The Lowdown
Alright, Rusty here. Let's have a look at what's on offer at Halfpoint/Fullpoint.
So here's the deal: the next couple of weeks are looking pretty grim. We've got a lot of wind and not much in the way of clean, rideable surf. The water temp is sitting at a pretty normal 81°F, so no surprises there, but the wind is just relentless. For the first ten days or so, from Sunday the 23rd of August right through to the start of September, it's a write-off. The swell is there, but it's coming in with a short, weak period of 7 seconds and a messy cross-shore wind that's just chopping everything up. The combined energy is moderate but that wind ruins it. Don't even bother.
There is a long, blank stretch here. Nothing worth paddling out for until we get into the first week of September. The wind doesn't let up, and the swell direction shifts around but never lines up right.
Now, keep your eyes on Monday the 7th of September. That morning, things finally change. We're looking at a cleaner setup with a light breeze from the NNE, which is cross-offshore and will leave the surface glassy. The swell will be a solid 6ft from the ENE with a period of 10 seconds, so it'll have some good energy behind it. This is the clear standout of the whole forecast period. It won't be too big for most intermediate surfers, but the wind will make it genuinely enjoyable. Just be aware that with a 10-second period, it won't be a heavy groundswell, but it'll be a fun, punchy wave. And since this break is fairly consistent and exposed to the swell, it should be working. Crowds are listed as "often" here, so expect some company.
The afternoon of the 7th is still workable with a gentle breeze and 5ft swell, but that morning window is the one to lock in.
There's a bit of a tease on Saturday the 5th of September, with some bigger swell (7ft) and a longer 11-second period, but the wind is still cross-shore and moderate, leaving it choppy. It's a maybe, but not the pick.
So to sum it up: the first week and a half is a total loss. Don't waste your time until Monday the 7th of September. That morning is the one.
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.

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.
