Heading to the Beach This Summer? Here’s What You Should Know to Stay Safe

Summer in Ottawa is the perfect time to cool off at one of our beautiful supervised beaches. Whether you’re planning a family outing or just need a break from the heat, it’s important to keep safety top of mind when swimming in natural waters. Ottawa Public Health (OPH) works hard to keep residents informed about beach conditions, but there are also a few things you can watch for to help keep yourself and your loved ones safe.

Before You Swim

Ottawa’s beaches usually meet water quality standards about 85% of the time, which is great news—but unlike swimming pools, open water has more variables to consider. Heavy rainfall in the last 24 to 48 hours can wash contaminants like bird droppings or pet waste into the water. If the water looks cloudy or murky—especially if you can’t see your feet in waist-deep water—it’s safer to wait. Keep an eye out for large groups of birds, dead fish, algae, or floating debris. These can be signs that the water may not be ideal for swimming.

If you have open cuts or wounds, it’s best to avoid swimming until they’ve healed, as bacteria in natural water can lead to infections.

At the Beach

When you arrive at the beach, a few simple steps can help keep your swim both safe and fun. Always swim in supervised areas between 12 p.m. and 7 p.m., when lifeguards are on duty. Keep children within arm’s reach at all times—even if they’re strong swimmers—and make sure they use properly fitted life jackets if needed. Babies who can’t sit without support should always be held securely.

Try to keep your head above the water and avoid swallowing it. Taking kids to the bathroom before they swim helps reduce the chance of accidents in the water. And as tempting as it might be to relax with a drink, it’s important to avoid alcohol, cannabis, or any other substances when you’re swimming or supervising others.

After Your Swim

Once you’re out of the water, rinse off as soon as possible and dry your ears well. Washing your hands before eating or handling food is also a good habit, especially if you’ve been digging or playing in the sand.

How Beaches Are Monitored

OPH tests water samples weekly during the summer at Ottawa’s supervised beaches to check for E. coli bacteria. This helps identify the potential presence of other illness-causing organisms. Because test results take about 18 to 24 hours to process, the beach signs you see (open or closed) are based on the previous day’s water quality—not real-time conditions.

That’s why it’s so important to use your best judgment based on what you see when you get to the beach. Weather, water clarity, and beach activity all play a role in safety.

Enjoy Your Summer—Safely

By staying alert and following a few simple guidelines, we can all enjoy a healthy and fun beach season in Ottawa. Whether you’re building sandcastles with the kids or just dipping your toes in after work, a little awareness goes a long way.
