Steady swell all week with workable winds
South Australian Forecast (issued Monday 9th March)
Best Days: Both coasts Tuesday and Wednesday morning, Mid Coast Thursday, Friday both coasts during the morning
Saturday was better than Friday down South with a period of lighter W'ly winds around Victor through the morning and good easing S/SW swell. Winds swung back onshore mid-late morning through, creating poor conditions for the rest of the day.
Sunday morning was the time to surf with a better W/NW breeze and fun amount of swell, but again a SW change pushed through late morning, creating average conditions into the afternoon. The Mid Coast was tiny and far from ideal with light variable winds from the west east morning.
Today a new SW groundswell has filled in under morning W/NW winds down South but a S'ly change has since moved through creating terrible conditions. The Mid has cleaned up though with 1-1.5ft of swell and a lighter more variable onshore wind.
This week (Mar 10 - 13)
Today's increase in SW groundswell was generated by an initial strong polar front on Friday, but a secondary better system since developed and pushed over the already active sea state, generating a larger SW groundswell pulse for late today and tomorrow.
The Middleton stretch should offer solid 4-5ft sets with 6ft+ waves out at Waits and Parsons and 1-2ft waves on the Mid.
Today's onshore change will peter out overnight leaving variable winds across both coasts tomorrow that should be offshore on the Mid and likely light offshore down South.
Afternoon sea breezes are due so make the most of the morning.
The swell should drop back a touch through Wednesday but moderate amounts of SW groundswell are due to persist across the South Coast through the rest of the week. This is due to continued strong frontal activity under the country from today until Thursday.
Size wise Middleton should hang in the 3-4ft range through Thursday and Friday with larger 5-6ft sets at Waits and Parsons. The Mid looks to continue in the 1ft to occasionally 2ft range for the rest of the week on the favourable parts of the tide.
Winds will remain favourable for both coasts Wednesday morning with a variable breeze on the Mid and light W/NW'ly down South but an onshore change through the day will then leave S/SE winds for Thursday (favouring the Mid) and then E'ly winds Friday morning (tending E/NE down South).
This weekend onwards (Mar 14 onwards)
This week's swell will tail away gradually over the weekend with nothing significant on the cards for next week at this stage besides a small pulse of S/SW swell Monday.
Winds are looking to shift back to the SE Saturday morning, but Sunday should see better E/NE winds for the South Coast with a small dropping 2-3ft wave at Middleton and 3-4ft sets at Waits.
