woes
- Rashes and skin infections
- Eye and ear infections
- Flu-like symptoms
- In severe cases, diseases like hepatitis

For older adults, children, and anyone with a weakened immune system, these risks are even more pronounced. A day at the beach should end with sandy toes and happy memories, not a trip to the doctor.

The Top 10 Most Contaminated Beaches in 2024
So, which beaches should you be wary of this Memorial Day? Here’s the Surfrider Foundation’s list of the worst offenders, based on the percentage of water samples that exceeded safe bacteria levels:

1. Kahalu'u, O'ahu, Hawai‘i – 92%
2. Waikomo Stream at Koloa Landing, Hawai‘i – 90%
3. Park View Kayak Launch, Miami Beach, Florida – 90%
4. Imperial Beach, California – 82%
5. Linda Mar Beach, Pacifica, California – 71%
6. South Sound Thea Foss Floating Dock, Tacoma, Washington – 64%
7. Ballard Park, Melbourne, Florida – 52%
8. Windmill Beach, Sag Harbor, New York – 43%
9. San Luis Creek Mouth, Avila Beach, California – 38%

These aren’t obscure, out-of-the-way spots. Many are iconic destinations, beloved by locals and tourists alike.

From the sun-drenched shores of Hawai‘i to the bustling boardwalks of California and Florida, no region is immune.

Why Is This Happening?
There’s no single culprit behind the rise in beach bacteria. Heavy rainfall can wash contaminants from streets and sewers into the ocean.

Aging infrastructure, like leaky septic systems and stormwater drains, can also contribute.

And let’s not forget the impact of wildlife and pets—every doggy dip or seagull pit stop adds to the microbial mix.

Climate change is making things worse, too. Warmer water temperatures and more frequent storms create ideal conditions for bacteria to thrive and spread.

The Funding Crisis: Are We Losing Our First Line of Defense?
If all this sounds alarming, here’s the kicker: the very programs designed to monitor and warn us about beach pollution are under threat.

The Trump administration’s proposed budget for 2026 eliminates all funding for the EPA’s BEACH Act Grants program, which supports water quality monitoring and public notification in 35 coastal states and territories.

Without this funding, families could be left in the dark about which beaches are safe and which are swimming in trouble.

The Surfrider Foundation is urging Congress to restore funding and protect our right to clean, safe beaches.

So, as you plan your Memorial Day getaway, remember: a little knowledge goes a long way. Stay informed, stay safe, and let’s keep our beaches beautiful—for ourselves, our families, and everyone who loves the sound of the surf.
