It was Geraldton’s hottest September day in more than a century. Temperature records are being broken in WA today as a searing air mass spreads across the state’s north and west.
A high pressure system centred over the Great Australian Bight is causing a pool of hot air to intensify over northwestern Australia, with temperatures soaring 15ºC above average in some areas today.
