The Lowdown
Alright, Rusty here. Let’s get straight into it.
Well, I gotta be honest with ya – this stretch at Halfpoint/Fullpoint is lookin’ pretty grim for the next two weeks. We’ve got a real run of messy, windy, cross-shore and cross-onshore junk that’s just not gonna deliver any kind of quality ride. The water temp is sittin’ around 80°, which is about average for this time of year, so at least you won’t be shiverin’ while you’re gettin’ skunked.
The first few days are a write-off. Thursday afternoon the 30th of July has a weak 2-foot SSW swell with a very long 18-second period – that groundswell energy is there (559), but it’s wasted with a 15 mph cross-on breeze. Choppy, poor, don’t bother. Friday the 31st through to the weekend (1st and 2nd of August) actually sees some size buildin’ – up to 10 feet on Saturday morning – but it’s all short-period, 8-second windswell from the east, and the wind is howlin’ at 28 mph cross-shore. That’s a mess. That much energy (1578) with that wind is honestly more of a kitesurfin’ setup than a paddle surf situation. Too big and blown out for beginners, and even for experts, the quality is just not there.
The following week doesn’t get much better. The swell drops off but the wind stays stubbornly cross or cross-on from the ENE or NE, always in the moderate to fresh breeze range. The only flicker of hope comes on Tuesday morning the 4th of August. We’ve got a 5-foot swell from the ENE with a longer 12-second period, and the wind is a lighter 12 mph cross-shore. The energy is moderate (706). It’s still only a “marginal” call – the tide or somethin’ might be off – but it’s the least terrible option in the whole window. Still, don’t expect much.
After that, it’s a slow fade into tiny, weak, and messy surf. The second week sees wave heights droppin’ below 3 feet, with periods all over the shop, and the energy drops right down to 94 by Friday the 14th of August. Just a long, flat, blown-out run.
Bottom line: I can’t point to a single standout in this whole 16-day window. There’s a gap of good surf that never really starts. If you’re desperate, maybe paddle out Tuesday morning the 4th for a few grovelly ones, but keep your expectations in the dirt. This is one of those stretches where it’s better to wait for the next weather pattern to shift.
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.
