Sponge bay Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks. We’ve only got one spot on the cards, so let’s dive into Sponge Bay.

The next 16 days start with a bit of a flat spell. The first proper surf we’d even talk about is on the 24th of August, but honestly, it’s pretty weak sauce that morning – small 3ft SSE swell, light cross-off wind out of the NW. The water’s sitting a bit colder than normal for this time of year, about 54°, roughly 3° cooler. That 24th afternoon and the 25th don’t do much to get the heart pumping either, with tiny waves and ordinary conditions.

Now, the first real stand-out starts shaping up on the morning of the 26th of August. Clear skies, light NW cross-off breeze, and a clean little 2ft SSE swell with a beautiful long period of 17 seconds. That’s a proper groundswell, giving it shape and push, and the combined energy is moderate at 359. It’s only small, but the conditions will be clean for a beginner-friendly beach and reef setup.

Hold onto your boardies though, because Thursday the 27th of August afternoon is the highlight of the whole run. We get a jump to 5ft SSE swell with an 18-second period – that’s some serious long-period energy pushing in. The wind is a light cross-off out of the ENE, and the combined energy hits strong at 1177. This is the one to circle on the calendar. Clean, well-shaped, and a damn sight better than anything else.

The 28th of August (Friday) keeps the fun going with offshore NNW winds, 12 mph, keeping the 4ft SSE swell tidy. Good conditions both morning and afternoon. Then it tails off into a bit of a lull over the weekend and start of the following week, with small wave heights and ordinary scores.

There’s a bit of a spike on the 31st of August, Monday morning – a 8ft SSW swell rolls in, but the period is only 9 seconds, so it’s a windswell, not the cleanest shape. Combined energy is strong at 1027. That size is edging into expert territory for a smaller, beginner-friendly setup. It might be a bit of a washing machine unless you’re keen on a challenge. That afternoon drops down to 4ft SSE and it’s more manageable but still decent.

The first week of September looks average to marginal, with plenty of cross-off winds but swell staying under 5ft. The period drops, and the conditions get a bit mixed. Nothing worth getting up at sparrow’s for. The longest gap of poor-to-ordinary surf runs from the 1st of September afternoon through to the morning of the 5th.

So, bottom line: If you can only paddle out once, make it the afternoon of Thursday, 27th August. Second choice would be the Friday the 28th morning. Everything else is either too small, too onshore, or just ordinary.

Stay stoked.
Rusty.
