The Lowdown
Alright, Rusty here again. Let’s talk about Halfpoint/Fullpoint, and I’m not gonna sugarcoat it – this 16-day window starts real rough.
First eight days, from Sunday the 6th right through, there’s basically nothing worth paddling for. The wind is a mess – fresh cross-onshore, lumpy chop. The swell is there, with some 7ft to 8ft of ENE groundswell (period 12 seconds), combined energy moderate to strong (1951 to 2233), but the wind has it torn to pieces. It’s just not surfable.
Wednesday the 9th offers a tiny glimmer – a small SSW swell (3ft to 3ft) with a long period (13 to 14 seconds), combined energy moderate (526), but the wind is still light to moderate cross-onshore. It’s marginal at best.
Then from Thursday the 10th through to Wednesday the 16th, it’s poor. Short-period ENE windswell, fresh cross-shore wind – just messy. Wave heights 4ft to 6ft, but not clean.
The only real standout is the second week, starting Thursday the 17th. A long-period SSW groundswell arrives with periods of 15 to 18 seconds – that’s very long-period. The waves are small (2ft to 4ft), but combined energy is moderate to strong (547 to 773). The wind is cross-shore and fresh, not ideal, but this is a point break, which is where you want that long groundswell. It’s not a big day, but the quality will be there if you pick your moment.
Sunday the 20th to Monday the 21st looks similar – small SSW groundswell (3ft to 4ft), long period, fresh cross-shore wind. Still the best on offer.
Overall, a tough first week, then a small but promising groundswell window in the second week. Keep an eye on it, but don’t expect much until then. Rusty out.

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.
