The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Halfpoint/Fullpoint, and I gotta be straight with you – it’s a tough run ahead. We’re looking at a solid two weeks where the ocean’s just not playing nice. There’s no real kick-off to this forecast; the first bunch of days are a write-off, and honestly, the whole 16-day window is a struggle to find a clean wave.
The pattern is dominated by persistent cross-shore and cross-onshore winds, mostly from the ENE, blowing at 12 to 28 mph. That’s a constant battle. The swell hangs around, but the quality is wrecked by the breeze. From Monday the 14th right through to Saturday the 27th of September, every single report says “poor surf conditions.” We’re talking about a solid 13-day stretch of nothing worth paddling out for. The combined swell energy fluctuates a bit – it starts weak at around 124, builds into moderate territory (around 298 to 968), and even gets strong towards the 18th and 19th with values hitting 1124 and 1015. But it doesn’t matter one bit when the wind’s smashing it up. The waves are lumpy, messy, and just plain ugly.
You get a little flicker of hope right at the very end. On Monday the 28th of September, the wind finally backs off a touch. The morning’s still a bit ordinary with a 7 ft swell from the ENE and a gentle cross-onshore breeze, but the afternoon looks like the only real window we’ve got. The wind drops to nearly nothing – just 3 mph from the NE, practically glassy with light cross-shore ripples. The swell sits at 7 ft from the ENE, with a short period of 7 seconds. It’s a marginal call, but that light wind is the big plus. The combined swell energy is still moderate at 689. This isn’t a classic, but after two weeks of junk, it might be the only time the ocean’s not fighting you.
The water temp at the start of the period is 81°F with a tiny anomaly of +0.4°F, so it’s bang on average for this time of year – nothing weird there.
For a standout, there just isn’t one in this window. The only day worth mentioning is that Monday the 28th afternoon. The swell direction is from the ENE, and the optimum for Halfpoint/Fullpoint is ESE, so it’s not a perfect match, but the near-calm wind is your best chance for something clean. Keep in mind, with 7 ft swell, it’s getting a bit meaty for beginners.
If you’re a kite surfer, the whole first two weeks with those strong cross-shore winds and solid swell would look a lot more interesting than paddle surfing. For the rest of us, it’s a waiting game. Forecasts can change, and this stretch of poor surf is pretty normal for the area when the trade winds lock in, so don’t lose hope.
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.
