A mixture of SW swell and S windswell is then forecast to arrive over the weekend, bumping surf up a touch on the South Coast. Unfortunately winds are forecast to be onshore during this period. Forecast Overview Only average surf on the South Coast to start September with winds onshore and swell holding in the 2 to 3ft range. Meanwhile the Mid Coast has been hovering around the 1ft+ mark, with only ok waves on offer. A ridge of high pressure, drops down into The Bight through the middle to end of the week, inhibiting the close range storm track. As a result we should see more organised refracted SW groundswell arriving through the end of the week, with winds swinging more E on Friday. A low pressure system appears to drop into The Bight this weekend, deepening as it moves over Victoria. This storm appears to have swell producing potential, with a S fetch aimed toward (and in close proximity to) our swell window on Saturday. Resulting windswell is forecast to arrive on the weekend, pushing wave heights back up on the South Coast. Due to the strong S direction of the swell, most of the energy will not get into the Mid Coast. This pulse of windswell is forecast to be short-lived with the storm moving rapidly away to the east on Sunday. The storm track then calms down early next week, with long range groundswell generating small inconsistent surf across both coasts. Further Outlook The Southern Ocean storm track appears to remain relatively zonal beneath mainland Australia through the longer range outlook. Longer range wave models are showing small to mid range groundswell arriving through most of next week.
