Perth is enduring scorching heat, with no relief from the famed Fremantle Doctor. The western capital reached 33 degrees on Wednesday before the afternoon seabreeze, known as the Fremantle Doctor, brought its sought-after relief. Today however, the Fremantle Doctor won't be offering its usual medicine. The low pressure trough that typically resides along the WA coastline has shifted off the coast today, meaning that the hot and dry easterly winds should prevail all day long between Perth and Margaret River. This will help temperatures to soar along the coastline into the high 30's. Tomorrow will be fairly similar, except that the Fremantle Doctor will have a little bit more of an influence during the late afternoon. Proper relief is not due until Saturday across the southwest. The low pressure trough will come inland and westerly winds will develop, bringing cooler air from the Indian Ocean. The cooler weather will be wonderful for getting out and about on the weekend during the school holidays.
