The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks.

We’ve got a long stretch ahead, and honestly, it’s a bit of a tough one. The first week and a half is pretty much a write-off, but we do see a flicker of hope further out. The main break on the radar is Halfpoint/Fullpoint. It’s a fairly consistent spot, exposed to the swell, and it prefers the swell from the ESE. The water temp is sitting about average for this time of year, which is fine.

The first real chance to get wet doesn’t come until Wednesday, September 9th. Even then, it’s only marginal. We’re looking at a small 3ft swell from the SSW, with a long 14-second period. That long period is a good sign for a point break like this, should give it some shape, but the energy is pretty weak (521). The wind is a light cross-onshore, so it’ll be bumpy. It’s a 2 out of 10 at best, just a knee-high grovel.

After that, it’s back to the doldrums. From Thursday the 10th right through to Tuesday the 16th, it’s a straight-up desert. The wind is onshore or cross-shore, the swell is small and weak, and every session is a zero. Nothing to see here.

We finally get a little pulse of longer period swell again on Thursday, September 17th. The morning shows a 3ft swell from the SSW with a very long 16-second period. That kind of period is proper groundswell, and it’ll wrap into Halfpoint/Fullpoint nicely. The combined energy is moderate (608). The wind is a moderate cross-shore, which is workable but not ideal. It’s still a marginal forecast, scoring a 1. This is a long-range call, so keep an eye on it, but it’s looking like the most promising window so far.

Friday the 18th sees the swell size jump to 6ft from the ENE, but the period drops to a short 7 seconds. That’s windswell, and combined with a cross-onshore wind, it’s going to be a choppy, lumpy mess. The energy is moderate (453), but the quality is poor. This one is better left for the kiters.

The final standout is the weekend of September 19th and 20th. On Saturday morning, we get another 3ft, 16-second SSW groundswell, with a light cross-onshore breeze. The energy is moderate (696) and the score is a 1. Saturday afternoon steps it up to a 4ft swell with the same long period, and the wind drops to a light breeze. The score climbs to a 2. That’s the best of the entire run – clean-ish conditions at a point break with real south groundswell. Sunday the 20th is similar but with a stronger breeze, so it’s not as clean.

The Verdict: If you’re desperate for a paddle, the very best bet is Saturday afternoon, September 19th at Halfpoint/Fullpoint. It’s a small but long-period SSW groundswell with light wind. It’s not going to be epic, but it’s the only session in the whole 16 days that looks even remotely fun. The rest of the time, you’re better off taking the dog for a walk. Mondays and Tuesdays of the second week might offer a bump, but nothing to get excited about.

Stay patient, and don’t bother checking the forecast every day until mid-September.

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.
