The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next 16 days at Halfpoint/Fullpoint are a real mixed bag, and honestly, for a lot of it, you’re better off staying home. The first week is a write-off with poor surf conditions, but we do see a glimmer of hope in the second week. The standout window is the morning of Wednesday, 29th July, which is the best bet on offer.
The water temp is sitting around 80°, which is pretty much normal for this time of year – nothing to get excited about.
We kick off Monday, 20th July with nothing rideable. The swell is small and messy, with a cross-shore wind kicking up a chop. This pattern of poor conditions drags on through the whole week. Even though there’s some decent swell energy building – the combined energy hits 985 (moderate) on Thursday, 23rd July – the winds are too strong and cross-shore, ruining any chance of clean surf. The swell direction is mostly from the SSW, which isn’t ideal for this spot anyway.
The weekend of 25th-26th July sees the combined energy climb into the strong range (1695 and 2158), and the swell period gets long, up to 18 seconds. That’s a proper groundswell, and it’s coming from the E and ESE, which is a better angle. But the problem is the wind. It’s a fresh cross-shore, so the surface is lumpy and choppy. It’s only rated as marginal, so it’s a gamble.
The real standout comes on Wednesday morning, 29th July. The wind drops to a gentle breeze from the NE, still cross-shore, but the lightest we’ve seen. The swell is 6ft from the ENE, with a period of 11 seconds and combined energy of 1045 (strong). The wind is only a slight cross-chop, so the waves will have some shape. It’s still a bit lumpy, but it’s the cleanest the whole forecast gets. The swell is over 5ft, so it’s a bit much for beginners, but for intermediates, this is the session to aim for. The morning is the pick.
After that, it fades. The energy drops off, and the wind picks up again, with strong breezes returning by the end of the month. The first week of August looks like a repeat of the first week – poor surf and messy conditions.
So, to wrap it up: the first week is a gap with no real surf. The second week has some promise, but Wednesday morning, 29th July is the only clear standout. Get out there early if you can.
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.
