Sponge bay Surf Forecast and Surf Report

Alright, let’s have a proper look at what’s heading our way for Sponge Bay over the next couple of weeks.

The water’s sitting at 56°, which is a bit colder than normal for this time of year – nothing too wild, but you’ll want a decent wetsuit.

Right now, it’s pretty grim. Thursday the 6th has a solid 10 ft S swell pumping in but it’s crossed up on a WSW wind and the energy is cranking at 3532 – that’s serious power, but the conditions are just poor. You’d be mad to paddle out. The setup here is beach and reef, and with that much swell and onshore wind, it’s honestly more interesting for kite surfing than paddle surfing.

Friday morning the 7th is where it starts to turn. Swell drops to 5 ft from the SE with a 10-second period and a clean cross-off NW breeze. The energy is moderate at 895 and the wave comment says “expect very good surf conditions.” This is the first real standout. It’s not huge, but it’ll be clean and well-shaped – a solid session for anyone.

Saturday morning the 8th follows up nicely: 4 ft from the SSE, 12-second period, light NW cross-off wind, glassy. Energy is 768. Again, clean, fun conditions. Not a standout, but a good solid option.

Sunday the 9th drops off a bit – 3 ft in the morning, light winds, but just small. The afternoon has a 2 ft swell with a long 14-second period, which is a groundswell. At Sponge Bay (beach and reef), that kind of long period can make things a little too straight, but it’ll be clean.

Monday the 10th through to Thursday the 13th is a real dry spell. Swells barely reach 2 ft and mostly drop to 0.7-1 ft. The energy goes from 91 down to single digits. There’s a brief glassy moment on Tuesday morning the 11th with 2 ft SSE swell and glassy wind – surfable but ordinary. Not worth getting excited about.

Friday the 14th and Saturday the 15th are tiny – think 0.3 ft to 0.7 ft – with some fresh breezes. Not happening.

Sunday the 16th stays flat with small 0.3 ft swell.

Now, Monday the 17th is a real standout. Monday morning brings a 6 ft SSW swell with a short 7-second period – so it’s a wind swell, but the wind is glassy from the WNW. Energy at 425 and the wave comment says “expect good surf conditions.” That’s a proper session for the experienced crew. For beginners, 6 ft is pushing it a bit.

Tuesday the 18th is another standout – morning has 7 ft from the SSE with a long 16-second period – that’s serious groundswell, energy cranking at 2116. But the wind is light and cross, so expect some lumps. At over 8 ft, this is expert territory only. That long period might make it wrap nicely, but at a spot like Sponge Bay, it could break a bit straight. Still, for the brave, there’s power.

From Wednesday the 19th onward, it goes downhill fast – onshore winds, rain, dropping swell. By Friday the 21st, it’s small and messy.

So, the best on offer: Friday morning the 7th – clean, fun, and solid – and Monday morning the 17th – glassy, punchy, and full of energy. The Tuesday the 18th is huge and powerful, but only for the experts.

Rusty.
