The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s doing over the next few weeks at Halfpoint/Fullpoint.
Mate, I’ll be straight with you—this stretch is looking pretty grim for a solid run. The first week is a real struggle. Wind is hammering in from the ENE almost every day, sitting around 18 to 25 mph, and it’s cross-shore or cross-onshore the whole time. That’s throwing up lumpy, messy cross-chop that’s just not worth paddling out into. The swell is mostly short-period windswell between 6 and 8 seconds, with heights struggling to get above 4 ft to 6 ft, but the wind wrecks any chance of a decent wave face. The combined wave energy is moderate to strong (up to 512 in the first few days) but it’s all junk. Water temperature is sitting at 80°F, which is pretty normal for this time of year, so no surprises there.
There’s a bit of a lull mid-week around the 22nd and 23rd of July, where the swell drops right off to under 2 ft, even though there’s a long-period groundswell from the SSW (20 to 24 seconds). The energy is strong (over 700), but with a tiny wave height and that persistent ENE wind, it’s still not a goer. The period is very long, which would usually be better on a point or reef, but with the wind and size, it’s a pass.
Now, the second week starts to show some promise, but it’s still not clean. From the 28th of July (Tuesday) into the 30th, we see a bigger swell push in from the ENE and E, with heights hitting 6 ft to 8 ft. The period lengthens to 12 to 14 seconds, which is a better groundswell, and the combined wave energy is strong to very strong (over 1000, hitting 3062 on the 28th morning). That’s serious energy. But here’s the catch—the wind is still cross-shore from the NE and ENE, 12 to 18 mph, so the surf stays lumpy with cross-chop. The 28th morning swell is 8 ft, which is expert territory, and the 30th morning has 6 ft with a moderate cross-shore, which is the best of a messy bunch. The wave comment flips to “marginal” on a few of these, so it’s not completely hopeless, but it’s not clean.
The standout, if you’re desperate, is the Thursday 30th July morning at Halfpoint/Fullpoint. Swell from the ENE at 6 ft, 12-second period, combined energy of 1080 (strong), and the wind drops to 12 mph from the NE—still cross-shore, but a moderate breeze rather than a fresh one. It’s still cross-chop, but it’s the most manageable session in the whole 16-day window. This is one for experienced surfers; 6 ft is a solid size, and the period is decent. The break is fairly consistent, but crowds are often around, so expect company.
After that, the end of the run into the 1st of August drops off quickly, with swell under 3 ft and weak energy. Honestly, this stretch looks more interesting for kite surfing than paddle surfing, given the persistent cross-wind and lumpy conditions.
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.
