Alright, folks, Rusty here. Let’s have a proper look at what’s coming down the line for Halfpoint/Fullpoint. Gotta be straight with you – it’s a tough stretch ahead. The whole 16-day window is looking pretty grim, with next to nothing worth paddling out for. The water’s sitting at a warm 79°, which is about average for this time of year, so no surprises there.
The problem is the wind. It’s stuck blowing from the ENE, which is a cross-shore or cross-onshore direction for this spot, and it’s strong. We’re looking at 18 to 25 mph winds for days on end, just tearing the surface up. The swell is coming from the wrong direction too – mostly ENE – and the periods are short, usually 7 to 8 seconds, meaning weak, choppy, wind-affected junk. The combined energy is moderate (418 to 697) but it’s all messy.
That first recommendation doesn’t actually come until the very end of the period. We’ve got a solid 15-day gap of zero-rated surf. From Sunday, July 12th, right through to Saturday, July 26th, every single session is rated a 0 out of 10 – “poor surf conditions.” It’s a long, bleak run.
The only glimmer, and I mean a tiny glimmer, shows up on Monday, July 27th. The morning surf is marginal, with a 1 out of 10 score. The swell is 3 ft from the ESE, with a decent 15-second period – that’s groundswell energy showing up. The combined energy is strong (835). The wind is a gentle 9 mph from the ENE, so it’s still a cross-shore, but the surface is only slightly choppy. It’s not clean, but it’s the least ugly day of the lot.
The standout, if you can call it that, is Monday afternoon on July 27th. The score nudges up to a 2 out of 10. The swell is still 3 ft from the ESE, with a 14-second period, and the combined energy is still strong (789). Critically, the wind swings to a light 12 mph cross-offshore from the NNE. The report says “clean.” For this forecast, that’s a miracle. It’s the only session in the whole 16 days where the wind is truly offshore and the surface is clean. The swell is small, but with that long period, it’ll have some push. The optimum swell direction for Halfpoint/Fullpoint is ESE, and that’s exactly what we’ve got. So, for a brief window on that Monday afternoon, it might just be worth a look if you’re desperate. Don’t expect any kind of classic session, but it will be the best possible option in a very poor run.
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.
