Sponge bay Surf Forecast and Surf Report

Alright, this is Rusty comin’ at ya with a look at what’s on the cards for Sponge Bay over the next couple of weeks. We’re looking at a beach and reef setup here, fairly exposed to a SSE swell. Water temps are about average for this time of year, nothin’ weird going on.

Right off the bat, this Tuesday morning is actually not too bad. We’ve got a clean 3ft wave from the SSE with a period of 11 seconds – that’s a bit of groundswell in the mix, and light offshore winds from the north. Combined energy is 245 (moderate). It’s surfable, but it’s pretty ordinary. Not a standout, just a paddle to wet the suit. The afternoon turns messy with a cross-offshore breeze.

Wednesday and Thursday mornings offer small, clean waves – around 2ft to 3ft – with light offshore or cross-off winds. Still just ordinary conditions, but if you’re a beginner or just want a quiet session, it’s doable. Crowds are listed as “sometimes,” so you might have the place to yourself on these small days.

Friday and Saturday get a bit rugged. Friday brings onshore gunk, and Saturday serves up a lumpy, cross-onshore 6ft swell with short, weak period. Not worth gettin’ out of bed for.

Now here’s where it gets interesting. Monday the 21st of September: clear skies, light offshore breeze from the NNW, and a clean 4ft wave from the SSE with a 12-second period. Combined energy jumps to 861 (moderate to strong). That’s a proper session on the cards. The same afternoon sees a 5ft wave with a very long 17-second period from the SSE, energy hitting 1406 (strong). That’s groundswell rippin’ into the bay. The wind goes cross-shore in the arvo, creating a bit of chop, but the morning is the pick. This is the first true standout.

But the cream of the crop looks like Monday the 28th of September. A clean 7ft to 7ft wave from the south, period at 8 seconds. The morning sees cross-offshore winds, but the afternoon? Glassy conditions with the SSW wind dropping to almost nothing. Combined energy around 895 to 1110 (strong). This is expert territory at 6ft+ and the southerly swell is a good fit for the break. This is your best shot at a glassy, powerful session. Definitely one to circle on the calendar, though it’s a long way out.

Between those two standouts, there’s a fair bit of junk. Friday the 25th through Sunday the 27th are all cross-onshore or messy, with poor conditions. That stretch is about three days of nothin’ to write home about.

Also, on Wednesday the 30th of September, there’s a promising clean 4ft wave with a very long 16-second period from the SSE. Energy is 750 (moderate to strong). That’s another potential session if the forecast holds. The longer period suits a point or reef, and Sponge Bay is a beach and reef mix, so expect it to hold up nicely.

Early on, the 2ft to 2ft days around the 27th are barely worth mentioning – just a splash around.

So, bottom line: grab Monday the 21st morning, and do not miss Monday the 28th afternoon if you’re an experienced surfer lookin’ for a glassy, solid wave. The rest is small or messy.

Rusty.
