Swim Guide is a website and smartphone app for iPhone® and Android. It helps you easily find your closest beaches, know at a glance which ones are safe for swimming, and share your love of beaches with friends and family.
Swim Guide delivers free real-time water quality information for over 7,000 beaches, lakes, rivers, and swimming holes in Canada, the U.S., Mexico, the Bahamas, Ireland, France, New Zealand, and Australia. Swim Guide is available in English, French, and Spanish.
Created and managed by Swim Drink Fish Canada (formerly Lake Ontario Waterkeeper), Swim Guide can be used by any public interest club, organization, or agency to share beach information with the public.
Find the best beaches
Swim Guide offers water quality information for a wide variety of beaches, ranging from city parks to remote lakes ideal for camping.
To find the beach that’s just right for you, browse the map or search for a beach by name. Beach descriptions tell you about amenities, lifeguards, where to park, and everything else you need to know to enjoy a day at the beach.
Have a favorite beach? Bookmark it! The next time you use the app, it will show up at the top of the beach list, making it easier for you to access information.
Don’t know how to get to the beach of your choice? The app also provides walking, driving, and transit directions.
Make sure to share your love of beaches with friends and family using our built-in social media sharing tools.
Beach water quality information that is easy to understand
Every beach is marked with an icon so you know when the water at your favorite beach meets government water quality standards.
Reliable beach water quality sources
Water quality information is gathered from government agencies or reported by Swim Guide affiliates themselves.
In any beach, look at the “Source” section. This will tell you who samples the water at each beach, how often, and what water quality standards apply. The date and time stamps tell you when the sample results were last verified by the Swim Guide affiliate.
Bacteria isn’t the only pollution that can ruin your trip to the beach. If you are concerned about water quality, litter, minor spills, or other problems, let us know using the pollution reporting tool in Swim Guide. This will alert your local affiliate to environmental problems. (In an emergency, always notify the appropriate authority.)
The history of Swim Guide
Swim Guide was created by the Lake Ontario Waterkeeper staff in Toronto to answer this simple question: is it safe to swim in Lake Ontario?
We thought it would be easy to find the answer. We were wrong.
As it turns out, reliable facts and figures about beach water quality are hard to come by. So we started compiling our own.
Over the years, more affiliates have started using Swim Guide to share information about swimmable waters with the public. As of 2019, Swim Guide is the most popular beach information service in the world.
The importance of Swim Guide
Every person should be able to swim at any beach on any day of the summer and never worry about health risks.
Without current, reliable data about water quality, people are vulnerable to illness and infection. When water isn’t safe to touch, people withdraw from it. And when the connection between us and our water fades, so does our instinct to protect it.
Swim Guide has helped to prevent thousands of waterborne illnesses simply by making it easy for people to know when their water is contaminated and when it is clean for swimming.
Swim Guide is helping to identify sources of water pollution so that together we can act to restore and maintain swimmable, drinkable, fishable waters.
