The Lowdown

Alright, Rusty again. Let’s run through it in feet and miles per hour for the crew that thinks that way.

Halfpoint/Fullpoint is the only game in town, and brother, it’s a tough game right now. From the 29th of August all the way through to the 13th of September, we’re looking at a near-total blank. The first hint of anything you’d even call marginal comes on the afternoon of the 13th of September.

For the first two weeks, the wind is relentless. A solid ENE to NE breeze, blowing 22 mph to 28 mph, day in and day out, all cross-shore. That means nothing but cross-chop and lumpy, chopped-up waves. The water temp on the 29th of August is a warm 81°F, pretty much spot-on average for the time of year.

The swell does get big. By the 6th of September Sunday afternoon, you get a massive 13ft swell from the ENE at 11 seconds, with a combined energy of 4141—that’s serious power. But that 28 mph cross-shore wind turns it into a washing machine. That big of a wave is experts-only territory anyway, and with that wind, it’s more of a survival mission than a session.

The only ray of light, and it’s a weak one, comes on the 13th of September Sunday afternoon. The wind finally drops to a light 6 mph from the East, just enough to ruffle the surface. But the swell is tiny, only 2ft from the SSW, though with a long 15-second period. That’s a long-period groundswell, but it’s barely breaking. The combined energy is only 328, so it’s weak. You could maybe paddle a log out there and catch a few nuggets, but don’t hold your breath.

This break is usually fairly consistent, so a run this long with nothing is unusual. Forecasts change, but right now, the whole window from late August through mid-September is cooked. With all that strong wind and messy surf, this setup is far more interesting for the kite crew than the paddle crew for pretty much the whole stretch.

Hang in there.
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.
