The Lowdown
Alright, let’s talk about Halfpoint/Fullpoint. The forecast covers the next 16 days, but honestly, mate, it’s a rough stretch. There’s a long gap of nothing worth paddling out for right from the start. The first proper surf recommendations don’t kick in until mid-August, and even then it’s a real mixed bag.
The water temp is sitting at about 80°, which is pretty normal for this time of year, so at least you won’t need a thick wetsuit.
The first standout that might get your attention is around Friday the 14th of August. By the afternoon, we’re looking at a 8 ft swell coming out of the ENE, with a period of 8 seconds. That’s a fair bit of size—definitely expert territory—and the combined energy is strong at 1101. The wind is cross-shore, fresh, and lumpy, so it won’t be glassy, but it’s the only window where the surf is borderline decent. The swell direction is ENE, which is close to the optimal ESE, so it’s on the right side of the compass.
The next possible highlight is Saturday the 15th of August, with a similar 8 ft ENE swell, but the wind is stronger—25 mph cross-shore and messy. The energy is still high at 858, but conditions are chopped up. It’s really only for the die-hards.
After that, the surf drops off quickly. The energy and size fade, and the wind stays cross or cross-on, lumpy, and choppy. There’s a brief window on Tuesday the 18th of August with lighter winds, but the swell is small and weak.
Honestly, mate, this is not a time to be fussy. If you’re an expert and you’ve got a big board, the 14th and 15th might offer some punchy, messy waves, but for anyone else, it’s a tough run. The break is fairly consistent, so it’s not a total write-off, but the conditions are just fighting against you.

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.
