Sponge bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what Sponge Bay has lined up for us. It’s a beach and reef setup, fairly exposed to the SSE swell, and the water is sitting at 54°, which is a bit colder than normal for this time of year – you’ll feel that difference for sure.

The first real chance for a paddle comes Saturday afternoon, the 22nd of August. We’ve got a tiny 3ft SSE groundswell rolling in with a long 12-second period, and the wind is glassy – dead calm. The energy is moderate (188), but honestly, it’s pretty ordinary. The waves are surfable but nothing to write home about. It’s a start.

Sunday and Monday are a write-off. The 23rd is a mess with strong cross-off winds and tiny waves, and the 24th is only slightly better but still very ordinary. You’re better off waiting.

Tuesday morning, the 25th of August, is where things start to look up. We get a 3ft SSE swell, a solid 13-second period, and a gentle cross-off breeze. The energy is building nicely (347), and the conditions are clean. This is a proper good session for a beginner-friendly spot – clean waves, easy paddling, and no crowds to worry about. Afternoon gets a little cross-shore, so stick to the morning.

Wednesday the 26th has a beautiful 2ft SSE groundswell with a long 16-second period in the afternoon, light cross-off wind, and a good energy reading (290). It’s clean and the waves will have some shape. Thursday the 27th is even better – 3ft SSE swell, 17-second period, light wind, and the energy jumps to 407. That’s a standout morning for sure. Glassy conditions on the Thursday afternoon too.

Friday the 28th has the biggest swell of the first week – 4ft SSE with a 16-second period – but the wind is a bit stronger and the conditions are marginal. Still worth a look if you’re keen, but Thursday is the better bet.

After that, we hit a rough patch. From Saturday the 29th through Monday the 31st, it’s mostly poor surf with cross-off and cross-on winds, and the energy drops right off. There’s a brief window on Saturday afternoon with a 2ft SE swell and offshore wind, but it’s still very ordinary.

Now, looking into the first week of September. Tuesday the 1st is a real highlight. Morning has a 2ft S swell with an incredible 18-second period – that’s very long period groundswell, best for the reef section – and the energy is solid (326). Clean conditions. The afternoon is even better: 2ft SSE, same 18-second period, energy at 428, and light cross-off wind. That’s a quality day, but remember, it’s over a week away, so keep an eye on the forecasts.

Wednesday the 2nd is blown out by strong cross-off winds. Thursday the 3rd is back on – 3ft SSE, 15-second period, glassy conditions in the afternoon. That’s a beauty.

Friday the 4th and Saturday the 5th are rough with rain and strong onshore winds. But then Sunday morning, the 6th of September, brings the biggest swell of the whole outlook: 5ft SSE at 11 seconds. The energy is strong (598), and it’s glassy. That’s a proper session, though at 5ft it might be pushing it for beginners – the reef could make it a bit much. The afternoon is clean but a little smaller.

So, if you’re picking your days: Thursday morning, 27th August is the standout of the first week – clean, long-period swell, and light wind. For the second week, Tuesday afternoon, 1st September and Thursday afternoon, 3rd September are the ones to circle. Sunday the 6th has the most size but is for more experienced crew.

Rusty.
