Sponge bay Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s on offer for Sponge Bay.

The next couple of weeks are a bit of a mixed bag, to be honest. We’ve got a decent pulse of energy coming through, but finding clean surf is going to take some patience. The water's sitting at 55°, which is a touch colder than what we’d normally expect this time of year – about 2° off, so definitely feel that chill in the morning.

Our only real standout window kicks off Thursday the 3rd of September. That morning, we’ve got a solid 4ft SSE swell with a long 13-second period, packing moderate energy (506). The wind is a clean cross-off from the NW, so Sponge Bay should be offering up some pretty lined-up, workable waves. It’s a beach and reef setup, fairly consistent, so you’ll get plenty of chances. The afternoon cleans up even more, with a 3ft SSE swell and the wind backing off to a gentle breeze. The energy drops a notch (318) but it’s still a lovely afternoon session.

Friday the 4th sees the swell drop out fast. We’re down to 2ft and shorter period, not really enough to get excited about. The whole weekend and into the start of the next week is pretty flat or messy, with most of it rated poor. There’s a brief teaser on Tuesday the 8th of September – a 4ft SSE swell with an offshore breeze from the N, creating clean conditions. The energy is moderate (258), and the waves are surfable, but nothing to write home about.

The real spike comes late in the second week. Around Sunday the 13th of September, we see a massive jump to 16ft from the SSW, with a very long 14-second period and crazy high energy (13943). But here’s the kicker – it’s accompanied by a strong cross-onshore wind that will turn that place into a washing machine. That’s big, powerful, and messy, not one for the paddle crew. It might look interesting for kite surfing, though. If you’re an expert looking for a battle, maybe, but don’t expect any clean faces.

After that, Monday the 14th of September morning brings a more manageable 5ft SSE groundswell (13s period, 877 energy) with light offshore winds from the WNW. That could be the pick of the week for a morning paddle – clean, some nice lines, and not too heavy. It does start to deteriorate in the afternoon as the wind swings onshore.

Overall, your best bet is Thursday the 3rd for a solid, clean session. The long-range Monday the 14th is promising but less certain this far out. Crowds are possible at Sponge Bay – it’s a spot that can get busy when it’s good. For the rest, there’s a lot of waiting around.

Stay patient, keep an eye on the wind shifts.
Rusty.
