    Short-Term Analysis (to Thursday 4 Mar)
    SW deepwater swell energy will drop down through the middle of the week so we should expect a fading trend from the SW through at least Thursday. In saying that, conditions are still favourable under an offshore wind pattern and a continuation of low tide mornings filling in through the day. Leftover SW sets along the open southwest coast get the best of it through the mornings tide push but still surf hanging at low levels around waist to chest high range and other areas tend smaller Wednesday. By afternoons, expect conditions to give way to a seabreeze effect and this will result in mild texture through the second half of the day.

    A high pressure system holds position across the mid latitudes of the Indian Ocean and extends east across the bight. This high is interacting with a deepening heat trough and low pressure system residing over north WA. The two system are fueling a favourable easterly wind across the southern half of WA, projecting an offshore wind across the region. Meanwhile, TC Marian forms 2500km west of Exmouth today and worth noting for the long range forecast.

    For swell in the short term, we have a fading SW groundswell that will continue on a downward trend. Tomorrow will see the last stretch of SW groundswell and expect fading surf to decrease size and and metro breaks nearing flat midweek. This swell had previously seen a solid peak of deepwater sets last Saturday and offered overhead surf along the southwest breaks for the long weekend but this wave train has since dropped off steadily Monday and Tuesday.

    Offshore wind will continue to be the dominant factor with morning easterlies fueled by a heat trough that expands down the west coast. The wind coincides with an early morning low tide for groomed yet drained shape with small scale surf. By afternoon, the winds will ease and give way to a mild seabreeze so look for a gradual turn of wind and building tide as the day progresses, although surf is still generally small for the short term forecast. As SW swell trickles away throughWednesday and we can expect minor surf through this time, although as mentioned, some calm morning conditions ahead. For open spots of the southwest this offers some residual waist high surf on the beachies while swell will be losing strength.
