The Lowdown
Hey mates, Rusty here. Let me tell you, I’ve been through the numbers for Halfpoint/Fullpoint, and it’s a grim outlook. The whole 16 days are a tough slog. The wind is hammering in from the east-northeast day after day, blowing straight across the swell, which is exactly what you don’t want here. This spot needs clean, offshore northwesterlies to work, and we’re getting the opposite. It’s a place that usually holds some waves, but the conditions are just brutal.
Starting Friday the 14th of August, we’ve got a 7ft swell from the east-northeast with an 8-second period. There’s a heap of energy in the water (951), but that 22 mph cross-wind is killing it, leaving everything choppy and lumpy. It’s no good. That just gets worse over the weekend. Saturday the 15th sees the swell jump to 12ft with a near gale cross-shore at 31 mph – that’s dangerous, not surfable. The energy readings are through the roof at 1781 and 2504, meaning the ocean is absolutely churning, but it’s a mess. This is kite-surfing weather, not for a board and paddle.
The whole next week is more of the same. Swell sizes drop to between 2ft and 3ft, but the wind stays locked in from the east-northeast at 15-25 mph, keeping everything cross-shore and lumpy. You see a couple of longer-period south-southwest swells, like that 18-second one on Thursday the 20th, but with the cross-wind it’ll just break all straight and messy. The energy levels are moderate (110-606), but without clean wind, it’s all wasted.
There’s a couple of slightly less awful moments, like Sunday the 16th afternoon when the swell drops to 8ft and the wind backs off a hair, or Friday the 28th afternoon when the swell period stretches out a bit. But “marginal” is being generous. Don’t get your hopes up. We’re looking at a real dry spell here.
Forget about it for now. The water’s about typical for this time of year, so that’s not the issue. The ocean’s got plenty of power, but the wind is the boss, and it’s not playing nice. Wait for a change in the pattern.
Rusty.

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.
