Can you swim in Lake Ontario?

Yes, you can swim, but water temperatures can be chilly even in summer. Beaches like Toronto’s Woodbine and Rochester’s Ontario Beach are popular spots to take a dip. Just watch out for currents and make sure there’s a lifeguard on duty if you’re not familiar with the lake. Algae blooms can happen, so check local advisories before swimming. Swimming here is fun, but it’s definitely not the same as a tropical beach.
