The Lowdown
Alright, Rusty here again, but we're doing this in feet and miles.
Let’s cut straight to it for Halfpoint/Fullpoint.
It’s a grim start, no two ways about it. We’re looking at a real dry spell from Friday the 28th of August through to the 6th of September. That’s a full ten days where you’re better off doing something else. The issue is relentless, strong cross-shore and cross-onshore winds out of the ENE at 18 to 25 mph. It’s tearing up any hope of a clean wave. The swell does fill in – we see it hit around 6 to 7 ft by the end of August – but the wind just has it all lumpy and cross-chopped. The wave energy is moderate to strong, hitting around 745 and even 959 on the 1st of September, but with that wind, it’s a mess. Not worth your time.
Okay, so after that long lull, the morning of Monday the 7th of September shows a spark. Swell runs about 8 ft from the ENE with a long period of 11 seconds, pushing the combined energy up to a strong 1590. The wind is still a cross-shore from the NE at 18 mph, so it’s not perfect, but it’s a fresher breeze. It’s a marginal call, and with the swell at 8 ft, this is really only for experienced surfers. Beginners will be out of their depth. The afternoon is a washout with bigger 8 ft swell and more wind.
Mark this one: Wednesday the 9th of September in the afternoon. We get a big 10 ft swell from the ENE, with combined energy of 1148 – that’s very strong. The wind looks better, with a moderate breeze from the NE at 12 mph in the morning and a fresh 18 mph in the afternoon. But the word is, this is predicted to be too big for this break. At 10 ft, this is expert territory only. If you’ve got the skills and the big-wave board, it’s your day. If not, it’s a spectator sport.
Then, on the morning of the 11th of September, we get another look. The swell drops to a manageable 6 ft from the ENE, and the wind finally plays ball, coming light from the SW at only 6 mph. That’s the cleanest wind of the whole outlook. The combined energy is moderate at 712. It’s not a huge day, but for intermediates wanting a clean session without the heavy stuff, this is your best bet.
So, the long and short of it: over a week of nothing. The only real highlights are the big, expert-only swell on the 9th of September, and the smaller, cleaner window on the morning of the 11th of September. The rest is blown out. Keep that Wednesday in mind.
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. 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. If you surf the same spot (Halfpoint/Fullpoint) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
