The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s on the cards for Halfpoint/Fullpoint over the next couple of weeks.
Straight up, I’ve got to be honest with you – this is a tough stretch. The whole 16-day window is a write-off for quality surf. The swell that shows up is small, short-period, and coming from directions that don’t suit this spot – the optimum swell direction is ESE, and we’re seeing a lot of ENE and S/SW energy. On top of that, the wind is almost always a fresh cross-shore or cross-onshore breeze, keeping things lumpy, choppy, and messy. There’s nothing here that’s gonna get the heart pumping.
Right now, on Wednesday 26th August, we’ve got a tiny 2 ft SSW swell with a 14-second period, but the wind is cross at 22 mph, and the water is a warm 81°, pretty normal for this time of year. The combined wave energy is weak, sitting at 578. It’s a poor surf call – zero score. That theme just keeps rolling day after day.
Thursday 27th sees a slight bump in swell to 4 ft from the south, period 17 seconds, but same cross wind, same lumpy mess. The energy picks up a bit to 898, still moderate, but the quality is gone. Friday 28th drops back to 3 ft and 3 ft, still S swell, still cross wind.
Then from Saturday 29th through to Tuesday 1st September, the swell direction swings to ENE, but the period drops to 7-9 seconds – that’s short-period, wind-affected slop. Heights are between 5 ft and 6 ft, but with that short period and persistent cross wind, it’s just messy. Energy values are in the moderate range, between 451 and 754, but it’s all for nothing.
Wednesday 2nd and Thursday 3rd September are more of the same – 5 ft to 6 ft ENE swell, 8-second period, cross wind, poor. Friday 4th September is a little smaller, 5 ft to 5 ft, still ENE, still cross.
Saturday 5th September brings a bit of a change: a 4 ft swell from the east with a longer 11-second period, but the wind is cross-onshore, and the energy is moderate at 634. Still poor.
Sunday 6th September sees a return to SSW swell, 2 ft to 3 ft, with a 16-second period – that’s a long-period groundswell, but it’s tiny and the cross wind ruins any chance. The energy on Sunday afternoon jumps to 726, still moderate.
Monday 7th September has the strongest energy of the whole run – 1174 (moderate) from a 3 ft SSW swell with a 16-second period, but again, cross-onshore wind at 19-22 mph means it’s lumpy and poor. This is a classic case of a long-period swell that would need a point or reef to shine, but the wind and size just aren’t cooperating.
The rest of the forecast – Tuesday 8th through Thursday 10th September – is more of the same: small ENE or SSW swell, short or long period, but always with that fresh to strong cross wind. Energy values drop back to weak to moderate (360 to 637). Thursday 10th even has rain showers.
So, bottom line: there are no good surf options in the next 16 days. This spot is fairly consistent normally, so a blank run like this is a bit of a rarity. Forecasts can change, but right now, I’d be parking the board and finding something else to do. The setup here – with the consistent cross wind and moderate-sized, short-period swell – would honestly be more interesting for kite surfing than paddle surfing.
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.
