The Lowdown

Alright, Rusty here, and we’re running through the same window, but in feet and miles for you.

This 16-day stretch starts on the 1st of August, and Black Rocks Jetty is the main event. This is a reef break, exposed and very consistent, so it’s going to be the go-to spot. The water is a touch warmer than normal for this time of year, sitting at 77°F – not bad at all.

The big one to start with is Saturday afternoon, the 1st of August. We’ve got a solid 6ft swell from the SSW, with a long, juicy 14-second period. That’s real groundswell energy. The wind is glassy from the north, so the waves are going to be clean and lined up. The combined energy is a strong 1230. This is for the experienced crew though – 6ft on a reef is no joke.

Sunday the 2nd drops off. Morning swell is 4ft, but the wind is cross-on, so it’s a bit messy. The period is still 14 seconds, but it’s marginal. The afternoon sees a 5ft swell with a 16-second period, but the wind is cross, so it’s not clean. Wait for Monday.

Monday the 3rd is a good session. Swell is 4ft from the SW, but the wind is dead calm, glassy. The period is 14 seconds, so there’s a bit of a wait, but the waves will be clean. The energy is moderate at 965. A fun, easy morning.

Tuesday the 4th is small. A 2ft to 3ft swell with a 13-second period, offshore wind in the morning, so it’s clean. The energy is weak, so it’s a longboard or a soft-top day.

The middle of the week, Wednesday the 5th through Friday the 7th, is flat and messy. Swell is 2ft to 3ft, with onshore and cross-onshore winds. Energy is in the low hundreds, and the periods are short. Not worth the paddle.

Now, here’s a standout for the second week. Saturday the 8th of August, morning glass-off with a 4ft swell from the SW, but the period is a massive 18 seconds. That’s a long, powerful groundswell. The energy jumps to 813. This is going to be a clean, walled-up wave on the reef. Do not miss this.

The next big one is Tuesday the 11th of August. Morning glass, 5ft of SW swell, with a 15-second period. The energy is strong at 1100. This is another expert-level session, with clean, powerful lines. The afternoon gets a bit cross, but the morning is the pick.

Then, Friday the 14th of August. Morning glass, 6ft from the SSW, 14-second period, and the energy is a huge 1533. That’s pumping. The afternoon holds at 6ft with glassy conditions. This is excellent, powerful reef surf. For the experienced only.

The last few days, Saturday the 15th and Sunday the 16th, see the swell push up to 8ft and 7ft, but the wind is cross-on or onshore. The energy is massive, over 3000 on Saturday, but the wind is going to chop it up. It might be more of a kite day. The Sunday afternoon does glass off with a 6ft swell, so there’s a final window of clean, punchy waves.

The standout for the whole period is the morning of Saturday the 8th of August with that 18-second groundswell, and the morning of Friday the 14th of August with the 6ft glassy conditions. Those are the ones you set your alarm for.

Rusty.
