Western Australia Surf Forecast by Craig Brokensha (issued Friday 1st August)

Best Days: Sunday, Monday moning, early Tuesday Perth north, Wednesday morning


Yesterday saw improving conditions across the coast with a building groundswell and good winds from Perth North while Margs saw S/SE winds through the morning ahead of lighter and straighter offshores into the afternoon.

Today a peak in large SW groundswell was seen with 8-10ft+ surf across Margs under straight offshore winds, while Perth was in the 2-3ft range and Geraldton didn't show as much size as it should of with the Jurien buoy showing a steep peak overnight and then drop into this morning.

This weekend (Aug 2 – Aug 3)

Today's swell is already on the ease and should drop further through tomorrow and bottom out. Winds are looking a little dicey as well so it's probably worth giving a miss with onshore W/NW tending S'ly winds in the South West and S/SW winds to the north.

Sunday's large and powerful W/SW groundswell is still on track with a very strong increase in size due during the day. Margs should pulse to 10ft+ later in the day with 3-4ft sets in Perth towards dark and 6-8ft surf showing near dark up at Gero.

Winds look excellent with moderate to fresh offshore tending variable winds across most locations.

Next Monday onwards (Jul 4 onwards)

The secondary pulse of SW groundswell on the cards for Monday has been downgraded a touch, with the secondary polar front moving in quickly behind the system responsible for Sunday's being weaker and not as favourably as aligned on Wednesday.

Still we should see a large reinforcing SW groundswell for Monday keeping exposed spots in the South West topped up with 8-10ft sets, 3ft waves around Perth. A drop in size is then due through Tuesday and further through the week with nothing too significant on the cards at all.

Winds on Monday will be good early and from the E/NE, but a swing to the N/NE is expected around Margs (lighter from the NE further north) so try and get in before lunch for the best conditions.

Tuesday is looking less favourable with N/NE tending N/NW winds, while Wednesday should see a return to better offshore winds from the E/NE, tending variable into the afternoon.

The next significant increase in swell is expected through next weekend and it looks to be very large and powerful. A couple of vigorous polar fronts firing up in the Heard Island region should generate two different pulses of SW groundswell, an initial moderate to large pulse Saturday followed by a much larger pulse Sunday afternoon.

Winds at this stage are a little hard to decipher but we may see light variable breezes. We'll have another look at this on Monday though. Have a great weekend!
