The Lowdown
G’day, I’m Rusty. Let’s break down what’s cooking at Halfpoint/Fullpoint. Look, I’ll level with you—this 16-day forecast is pretty bleak. We’re staring down a massive gap from now until September 23rd with zero surf worth mentioning. Every day’s written off as poor surf conditions, with a constant cross or cross-onshore breeze, often blowing at 19 to 25 mph. That’s a long, quiet stretch.
This break is an exposed, fairly consistent intermediate spot that needs swell from the ESE. Water temp is around 81°, right on average for this time of year—nothing unusual.
The only chink of light comes Monday, September 23rd, in the morning. We see a swell bumping to 7 ft from the E, period of 10 seconds. The combined energy sits at 1666, so it’s got some grunt. Wind is cross-shore at 19 mph, but it’s still lumpy and messy. The report calls it “marginal” thanks to tricky tide conditions. That size is for experts only—if you’re not seasoned, stay on the beach. It’s not a true standout, just the only thing that rises above a completely poor run.
The rest of the period stays ugly. Constant cross-wind and lumpy chop kill the quality. With so much wind, this beach setup looks more interesting for kite surfing than paddle surfing.
Rusty.

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.
