With temperatures due to spike at 37 degrees in Perth on Saturday and big crowds expected at the beaches people have been warned about everything from sunburn to rip tides as well as boat safety, bush fires and burn offs.
Surf Life Saving WA General Manager Chris Peck said beach goers need to watch out for dangerous rips.
"We are worried about rip conditions with the longer swell period, up to 16 seconds between each swell, which will mean a large volume of water coming into that beach environment which will create rips and probably flash rips," he said.
"Rips are still the number one cause of drowning deaths on Australian beaches and on average three people die per year in Western Australia as a result of tides."
He also urged beach goers to swim between the flags, swim with a friend and not to take unnecessary risks.

Volunteer sea rescue groups are expecting big numbers of leisure on the rivers and waters off the metropolitan coast.
Fremantle Volunteer Sea Rescue published a video on their Facebook page urging boaties to make sure they have all the necessary safety equipment on board and that their vessel is well maintained.
"The most important thing is to make sure that someone knows where you are going and what time you are going to be back.
"It's a really big ocean out there and it is hard to find you if we don't know where to look," warns the video.
The Department of Fire and Emergency Services website shows a number of bushfires and burn offs in the south west and north east of the state.
Most of the bushfires are simply being monitored. The only bushfire advice active on Saturday morning was for a blaze in the King Leopold Ranges in the shire of Derby.
A bushfire alarm was recorded for Carmel in the shire of Kalamunda around 8am on Saturday. We'll bring you more details as they come to hand.
In and around the Perth metropolitan area there are active burn- offs at Chittering, Forrestdale and Parkland, Mandurah.
Across the south west there are more burn offs at Bridgetown, Leschenault in Harvey, Noggerup and Paynedale in Donnybrook-Balingup, Windy Harbour in Manjimup, Hay in Denmark and Coolup in Murray.
In the northern parts of the state temperatures are set to make Perth's 37 degrees look mild.
Fitzroy Crossing is forecast to hit 45 and there is a severe fire weather warning for the Gascoyne region with temperatures of 44 degrees forecast along with gusting north easterly winds shifting to north westerly by the afternoon.
People in the area are urged to put their Bushfire Survival Plan into operation and monitor and fire and weather situation constantly through local radio broadcasts as well as watching the DFES and BOM websites.
If you've got the time and the means there are some places you can go to escape the hot weather and dire warnings.
Bunbury, Busselton and Margaret River are forecast to hit maximum temperatures in the late 20s. Augusta will hit just 23 and Bremer Bay 21.
