The Lowdown
Alright, surfers, Rusty here with the long-range view for your local stretch.
Right off the bat, I gotta be straight with you – this forecast is a tough one. For the next couple of weeks, we are looking at a real flat spell with messy conditions. The wind is going to be a problem, mostly blowing across the swell from the ENE, and it's going to chop things up something fierce. We're looking at a long stretch of days where the surf just isn't worth paddling out for.
The first real chance we see of anything happening is a long way off. We've got a big gap of no good surf until we get to Tuesday, September 1st. On that Tuesday morning, Halfpoint/Fullpoint will see a bit of a pulse, with swell coming up to 7 ft from the ENE, but the period is a long 11 seconds. The energy is very strong, reading at 1506, but that wind is still a fresh cross-shore breeze, making it lumpy. It's a marginal call, but it's the best we've seen in a while. The afternoon is a little better on the swell front, with 8 ft from the east and a period of 13 seconds, which is a proper groundswell. The energy is huge at 2512, but it's still a cross-shore fresh breeze. It's an expert-only zone at that size, and the long period will make it peaky.
The real standout, if you can call it that, is Wednesday, September 2nd. That morning, the swell jumps to a solid 10 ft from the east with a 13-second period, and the energy is massive at 3014. This is a big, powerful groundswell. But – and it's a big but – the wind is a strong cross-shore breeze at 25 mph, creating messy, lumpy conditions. At 10 ft, this is strictly for the experts, and the wind is going to make it a real battle. It's not a pretty picture, but for size and power, this is the only real show in town.
So, what's the call? For the next week and a half, don't even bother. Save your energy. The best bet is to pencil in Tuesday, September 1st, and Wednesday, September 2nd for Halfpoint/Fullpoint, but only if you're an experienced surfer who doesn't mind working for it in messy, windy conditions. The water temp is about average for this time of year, so you won't need a thick suit.
Keep an eye on it, but don't get your hopes up too high.
Rusty.

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.
