The Lowdown

Hey, Rusty here. Gotta be straight with you—this forecast for Halfpoint/Fullpoint is a real struggle. We’ve got a big gap before anything worth mentioning. The first decent shot doesn’t come until Thursday, September 25th, so we’re staring down almost two weeks of pretty grim conditions. That wind out of the ENE just won’t let up, mostly cross or cross-onshore, and the surf quality is poor every single day.

Early on, the swell is tiny and hammered by the breeze. The water temp is 81°F with an anomaly of just 0.2°F, so totally normal for this time of year. For the first week and a half, you’re looking at small, chopped-up waves—most under 3ft, short period, just messy. The combined energy is in the low to mid hundreds, which is weak to moderate, but it’s all for nothing with that wind. On September 17th we get a pulse of 7ft swell from the ENE, but it’s cross-shore and lumpy with a stiff breeze—no good. That afternoon even shows 7ft swell and combined energy of 1008, but it’s still cross-shore and messy. Not for a paddle board.

Then it finally turns. Thursday, September 25th is the one to mark. Friday morning we get a 7ft swell from the east, period up to 10 seconds, and the wind goes light from the ENE—gentle breeze, just a slight cross-chop. That’s the cleanest we see, and the combined energy hits 1020, which is strong. It’s still a marginal call, but compared to everything else, this is the standout. For a spot that’s exposed to east-southeast swells and fairly consistent, this is your best chance. With 7ft swell, it’s on the bigger side for beginners, but intermediates should get some. Crowds are often here, so don’t expect a solo session.

There’s a little hope on the Thursday before, September 24th, with 6-6ft swell and light onshore wind from the SSE, but it’s still marginal. Not worth rushing for. The next Saturday, the 26th, slides back into that same old cross-shore chop.

So yeah, there’s a long quiet spell until the 25th. That Friday is your play, but keep expectations in check—it’s just the least ugly option in a rough stretch. The forecasts can change, and this spot doesn’t stay flat forever.

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.

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.
