The Lowdown

Alright, mate, Rusty here. Let’s be straight with you—this stretch is looking pretty grim for the next couple of weeks. We’ve got a solid 16-day window ahead, but honestly, there’s barely a moment worth paddling out for. The water temp at Whitesand Bay is hanging around average for the time of year, so at least you won’t be freezing while you’re staring at flat, bumpy lines.

We kick off on Thursday the 27th of August with tiny, gutless surf. Morning shows a weak 0.7 ft swell from the west with a short 7-second period, and even though the wind is light offshore from the ESE, it’s just not enough to get excited about. The combined energy is a measly 8—barely a ripple. Afternoon gets even worse with a 0.3 ft, 12-second period swell, but it’s cross-onshore and choppy. Not happening.

Friday the 28th brings a slight bump, with morning swell of 4 ft from the SW at 6 seconds, but the wind is onshore from the west at 9 mph, and the energy is 217—still weak and poor quality. Afternoon is similar with 4 ft, choppy cross-onshore wind. Nothing clean.

Saturday the 29th sees a bit more size, 6 ft in the morning from the SW, but a fresh 22 mph cross-shore wind from the SSW makes it lumpy and messy. The energy is 323—moderate, but the conditions are rubbish. Afternoon drops to 7 ft with a 16 mph onshore wind from the west. Still poor.

Sunday the 30th has 5 ft in the morning, cross-onshore, choppy. Afternoon drops to 3 ft with cross-shore wind. Not worth it.

Monday the 31st offers 5 ft in the morning, cross-onshore, choppy. Afternoon has 5 ft with onshore wind, but the period stretches to 10 seconds, and the energy is 370—moderate. Still, the wind kills it.

Then we hit a real dry spell. From Tuesday the 1st of September through to Sunday the 7th, it’s a mix of weak swell, strong winds, and messy conditions. The energy dips into the double digits for a few days, and the wind is often strong or gale-force. The 5th of September has a near gale cross-onshore wind at 31 mph with 7 ft swell—that’s kite-surfing territory, not paddle surfing.

Monday the 7th of September has a bit of hope: 7 ft from the west at 7 seconds with a gentle cross-shore wind from the NNW, energy hitting 485. Still, the wave comment says “poor surf conditions.” The afternoon is marginal at best, with 6 ft and light wind, but it’s cross-onshore and weak.

The rest of the outlook through to the 11th of September is a mix of small, weak swell and strong, lumpy winds. The 11th of September morning shows a big 10 ft swell from the WSW at 8 seconds, with a combined energy of 1098—strong! But it’s marginal, with a moderate cross-shore wind, and the period is short, so it’ll be a messy, heaving shore break. Only for experts, and even then, it’s a gamble.

Honestly, there’s no standout session here. The whole 16-day window is a bust for clean, rideable waves. If you’re desperate, keep an eye on the 7th of September morning for a chance at something, but don’t hold your breath.

Rusty.

Further information to help with frequently asked questions about our surf forecast for Whitesand Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
