Autumn may be upon us, but the warm weather isn't going anywhere.

Victorians are set for an Indian summer as temperatures in March register well above average and rainfall remains at a decade-long low.

Bureau of Meteorology senior forecaster Richard Carlyon said warm weather would linger until the end of the month, with dry and hot conditions showing no signs of abating.

"Temperatures are sitting well above the long-term average for the month. We're sitting at 27.4 degrees at the moment. The average temperature for March is 23.9 degrees so that's about four degrees above average," he said.
