The 42-year-old delivered the weather forecast on British morning program GMTV after spending time on the couch to promote her latest album, Aphrodite.
After regular presenter Kirsty McCabe talked up "barbie" weather in some parts of the UK, Minogue was ushered on to update viewers on the situation in her hometown of Melbourne.
"The weather Down Under is going to be ... er, what's it going to be?" Minogue, dressed in a blue animal-print frock asked McCabe before regaining her composure and finishing with a flourish.
"A frosty start, showers clearing to a fine temperature of 14 degrees.
"Yay! My first weather forecast."
The program was renamed KMTV in her honour.
Minogue has been kept busy on the promotional trail for Aphrodite, her 11th studio release.
In an interview with Attitude magazine, Minogue, who was diagnosed with breast cancer in May 2005, said stress may have been the cause of her illness.
The singer admitted she used to get herself into "absolute states" before she went onstage to perform because she was so insecure.
"After being ill, I just thought, 'OK I don't know whether it was the stress that made me ill or the illness made me that way.' I don't know - chicken or egg," she said.
"I would just be in absolute states before performing and I think there's always been a little voice in my head from when I started out, 'She can't sing, she can't do this, she can't do that'.
Since her diagnosis, she said she no longer worried about it.
"I just don't stress about being on stage anymore. There could be combined reasons, maybe I've just reached my stride and I love that I've had to earn that. No one can give it to you. You've just got to learn the hard way."
Despite slow sales for the album's first single, All The Lovers, Aphrodite climbed to number one on iTunes on Friday.
