Sponge bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a look at what’s shaping up for us over the next couple of weeks.

It’s a pretty quiet start to the run. We’ve got a few days of nothing much to write home about, but patience is key because there’s a real standout window coming up mid-week that’s worth getting excited about. After a bit of a lull, the surf builds back towards the end of the second week, though that one’s a bit further out.

For the first break on the menu, we’re looking at Sponge Bay (Sponge-Bay). The water temp is sitting right where you’d expect for this time of year, so no need to dig out the extra rubber.

Monday 31 August is a write-off. Small, weak stuff with a moderate breeze, poor conditions all day.

Tuesday 1 September is still no good. The morning sees a jump in size to 10 ft, but it’s from the SSW and with a strong cross-onshore wind, it’s going to be a messy, lumpy mess even for the brave. The afternoon drops a bit but remains marginal.

Wednesday 2 September is our first real highlight. The morning is clean with a cross-off breeze and chest-high waves at 6 ft from the SSE, with a nice long period of 14 seconds giving them some push. The energy is moderate (1448). But the afternoon is the absolute gem. Glassy conditions, light easterly breeze, and the swell holding at 6 ft from the SSE, but the period stretches to a very long 17 seconds. That’s proper groundswell energy, and the combined energy is strong (2496). For a beach and reef set-up, these long-period swells can wrap around nicely, and the glassy surface will make for some unreal, clean lines. This is the standout session of the whole forecast. The crowd situation is ‘sometimes’ so you might have some company, but for quality like this, it’s worth it.

Thursday 3 September rolls back into smaller, weaker surf with a moderate breeze, and the break is back to poor conditions by the afternoon.

From Friday 4 September through to the end of the first week, the swell drops right off. We’re talking tiny, weak waves with next to no energy. The wind is mostly cross-off but the swell is just not there. There’s a small window on Sunday 6 September morning with clean, offshore conditions and a little 1 ft wave, but it’s very ordinary.

The following week starts slow. Monday 7 and Tuesday morning 8 September have a bit of a pulse back, with Tuesday morning offering 4 ft from the SSE and a 13-second period, moderate energy (540), and clean conditions with a light breeze. It’s a solid option but not a standout.

After that, it’s back to flat and small for a long stretch. Wednesday 9 through Friday 11 September is all tiny, poor surf with strong winds and cross-onshore conditions. The combined energy stays in the double digits.

Saturday 12 September morning is a nice surprise. Glassy conditions again, with a 2 ft swell from the SSE and a long 16-second period, giving good shape. The energy is moderate (342). It’s a good, clean, small-wave session.

Sunday 13 September is a big one for the experienced crew. The morning brings a 10 ft swell from the south, but it’s predicted to be too big for the break. The wind is light offshore, but that’s a lot of water moving. The afternoon settles down to a clean 6 ft from the SSE with a 14-second period, strong energy (1168), and good conditions. Another solid option.

The last few days of the forecast, from Monday 14 to Tuesday 15 September, taper off quickly into small, onshore, poor surf again.

So, to wrap it up: the best bet on offer is hands-down Wednesday 2 September afternoon at Sponge Bay. Glassy, long-period groundswell, and chest-to-head high waves. That’s the one to circle on the calendar. The Tuesday morning of the same day is also a clean option, and the Sunday morning of the 13th is for the big-wave hunters only.

Keep your eyes on the forecast, but for now, I’m calling it.

Rusty.
