The Lowdown
Alright folks, Rusty here. Gotta keep it real with you on this one. The next sixteen days are looking like a real battle against the wind. We've got some size at times, but the conditions are rarely lining up for a quality paddle. The whole run is plagued by strong cross and cross-onshore winds, which is making a mess of what could be decent waves. There are no standout winners here, so we're just looking for the least worst option.
Let's start with what we've got. The forecast kicks off with a bit of a dud.
Tuesday the 25th into the weekend, we've got wind, wind, and more wind. Easterly winds are howling at 25 mph, creating super choppy, messy surf. The swell height sits around 5 ft to 6 ft, but the cross-shore chop makes it basically unrideable. The water temp is sitting at a toasty 81°, which is pretty average for this time of year, so at least you won't freeze waiting for a clean one.
The only spot on the map is Halfpoint/Fullpoint. It's an exposed, fairly consistent intermediate spot that loves an ESE swell. The problem is, we're getting a lot of easterly and ENE swell with periods mostly under 8 seconds – that's weak, wind-swell. The wave energy is mostly moderate, with readings like 586 on Tuesday morning, bumping up to 861 by Thursday the 27th, but all that energy is just creating a lumpy, cross-chop mess.
The pattern of fresh cross-shore wind and messy waves just keeps repeating. Swell sizes bounce around, but the wind never gives us a break.
We hit Saturday the 5th of September and things get interesting from a size perspective, but not from a quality one. The swell jumps to 6 ft from the ENE with a period of 13 seconds. The combined energy skyrockets to 1264, which is strong wave energy. It's got some grunt. But again, the wind is a solid cross-shore at 19 mph, making it lumpy. It's only a 1 out of 10, described as "marginal". For a confident intermediate to expert surfer, it might be worth a look if you're desperate, but the wind will make it tough.
Sunday the 6th and Monday the 7th keep the same frustrating story. The swell holds around 6 ft with a 13-second period, and the energy is even higher at 1454, yet it's all ruined by that ENE wind hammering cross-shore at 25 mph. The water gets churned into a mess. At this point, the exposed beach setup with this much cross-wind and chop is looking more like a kite surfer's playground than a paddle surfer's dream.
To be honest, across the entire sixteen-day run, there is no single period I can point to and say "that's your window." It's all a variation on the same theme of poor surf conditions thanks to persistent easterly winds. You'd be flogging a dead horse out there most days.
Hang in there. Forecasts can change, but right now, it's a blank run for clean waves.
Rusty.

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.
