After a cool end to August and a not so warm start to September for Sydney, things look to heat up a touch heading into the middle of the month. As the middle of the first month of spring approaches, temperatures look to trend closer to average than they have done of late, with indications of reaching a few degrees above average in around a weeks time. Before this, however, another cooler than average day is expected on Saturday 8th, as a cold front to the south briefly introduces a cooler airmass to the region. Brighter conditions should prevail from the end of the weekend with clear skies and temperatures beginning to pick up. Much warmer air ahead of an approaching cold front will slowly make its way over the region into the middle of the week, with northerly component winds funneling the heat across the southeast. At this stage, heat is expected to peak on Wednesday, possibly reaching the mid-to-high 20's. Should the mercury climb above 26 degrees it will be the warmest day for Sydney since early May. If you prefer these warmer conditions make the most of the upcoming warmth as cooler conditions will swiftly return as the cold front moves through.
