The Principality Stadium’s roof will be open for what will be the Foo Fighters’ first performance in the Welsh capital for 17 years.
Organisers have said free water dispensers will be available inside the arena with forecasters predicting temperatures could reach 25C (77F).
Their Everything or Nothing at All tour is the band’s first in the UK since the death of drummer Taylor Hawkins.
The 19-date, four-month tour coincides with the release of their 11th album But Here We Are, their sixth number one record.
They have already packed out stadiums in London, Manchester and Glasgow and, after playing in Cardiff, will head to Birmingham for the final date of the two-week UK stopover.
The Principality Stadium show follows sell-out concerts at the 70,000-capacity venue from fellow US superstars Taylor Swift, Bruce Springsteen and Pink.
The stadium advised fans to “stay safe and hydrated whilst queuing in potential hot weather”.
“Once inside the stadium there are free water dispensers throughout the public concourses which we encourage fans to utilise,” a spokesperson said.
“Extra water will be handed out from the barriers for those on the standing floor areas.”
What time do the Foo Fighters in Cardiff start?
The Principality Stadium gates will open at 16:00 BST.

The Foos, founded by former Nirvana drummer Grohl in 1994, are expected to play all of their major hits from their 30-year back catalogue, as well as new ones from their latest album.
Fans can expect to sing along to classics like Everlong, The Pretender, All My Life, Monkey Wrench, My Hero and Learn To Fly.
Die-hards may also be treated to oldies but goodies from their 1995 debut album, written and recorded by Grohl himself, such as Big Me, I’ll Stick Around and This Is A Call.
What’s the weather forecast?
Tuesday is meant to be one of the warmest days of the year in Wales and BBC weather presenter Sabrina Lee says the outlook is bright for the Foo Fighters.
“It’ll feel very warm in the afternoon sunshine, with patchy cloud, gentle breezes and staying dry,” she said.

“After the concert, the dry theme is set to continue, with a mild humid feel.”
