Melbourne's weather is really quite desirable. People are too harsh on it and don't give the credit it merits. The weather is great for the majority of the year, particularly from September - May. Doesn't rain too often. http://www.makemyessay.com/
Summer (Dec-Feb): It's sunny, and it's warm-hot! Accurate time of the year to head to the beaches around Melbourne or along the coast similar the Great Ocean Road, Wilsons Prom, Lakes Entrance, Mornington Peninsula etc. You see the occasional storm here and there, but it's usually a dry time of the year.
Autumn (Mar-May): This is more a beautiful time of the year. Temperatures are usually mild in the low-mid 20's, and it's sunny. The water temperature is accurate as well, so you can go for swims.
