Swimmers have been evacuated from the water at popular beaches after a tagged tiger shark was detected at Floreat about 7.35am and City Beach at 9.07am.

Scarborough Beach has been reopened after it closed because of earlier tiger shark detection at Ocean Reef, Mullaloo and Scarborough.

It was closed for about an hour.

Surf Life Saving WA tweeted at 6.15am that the popular beach had been "closed by Lifeguards due to shark detection".
