A firm ridge of high pressure will direct pleasantly warm and dry air across Perth leading into next week. The first half of the new week will see a run of above average daytime temperatures, with the mercury peaking in the low-20's each day. Winds will generally be light, so each day will feel as warm as the actual temperature suggests. There will be plenty of clear skies too, with the sunshine hours averaging at just over 8 hours each day between Monday and Thursday. Conditions will then change on Friday, as a frontal system impacts the region, with winds, cloud and showers all looking to increase significantly.
