Sydney will continue to bask in the glorious sun for a few more days after a stunning weekend. So far during September Sydney has only had one day that failed to reach above 20 degrees. Today will go well beyond this temperature. It will be the first time in 24 years that Sydney has gone ten days into spring with only one day below 20 degrees. Sydney has averaged 23 degrees so far this month, three above the September average. This follows on from a warm end to winter, with August averaging 20 degrees, two above the long term average. Unfortunately for many in Sydney the warmest days have fallen mid-week, while the weekends have been the coolest part of the week. During the last five weeks the average Saturday and Sunday have had a top of 19 degrees while the average Wednesday has been 24 degrees. This mid-week warmth has favoured those who can get out during the week, like shift workers and university students. The pattern of cool weekends and midweek warmth has been due to the consistent arrival of a cold front each week around Thursday. This pattern will continue again this week with Wednesday set to reach 25 degrees before a cold front arrives on Thursday afternoon bringing a shower or two. This will be followed by a cooler and mostly sunny weekend.
