The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window on the table for Halfpoint/Fullpoint, but honestly, it’s a bit of a slow burner. The first week is tough to watch – constant cross-shore winds and messy, lumpy conditions are the story at the start, and the surf quality is just poor. We’re looking at about a week of this before things start to get interesting.
The opening days from Sunday, August 9th through to Friday, August 14th are pretty much a write-off. The swell is a mix of short-period, wind-affected stuff from the ENE, with heights hanging around 5 ft to 6 ft, but because the wind is a fresh cross-shore (18 to 22 mph), the waves are just a bumpy, choppy mess. The combined wave energy sits between 425 and 886, which is moderate, but it’s all wasted energy given the wind. Not worth paddling out for.
Now, Saturday, August 15th sees the swell start to ramp up, with ENE swell hitting 8 ft and a period of 11 seconds. The energy jumps to 1532 (strong), but the wind is still a strong cross-shore at 25 mph, so it’s messy and very poorly organised. By Sunday, August 16th, we get a real spike – 10 ft swell from the ENE with a 13 second period, and the wind finally turns cross-offshore from the NNE at 18 mph. This is the first sign of clean conditions. The energy is huge at 4938, and the wave comment says wind and tide are favorable. However, the swell is a solid 10 ft, which is expert territory. This is a standout for the big wave crew, but it’s too big for beginners. The long period (13 seconds) means it’ll be a powerful groundswell, so point breaks or reefs would be better, but here at Halfpoint/Fullpoint, it’s exposed and will be a beast. This is the best single session on offer for the whole period, but it’s a heavy one.
After that, the window gets messy again. Monday, August 17th has a smaller 8 ft swell from the NE, but the wind swings to the SW, creating a cross-shore chop again. The energy is still strong (1517), but the quality is marginal. From Tuesday, August 18th through to Thursday, August 20th, the swell drops way off – down to 2 ft to 4 ft – with short periods and poor conditions. The energy is weak (as low as 108), so there’s really nothing to ride.
The second week picks up a bit around Friday, August 21st, with a 4 ft SSE swell and a period of 11 seconds, but the cross-shore wind returns, so it’s still not clean. The energy is 415 (moderate), but it’s a no-go. Saturday, August 22nd looks a touch better with a 5 ft SSE swell and 11 seconds, but the wind is still a fresh cross-shore, keeping it messy. The energy is 1217, which is strong, but the wind kills it.
The last real standout is Sunday, August 23rd, where we see another 10 ft ENE swell, but with a short 8-second period. The wind is a fresh cross-shore, so it’s lumpy and messy again. The wave comment says it’s too big for the break, so it’s not a great call. The rest of the period fades out with small, poor-quality surf.
So, bottom line: the best waves are on Sunday, August 16th, with a powerful 10 ft groundswell and clean cross-offshore wind. That’s the one for the experts. For the rest of us, it’s a frustrating stretch of onshore chop and messy conditions. Keep your eye on the long-range, but for now, it’s a lot of waiting.
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.
