The Lowdown
Alright, let’s lay it out plain. This is a grim 16-day outlook for Halfpoint/Fullpoint. From right now all the way through the end, there’s not one session I’d call worth paddling out for. It’s a solid block of poor conditions with no standout.
Monday the 24th kicks off with a 5ft ENE swell, short period at 7 seconds, and a strong 25 mph cross-shore wind. You’re looking at messy cross-chop. Water temp is 81°, nothing unusual for this time of year. Monday afternoon, Tuesday, Wednesday – same story: swell between 5ft and 7ft, that ENE wind blowing 20-25 mph cross-shore or cross-on. Wave energy is moderate, reaching 643 by Tuesday, but with that wind, it’s just lumpy and blown out.
Thursday the 27th brings some S swell, long period at 17 seconds, combined energy up at 878, but again, fresh cross-shore wind ruins any chance of clean shape. That long-period groundswell needs clean air, and it isn’t getting it. Friday, Saturday, Sunday, and into Monday the 31st keep the same frustrating pattern. Swell hits 7ft on Monday morning with 710 energy, but it’s still cross-shore wind.
September 1st gives the strongest energy of the whole stretch – 1042 on Tuesday morning with a 7ft ENE swell. That is serious power. But the wind is a fresh 22 mph cross-shore. For a spot that’s exposed to the ESE, the swell direction is off and the wind is never your friend. This setup looks far more interesting for kite surfing than for a clean paddle session. That’s just the truth.
From September 4th onward, the swell drops a little but the wind stays cross or onshore. By Saturday the 5th, we get a brief SSW long-period groundswell up to 20 seconds – could be a dream – but it’s cross-on at 22 mph and lumpy. The second week is more of the same: messy and bumpy.
So there’s nothing good on offer here. If this area is often like this when the pattern locks in, you just gotta wait. Forecasts can change, but right now I’d save the gas.

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.

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.
