Lorraine Menard reckons Scarborough beach in spring beats the Cote d'Azur hot spot of Nice in summer.
"The sand is better," the 27-year-old French tourist said.
"There are no rocks and the water is blue - at Nice it's black.
"It's wonderful here."
But Ms Menard and her compatriots Flora, Lea and Fanny - holidaymakers or students - weren't alone in enjoying yesterday's glorious weather ahead of an even hotter day today, forecast to reach 34C.
Surf Life Saving WA's operations supervisor Craig Bowley reported big numbers at popular city beaches yesterday as the mercury reached 28.5C at 3.30pm.
At almost 6pm yesterday, it was still a balmy 26.5C.
Mr Bowley said there were no reports of any major incidents.
"It's rather peaceful and perfect beach conditions," he said from City Beach.
And the water?
"Freezing cold," he said. "It's about 16 or 17 degrees and there are not a lot of people in the water."
Mr Bowley said not all surf lifesaving clubs were operating but more would open today.
He advised swimmers to keep within the flags.
More beachgoers are expected for today's public holiday.
Weather Bureau duty forecaster Richard Rattley said the expected maximum today was 34C with fresh and gusty north north-easterly winds before a light sea breeze this afternoon.
Cooler weather returns tomorrow, with maximums all week expected to be in the mid-to-low 20s.
