The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell coming through for Black Rocks Jetty, but it’s a tale of two halves. The first week is all about solid, clean surf for the experienced crew, and then the second week looks like it might serve up something truly special.

Overall Pattern

We’re kicking off with a consistent pulse of SSW groundswell that sticks around for days. The water temperature is sitting at 77°F, which is a touch warmer than normal for this time of year, so you might not need the thickest rubber. The first few days are all about size and quality, with the standout window looking like Saturday afternoon. From there, the swell dips a bit mid-week before a big, powerful south-west groundswell arrives late in the second week. Keep your eyes on the end of the month.

Friday, 14th August

Friday morning is a bit of a washout with a light cross-onshore wind making things a little bumpy, but the swell is already a solid 6 ft from the SSW. The afternoon is where it gets interesting. The wind goes glassy, and we’ve got clean 6 ft SSW swell. It’s a good start, but the real fun is still coming.

Saturday, 15th August – The First Standout

If you can get out on Saturday afternoon, do it. This is the best on offer in the first week. We’re looking at 7 ft of SSW groundswell with a very long 18-second period generating a massive 5328 combined energy. The wind is light and cross-off, which will keep the faces clean. This is a setup for expert surfers only. The waves will have plenty of power, and with that long period, expect long, clean lines at this reef break. It’s going to be a proper session.

Sunday, 16th August

The swell sticks around at 8 ft on Sunday morning, but it’s a bit onshore, making it tricky. Sunday afternoon cleans up with a cross-off wind and 8 ft swell, but it’s not as good as Saturday. The energy is still high, but Saturday is the clear winner.

Monday, 17th August through Thursday, 21st August

The swell backs off significantly. Monday sees 4 ft, and it drops further to under 3 ft by Tuesday and Wednesday. The wind is a mixed bag, with some glassy periods but generally weak conditions. The energy is low (under 500 in the combined energy readings). It’s a quiet patch, a good time to rest or fix your dings. Friday the 21st shows a hint of life with 4 ft glassy conditions in the morning, but it’s not a standout.

Saturday, 22nd August & Sunday, 23rd August

We get a bit of a pulse back. Saturday delivers 6 ft to 6 ft of clean SSW swell with glassy conditions both morning and afternoon. The energy is back up to 1375, and it’s excellent for experienced surfers. Sunday sees a jump to 7 ft, but with a cross-onshore wind in the morning, it’s a bit lumpy. The afternoon goes glassy again with 7 ft, which is a solid session.

Tuesday, 25th August – The Second Standout (Watch This Space)

Now we’re talking. This is the one to circle on the calendar. Tuesday afternoon sees a massive 12 ft of SW groundswell with a 17-second period, pushing a combined energy of 6144. The wind is forecast to be glassy. This is exceptional surf for expert surfers only. The sheer size and power will be unreal. This is a long-range call, so keep an eye on the forecasts, but if it holds, this will be the session of the month.

Wednesday, 26th August through Saturday, 29th August

The big swell lingers. Wednesday morning is still 8 ft and glassy, but the wind turns onshore in the afternoon. Thursday and Friday are still solid, with 7 ft and 6 ft respectively, with some glassy windows. Saturday the 29th keeps the energy high with 7 ft, but it’s a bit onshore in the morning before turning glassy in the afternoon. It’s a great end to the run, but Tuesday afternoon is the absolute standout.

Keep your head on a swivel for that big one on the 25th. Until next time, this is Rusty, signing off.
