The Lowdown
G’day, Rusty here with the imperial heads-up. Look, I won’t sugarcoat it – this 16-day stretch for Halfpoint/Fullpoint is mostly a rough go. There’s plenty of swell energy, but the wind’s all cross or onshore for days on end. Only a couple of windows offer any real hope, so let’s walk through it.
The run starts off ugly from Monday 31 August through Friday 4 September. Swell hangs between 7ft and 8ft from the ENE, but it’s a short, messy 8-second period, so the waves are choppy and weak in shape. Wind is screaming at 22 to 28 mph cross or cross-onshore, making it lumpy and horrible. The combined wave energy is moderate to strong (743 to 1680 on Friday morning), but with that wind, it’s a waste. Water temp is 80°F, pretty normal for the season.
On Saturday 5 September into Sunday 6 September, the swell period jumps to 13 seconds – that’s real groundswell energy – with size still at 8ft to 8ft from the ENE. The combined energy peaks at 2458 Saturday morning, so there’s serious power. But wind remains a fresh 19 to 22 mph cross-shore, and it’s only “marginal” at best. With size pushing over 8ft, it’s strictly expert territory, and the ENE direction isn’t the preferred ESE, so the break might not handle it well. Hard pass for most.
Here’s your one true highlight. On Monday 7 September in the afternoon, the wind finally cleans up to a light 9 mph from the north, going cross-offshore, and the report says “clean.” Swell is still a solid 8ft from the ENE with an 11-second period, and the energy is strong at 1872. This is your session. The waves will have shape and power. Crowds are often here, so you’ll have company, but for a clean afternoon with that much grunt, it’s the best on offer. That size is for strong intermediates and up, though – not a beginner’s wave.
Tuesday 8 September switches to a tiny, long-period SSW groundswell (3ft to 4ft, 14-15 seconds) but with light cross-onshore wind, so it’s a bit messy. Energy is weak to moderate (735-842). Maybe a longboard option, but nothing special.
From Wednesday 9 September, we’re back to short-period ENE junk (6ft to 7ft, 8 seconds) with relentless cross and cross-onshore winds from 12 to 28 mph. Energy drops from 1021 down to 257 by Friday 11 September afternoon. Poor, lumpy conditions. This flat, windy pattern continues right through the weekend and into the next week.
By Sunday 13 September, the swell crashes to a tiny 2ft from the SSW with a long 15-second period, but wind is still cross-on or cross-shore from the ENE, and energy is very weak (242-278). Monday 14 September and Tuesday 15 September are more of the same – small, weak, and wind-affected. No quality in sight for that second week.
Bottom line: the only real standout is Monday 7 September afternoon. That cross-offshore wind and solid groundswell could give you some fantastic waves. The rest of the 16 days? I’d wait for a better forecast. Things can always change, but right now it’s a long dry spell.

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.
