The Lowdown
Alright, let’s get into it. It’s Rusty here.
Look, to be straight with you, the next week and a bit is a write-off. We’ve got a solid 16-day window ahead, but honestly, for the first ten days, from Thursday the 27th of August right through until Saturday the 5th of September, it’s pretty grim. The wind is howling out of the ENE, 19 to 25 mph, and it’s cross-shore all the way. That means lumpy, choppy, messy conditions. Even when there’s a bit of swell, the quality is shot. The only break on the radar is Halfpoint/Fullpoint, but with that wind, it’s not worth paddling out.
The water temp is sitting at 81°, which is bang on average for this time of year, so no surprises there.
Now, we finally get a glimmer of hope. On Sunday the 6th of September, the energy jumps. We’re seeing moderate cross-shore winds, but the combined swell energy hits 2121 (strong) in the morning, dropping to 1461 in the afternoon. The swell hangs around 6ft to 7ft from the ENE with a period of 10 seconds. It’s still not perfect—the wind is cross-shore—but it’s the first sign of life. The afternoon session on Sunday the 6th gets a score of 2 out of 10, which is the best we’ve seen so far.
Then, Monday the 7th of September morning is the real standout. The wind drops right back to a light breeze from the NE at 6 mph, and we get a 3ft groundswell from the SSW with a very long period of 15 seconds. That is clean, lined-up, and will wrap around the point beautifully. The combined energy is 1036 (moderate), and the morning score is a 3. The water is still clean, light cross-shore ripples only. This is the best session on offer. The long period means longer waits between sets, but the shape will be quality, and paddling out will be easier. Crowds could be an issue—it says they’re often there—so get in early.
The afternoon on the 7th and the rest of the 8th and 9th of September fades again as the wind picks up and the quality drops back to poor.
Then hold on for Thursday the 10th of September afternoon. The wind turns NNW at 6 mph, cross-offshore, and the conditions go clean. We’ve got a 3ft swell from the E with an 11-second period and moderate energy (572). The score for that session is a 3—expect very good surf. It’s small but clean and will be fun on the point.
Friday the 11th of September morning has a chance too: a 5ft swell from the E, 11-second period, with a light onshore from the SE. That brings a score of 2. It’s marginal but worth a look if you’re keen.
So the standout is Monday the 7th of September morning. Clean, long-period groundswell, light winds. That’s the one to circle. The afternoon of Thursday the 10th is the backup—smaller but glassy.
This has been a long dry spell, but it does tend not to stay flat here for long. Forecasts can change. Keep an eye on it.
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.
Halfpoint/Fullpoint is 15 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
