The Lowdown

Alright, Rusty here. Let's have a look at what's coming up.

We've got one spot to focus on for the next couple of weeks: Black Rocks Jetty. It's a reef break, and right now the water's sitting at 77° – that's a full 4° warmer than normal for this time of year, so you're in for a treat if you like it warm.

The real standout is Thursday the 27th of August. Get up early. We're looking at a solid 10 ft SSW groundswell, a very long 17 second period, and glassy conditions with near-zero wind. The wave energy is pumping hard at 4932 – that's serious power. This is only for experienced surfers though; anything over 8 ft is expert territory. The swell direction is spot-on for this exposed reef. A few others might be around, but it's a "sometimes" crowd spot, so you could have it relatively quiet.

The run-up to that is good too. Monday the 24th has 7 ft to 8 ft SSW swell, glassy both morning and afternoon, with excellent conditions for experienced surfers. Tuesday the 25th drops a little to 5 ft but stays clean with a cross-off wind.

That Thursday peak is the big moment. Friday the 28th pushes up to 13 ft in the morning, but the wind turns cross-onshore and it gets a bit lumpy. Still, if you're a charger and don't mind some chop, that's a lot of energy (7182). But for clean waves, Thursday is your day.

The weekend (29th-30th) stays big – 10 ft to 12 ft – but the winds are messy, either cross-shore or cross-onshore with moderate breeze. Sunday the 30th morning cleans up to glassy with 7 ft SSW, a good second choice.

After that, there's a real lull. From Monday the 31st afternoon all the way through to Wednesday the 3rd of September, it’s mostly onshore, tiny, and poor – a solid 4-day gap with nothing worth paddling out for. Hang up the board or go for a fish.

Things start stirring again on Friday the 4th of September. A morning glass-off with 4 ft SSW groundswell at a very long 19 second period looks promising, but the afternoon turns onshore. Then Sunday the 6th of September brings back some real hope: 6 ft SW swell, glassy calm in the morning, cleaning up to a clean cross-off by the afternoon. That's a solid day for experienced surfers with that 14 second period and moderate energy (1382 to 1704). Monday the 7th gets messy again with cross-onshore wind and rain showers, so that Sunday is the late-period pick.

The final day, Tuesday the 8th of September, is blown out by a 16 mph SSE cross-shore wind. Not worth it.

So, to sum it up: Thursday the 27th of August is the absolute standout – big, glassy, long-period SSW groundswell, expert-only, and warm water. If you miss that, Sunday the 6th of September is your next best bet for some clean, solid waves.

Rusty.
