Melbourne is set to get one final blast of sunny weather on Tuesday before autumn really kicks in.

The Bureau of Meteorology is tipping a top of 29 for Tuesday, with hot and fast winds in the morning creating weather that may have many considering a trip down to St Kilda beach.

If you enjoy the beach, this is probably your last chance. It's going to rain hard on Wednesday, and remain cold all week, according to the Bureau of Meteorology's seven-day forecast.
