The Lowdown
Right, let’s have a look at what’s coming our way here at Black Rocks Jetty (reef) . This is a proper reef set-up that loves a SW groundswell, and we’ve got a solid run of pulse coming through. The water temp is sitting pretty average for this time of year, so nothing wild there.
The week starts off a bit average. Saturday the 25th , we’ve got a clean 4ft SW groundswell in the morning with a gentle offshore NNE breeze – that’s a nice little session, but the afternoon gets a bit messy with the wind shifting. Sunday the 26th is similar, clean in the morning at 3ft but a bit cross-onshore later.
Now, Monday the 27th is where it really gets going. That morning is a standout! The swell jumps to 7ft from the SW with a period of 16 seconds – that’s proper groundswell, packing good energy (3461 combined). The wind is glassy. Zero. This is going to be an excellent, powerful session, but at 7ft, it’s firmly in the experienced surfers’ zone. Crowds are possible here, but with waves that size, it’ll thin out the pack.
Tuesday the 28th keeps the energy going with another 7ft SW swell, glassy again in the morning. This is a long run of quality. Wednesday the 29th remains clean and solid with 7ft, and Thursday the 30th stays glassy with a 6ft SW swell – still excellent conditions. This stretch from Monday morning through to Thursday morning is the heart of the outlook. Friday the 31st morning is another big one, 7ft and glassy, but the afternoon gets a cross-onshore wind.
After that, the size drops off. Saturday the 1st of August is a clean 5ft, nice fun waves, and Sunday the 2nd is small at 3ft. There’s a bit of a lull from there, with onshore winds and smaller surf until Tuesday the 4th afternoon, which lights up again with a 4ft, 20-second period groundswell – very long period, which is going to line up beautifully on this reef, glassy conditions. Wednesday the 5th morning has a clean 6ft.
After that, the last few days of the window drop off. Thursday the 6th and Friday the 7th are small and clean but weak, and Saturday the 8th and Sunday the 9th look poor with onshore winds and low energy.
So if you want the best, you’re looking at Monday the 27th morning and Tuesday the 28th morning. That’s the real deal. After that, the second week has a couple of nice glassy mornings, but the size is smaller and less consistent.
