(ABC News: David Weber)"So we should be expecting a continued trend towards warmer autumns, and we know that southern Western Australia has quite a clear drying trend as well which we expect to continue over the coming decades."Any given autumn can be different from the trend but this general pattern we expect to become more common."Warm autumn forecast for WAPhoto shows Members of the public at a crowded beach during sunset.After a scorching summer and record-breaking temperatures in 2024, Western Australia is set for another warmer-than-usual autumn.Dr King said the trend was already having significant impact on the state's marine life, and that was set to continue."Generally having higher temperatures stressed coral and increases the likelihood of bleaching and even coral mortality," he said."The marine heatwave around the north west coast of Australia has been particularly extreme in the last couple of months."He suggested the warmer weather had been caused by the impact of man-made emissions."It's very clear when we look at weather station data over the last 100 or 150 years that there's a very clear trend towards higher temperatures, including in the autumn," Dr Kind said.The beach could still be an option for many seeking to stay cool during the daytime this week.
