Sponge bay Surf Forecast and Surf Report

G’day, it’s Rusty here. Let’s have a look at the next couple of weeks for Sponge Bay. First up, I’ll be honest with you: the start of this window is a bit of a write-off. We’ve got a few days of small, messy waves and the wind’s just not playing ball. The first real chance of anything decent doesn’t show up until Saturday the 15th, so if you’re keen, that’s your target.

The early part of the week is pretty grim. Monday the 10th has a tiny 2ft southeast swell, but it’s just not doing anything for the bay. The energy is weak (94). Tuesday the 11th sees a bit more swell, 5ft, but it’s coming from the southwest with a short 8-second period and onshore wind, making it a complete mess. The energy picks up to moderate (436), but the quality is poor. Wednesday the 12th and Thursday the 13th are similar – small, weak swells with clean conditions at times, but just not enough to get excited about. We’re talking 3ft surf with energy in the low hundreds (130, 187). It’s a waiting game.

Friday the 14th is a write-off with strong winds and rain, so don’t even bother. Then we get to the standout of the whole period: Saturday afternoon, the 15th of August. The wind goes glassy, and that southeast swell jumps to 8ft with a strong 1341 energy. This is the one to circle on the calendar. It’s pushing into the eight-foot mark, so it’s only going to suit experienced surfers, but the conditions will be excellent. This is the pick of the bunch for the whole window. The morning of the 15th is also not bad, with 5ft and clean offshore winds, but the afternoon is the real deal.

After that, the swell stays big but the wind turns against us. Sunday the 16th and Monday the 17th see solid, powerful swell – up to 11ft from the south-southeast with very strong energy (3620, 2767) – but it’s accompanied by strong onshore winds, making it blown-out and dangerous. Not a paddle. The beginning of the following week, from Tuesday the 18th through Thursday the 20th, the swell remains huge, around 10ft to 11ft. The energy is very strong (well over 3000), but it’s just too big for this break and the wind is still not ideal. The comments say it’s too big for the break, and I’d agree. It’s not for the faint-hearted, and likely only any use for the most experienced, and even then, the conditions are marginal.

Finally, we get a drop in size late in the window. Friday the 21st has 6ft swell, but the wind is messy. But then Saturday the 22nd of August looks promising. The swell is a clean 5ft from the east-southeast with a long 12-second period, and the morning has light cross-offshore winds. This is a proper groundswell, and it should offer some nice, well-shaped waves. The energy is moderate (845), but it’s clean. That’s your second standout.

Sunday the 23rd and Monday the 24th ease off to a more manageable 4ft and 3ft with clean conditions, a good time for the beginners to get out there. The water temp is pretty much average for this time of year, so nothing extreme to worry about. The window ends on Tuesday the 25th with the swell fading out completely.

So, bottom line: the first few days are a bust. The two days to really go for are Saturday the 15th for the big, glassy expert session, and Saturday the 22nd for a cleaner, more moderate swell. The rest is either too small, too messy, or too big. Keep an eye on that forecast, though, because things can change.

Rusty.
