The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s on offer at Halfpoint/Fullpoint over the next couple of weeks. Straight up, I’ve got to be honest with you—this isn’t a pretty picture. The whole 16-day window is basically a write-off for quality waves. The wind is relentless, blowing from the ENE or NE almost every session, and it’s almost always cross-shore or cross-onshore, churning the ocean into a lumpy, choppy mess. There’s no glassy morning, no offshore breeze to clean things up—just raw, messy conditions.
The first proper surf recommendation comes in on Saturday, August 8, but I wouldn’t bother paddling out. The swell is small at 5 ft from the ENE with a short period of 6 seconds, and the combined energy is weak (274). The wind is a fresh 22 mph cross-shore, making it lumpy and poor. Same story for the rest of that weekend and into Monday (August 10)—swell bumps up to 5 ft, but the period stays short (7–8 seconds), and the wind stays fresh and cross-shore. The energy climbs to moderate (559), but the surf quality is still rated as poor.
There’s a bit of a change mid-week. On Wednesday, August 12, the swell drops to 3 ft but comes from the south with a very long period of 18 seconds—that’s proper groundswell energy. The combined energy hits 909 (moderate), but the wind is still a fresh 22 mph cross-shore. A long period swell like this wants a point break or reef to wrap around, not a wind-blown beach setup. The cross-chop just ruins it.
Thursday, August 13, sees the swell hold around 4–4 ft from the south with a 15–16 second period, and the energy is strong (1054). But the wind picks up to 25 mph from the NE, a strong breeze that’s cross-shore and messy. Then things get wild. Friday, August 14, the swell jumps to 8 ft in the morning and 10 ft in the afternoon from the ENE, with a short 8-second period, and the wind becomes a near gale at 31 mph. That’s a lot of water moving (energy at 1349–1481), but it’s a total washing machine. For the more experienced surfers, this is a handful—but it’s not clean, and the cross-shore wind makes it a battle. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
The weekend of August 15–16 is a big one. Saturday morning sees 13 ft ENE swell with a 9-second period, and the energy is very strong (2816–3293). The wind is a strong 25–28 mph cross-shore or cross-onshore. This is expert territory only—over 8 ft and messy. Sunday (August 16) brings 10 ft from the south with a 12-second period, again strong energy (3848), but the wind is still a strong cross-shore. Not good.
After that, things settle down a bit but never get good. From Monday, August 17, through to Sunday, August 23, the swell drops back to 1 ft–5 ft, mostly ENE with short periods, and the wind remains a fresh to moderate breeze, always cross-shore or cross-onshore. The energy drops to weak to moderate (220–473). There’s one tiny window on Wednesday, August 19 afternoon, with a 1 ft SSW very long period swell (16 seconds), but it’s still cross-shore and choppy.
The water temperature anomaly is average for the time of year, so no surprises there.
The bottom line: there’s no standout session in this whole forecast. The wind is the enemy—it never lets up. If you’re desperate, the Wednesday, August 12 morning has the best potential with that 3 ft south groundswell at 18 seconds, but don’t expect it to be clean. The cross-shore wind will still be a factor, and the break is exposed, so it’s a gamble. If you’re a beginner, steer clear of anything above 5 ft—and most of the window is above that, or the wind is too strong. Honestly, it’s a blank run for the area. It tends not to stay this poor for long, so keep an eye on the forecasts—things can change.

Information about the Halfpoint/Fullpoint Surf forecast
The above surf forecast table for Halfpoint/Fullpoint provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Halfpoint/Fullpoint can be found by selecting the local surf guide option on the grey menu. Our Halfpoint/Fullpoint surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Halfpoint/Fullpoint) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Halfpoint/Fullpoint 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
