The Lowdown
Alright folks, Rusty here. Let's be straight with you about what's happening at Halfpoint/Fullpoint. The whole 16-day window is a tough one. The wind is stuck in a cross or cross-onshore groove from the ENE or NE, which is just not lining up with what we need here. The swell direction is all over the shop, but mostly coming from the wrong side of the compass for this place. The water temp is sitting at 80.2°, which is about bang on average for this time of year.
We kick off on Thursday the 10th of September, but it's a write-off. A 5ft ENE swell with a short 7-second period and a 15.5 mph cross-on breeze means poor, choppy conditions. That combined energy reading is at 686 (moderate) but it's useless with that wind. That theme runs right through the first week and into the second – every session is marked as "poor surf conditions" with moderate to fresh cross-shore winds. Thursday the 17th sees the biggest swell of the run, a 6.6ft ENE pulse, but with a screaming 25 mph cross wind, it's just a messy, blown-out wall. The wave energy hits 1029 (strong), but it's unrideable for a paddle surfer; honestly, that setup looks more interesting for kite surfing than paddle surfing.
The only flicker of hope comes right at the end. The afternoon of Tuesday the 22nd of September and the morning of Wednesday the 23rd finally nudge into "marginal surf" territory. We're looking at a 5.6ft to 5.2ft E/ENE swell with a period of 10 seconds. The wind is still cross or cross-on, but it's backed off to a moderate breeze of 12-15.5 mph, and the wave energy is strong (661 to 870). It’s not going to be clean, but if you are desperate and you know this break, the Wednesday afternoon session on the 23rd might offer the most power. A 5.2ft swell at 10 seconds from the E is the best we get, but don't expect anything clean. It's a rough outlook, lads.

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.
