Warm weather in Western Australia's Shark Bay region has attracted some unusual beach goers to Monkey Mia.

With the mercury hovering around the 40s early this week, local Katie Hughes says five emus decided to take a dip and cool their heels yesterday.

"It was really really hot, probably around 41 degrees, and we noticed them having a stroll along beach," she said.

"They got to the water's edge, had a look, had a look at each other and then in they went!

"They crouched down and had a bit of a roll around to cool off.

"It was awesome, I just had to take a photo."

Ms Hughes says the emus are regular visitors to the beach but she has never seen them go for a swim.

It's the height of wildlife season in Monkey Mia, which attracts plenty of tourists for its dolphins.

"There are tonnes of other animals around at the moment," said Ms Hughes.

"We've got a good selection of dolphins and dugongs, we're seeing them every day and they're pretty rare.

"We've got a couple of species of turtles, sharks and an amazing number of rays too."

The Bureau is forecasting cooler weather for the region for the rest of this week, with temperatures dropping to the 30s.
