Fire up the BBQ for Father's Day as it could be the warmest on record in Melbourne. Warmth is spilling into Melbourne over the weekend and into next week, with the warmest start to spring on record, following on from the warmest winter on record. Melbourne is likely to reach at least 23 degrees from this Saturday until Wednesday of next week. The earliest after winter a five day run has been this warm was between 19th-23rd September back in 1926. If it happens this time round it will be earlier by almost three weeks. The warm temperatures are coming off the back of Melbourne's warmest winter on record with maxima set to average 16 degrees and minima around 8.5 degrees. This is well above the long-term average of 14.2 degrees and 6.5 degrees. This weekend will be amazing in Melbourne, particularly on Father's day when the mercury is set to rise to 25 degrees. This will be far warmer than any Father's Day in the last decade which have reached 21.5 degrees at most. There is the chance that it will be the warmest Father's Day on record, set at 26.8 degrees in 1914. It will be a day for picnics, BBQ's or a trip to the beach with Dad. The reason for the sudden change in temperature is a fairly abrupt change in weather patterns for the southeast. Only a week ago Melbourne rounded out a five day run staying below 16 degrees due to a succession of cold fronts. Since then a dominance of high pressure systems have produced calmer weather and occasional northerlies have dragged the hot air in from the north. This should be the warmest week in Melbourne for the next few weeks, so get outside and enjoy the unseasonably warm weather.
