The Lowdown
Alright, Rusty here. Let's talk about what's on the cards for Halfpoint/Fullpoint. Looking at the whole 16-day window, I gotta be straight with you – it’s a tough stretch. A whole lot of cross-shore wind and messy conditions dominate the first half. Keep your expectations in check.
We kick off on Saturday the 22nd of August, and the news ain’t good. We’ve got a strong ENE breeze hitting 25 mph, blowing straight cross-shore. There’s a bit of swell, around 5 feet coming from the ENE, but with a short, weak period of only 7 seconds and combined energy readings that start weak and only get to moderate (245-333), it’s all just lumpy, chopped-up slop. This pattern of fresh to strong ENE cross-shore wind and tiny, poor-quality swell sticks with us right through the week. The water temperature is sitting at 80°, which is pretty average for this time of year.
The whole first week and into the start of September is basically a write-off. The swell that does appear is mostly weak and short-period, and that constant ENE wind just won't let up. On the 26th of August, we see a brief change with a very long-period south swell (18 seconds) coming in, but it’s only 2 feet and the wind is still a fresh cross-shore. The energy is moderate (626), but the conditions are still poor. We get a few more days of this frustrating S and E swell with the same relentless cross-shore breeze. It’s a 9-day gap of zero recommendations here.
The one true standout – and honestly, the only time to even think about paddling out – is the afternoon of Wednesday the 2nd of September. The wind drops right out. We get a glassy surface with a light breeze from the ENE at only 3 mph. The swell is a clean 3 feet from the south with a very nice, long period of 16 seconds. The combined energy is a solid moderate (570). For an intermediate level break, that's some proper groundswell hitting the point. Because it’s glassy, the waves should be clean and lined up. I’d say that afternoon is the pick of the entire forecast.
After that brief moment of glory, we slide back into marginal conditions on the 3rd. Then, heading into Saturday the 5th and Sunday the 6th of September, the swell starts to get serious. On the Saturday afternoon, we’ve got a 6 feet swell from the east with a long 16-second period and very strong energy (2133). But the wind is a moderate cross-shore. Then on Sunday the 6th, we see the biggest swell of the forecast: a 10 feet groundswell from the ENE with a 14-second period and incredibly strong energy (3652). That is a lot of water. The forecast notes the wind and tide are favorable, but that size is too big for this break. This is strictly expert territory at Halfpoint/Fullpoint, and even then, that size with a 14-second period can be tricky. Setup looks more interesting for a tow-in or just watching from the cliff.
So to wrap it up: don’t waste your petrol for the next week and a half. Mark your calendar for the afternoon of Wednesday the 2nd of September for a chance at some glassy, clean south swell. Everything after that gets too big to handle.
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.
