The Lowdown
Alright folks, Rusty here. I’ve had a hard look at the charts for Halfpoint/Fullpoint, and I gotta be straight with you – it’s a grim stretch ahead. Don’t get your hopes up too early.
Right off the bat, we’re looking at a solid 8ft swell from the ENE on Thursday the 3rd, but with a 25 mph cross-breeze screaming across it, that’s a hard pass. The water temp is sitting at 81°, which is dead average for this time of year, but you won’t be enjoying it. The wind is just shredding any chance of a clean wave.
Friday the 4th through the weekend is more of the same story. The swell hangs around, hitting 7ft on Saturday with a 13-second period from the ENE, but that persistent cross-shore wind – 19 to 22 mph – is just making a mess of things. The combined energy is pumping (over 2300 on Saturday), but it’s all wind-chop and lumpy lines. Not worth paddling out for.
Monday the 7th afternoon gets a bit wild with a 13ft SSW swell and a 15-second period, but the wind swings strong onshore from the SE at 22 mph. That’s a washing machine, and honestly, it looks more interesting for the kite boarders than for us paddle surfers. Way too big and blown out for anyone but the most hardcore.
Following that, the swell drops right off. Tuesday the 8th sees a 5ft ENE swell, but the wind stays on it. From Wednesday the 9th through to the end of the run, we’re looking at mostly small, weak swells (3ft or less) with fresh to strong cross-shore winds. The combined energy drops into the low hundreds, sometimes just 364 or 231. Periods drop to 8 seconds, so it’s all short-period, weak wind swell. There’s not a single decent window to recommend.
The whole 16-day outlook is basically a washout for Halfpoint/Fullpoint. The wind is the villain here, and it just won’t let up. We’ve got a good week of blown-out, messy surf before things get small and weak. When it’s this persistent, you just have to wait for the next forecast change.
Rusty, signing off.

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.

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.
