Melburnians may be shivering through their coldest day of the year so far, with a good chance of staying below 13 degrees all day. A cloudless night with light winds meant the temperature dropped to a chilly 7.2 degrees overnight. Since last night, Melbourne had only clawed its way to 9 degrees by 11am. Rain and cloud are likely to set in for the day meaning the temperature won't rise much from there. The cold air mass, clear sky and light winds overnight followed by daytime rain-cloud should create the near perfect recipe for a cold day in Melbourne. Melbourne would typically have a day below 13 degrees by this time of year. The last time it took until June to have a day that cold was in 2010. If today stays below 13 degrees it will be the coldest day so far this year. Breezy onshore winds coupled with sunny breaks will see tomorrow reach at least 13 degrees.
