The Lowdown
Alright, let's be real. Looking at the whole 16-day picture for Halfpoint/Fullpoint, it's a tough stretch. The first week and a half is basically a write-off with a persistent cross-wind messing up what little swell there is. We've got a decent pulse of energy coming in the second week, but it's still fighting that wind.
It kicks off Saturday the 12th with tiny 2ft of ENE swell and a cross-shore breeze. It's messy and not worth paddling out for. This same story basically holds through to the end of the week: small waves, cross-shore winds, and "poor surf conditions" being flagged. The water is a warm 81°F, which is about average for the time of year, but the quality is just not there.
We do see a jump in the combined swell energy mid-week – hitting some moderate to strong numbers (686 on Wednesday the 16th, 604 and then a massive 1108 on Thursday the 17th). But that's misleading. That Thursday sees a 7ft swell from the ENE, but with a 25 mph cross-shore wind, the ocean is going to be a churning, choppy mess. At that size and with that wind, this is looking more like a kitesurfing setup than anything else. It's just too big and blown out.
The real window to look at is the tail end. Friday the 25th of September is the only time things might line up. The swell drops to a clean 3ft from the SSW with a long period of 14 seconds, and the wind swings light from the ESE. It's still cross-onshore, but very light (3 mph). The wave comment is "marginal," but with a score that's the highest in the entire run, it's the best we've got. The combined energy is still moderate (524), but that long-period groundswell could wrap in and offer some clean, fun shapes if the wind holds.
That's it. One day, two weeks out, that's the standout. It's a long-range promise, so don't book the trip yet, but keep an eye on it.

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.
