The Lowdown
Alright, Rusty here, let’s talk about what’s on the cards for Halfpoint/Fullpoint.
Right now, it’s a bit of a rough stretch. The forecast kicks off on Sunday the 30th of August, but there’s no real surf to get excited about for a while. We’re looking at a solid block of days with poor conditions – the wind is howling out of the east-northeast at 25 mph, and it’s coming straight across the wave faces. We’ve got a messy cross-chop that’s ruining any chance of a clean wave. The swell is sitting around 6 ft, coming from the ENE with a short period of only 7 seconds, so it’s just a jumbled, weak energy. The water temp is a warm 81°F with a normal anomaly, so that’s fine, but the wind is just killing it.
Through the first week of September, the story doesn’t change much. The wind stays strong, mostly cross-shore or cross-onshore, and the swell is either too short-period or way too big, all while the wind trashes the surface. The combined energy climbs into the 900s and then spikes hard on the 3rd, but with a near gale blowing at 31 mph, that’s just a washing machine. By the 4th and 5th, we’re seeing swell heights of 12 ft, but the wind is still strong and cross-onshore, so it’s all blown out. There’s a brief moment on the 5th afternoon where the period jumps to 13 seconds, and the energy is massive, but with a fresh cross-onshore wind, it’s just not surfable.
Then we hit Sunday the 6th of September. The swell is still solid, about 7 ft, and the period is a nice long 13 seconds, so there’s some real energy. The wind is still a fresh cross-shore, leaving a lumpy surface, but it’s a step up from the days before. It’s only a marginal forecast, though, so not a goer.
The real standout happens later. Tuesday the 8th of September morning is looking like the best in the window. The swell is 15 ft from the east with a 12-second period – that’s a massive, powerful groundswell. The wind is a fresh cross-offshore breeze from the north-northeast, which means the waves are going to be clean. But here’s the catch: that swell is too big for Halfpoint/Fullpoint. This is only for experts, full stop. If you’re a solid surfer, the morning session will be firing, but you’ll need to know what you’re doing. The crowd is bound to be there too, as it’s often busy.
The next day, Wednesday the 9th, is also promising. The swell is still a heavy 10 ft from the east-northeast (9-second period), and the wind drops to a slight air, only 3 mph, with a light cross-shore. That’s glassy, clean conditions. Again, it’s too big for this break unless you’re an expert, but the quality is there.
After that, it drops off again. From the 10th through the 14th, we’re back to poor conditions: light winds but onshore or cross-shore, with a short-period 8-second swell and low energy. The waves are small, messy, and not worth paddling out for.
Bottom line: The first week and a half is a write-off. The one true standout is Tuesday the 8th of September – huge, clean swell but only for experienced surfers. The 9th is also a good, clean option for the same crew. If you’re not an expert, wait for the next forecast.
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.
