The Lowdown
G’day, I’m Rusty. Let’s have a proper look at what’s on offer at Halfpoint/Fullpoint over the next 16 days. Right off the bat, I’ve got to be straight with you – it’s a pretty grim stretch. We’re looking at a long dry spell with no real surf to get excited about for the first week and a half. The water’s sitting at 80°, which is pretty much bang on average for this time of year, so nothing weird going on there.
Thursday morning, 20 August, kicks things off with a tiny 2ft SSW swell, and a period of 18 seconds – that’s a real long-period groundswell. Combined energy is weak at 303, but the wind is a cross-shore from the ENE at 9 mph, so it’s a little lumpy. The forecast calls it marginal, and honestly, it’s not worth paddling out for. Thursday afternoon gets even worse with a 0 rating. Friday the 21st sees a switch to a 2ft ENE swell, but the period drops to a pathetic 7 seconds, and the combined energy plummets to 81. Wind is light cross-onshore in the morning, so you’ve got small wind ripples – just messy. That poor quality continues all through the weekend and into the next week. Saturday the 22nd has 4ft of short-period ENE swell, but the wind is a fresh 22 mph cross-shore, and it’s lumpy. Sunday the 23rd bumps up to 6ft, but with 28 mph winds, it’s a complete mess. Nothing is rideable.
Monday the 24th stays ugly, and by Tuesday the 25th the combined swell energy jumps to 576, but the swell is still short-period at 8 seconds and the wind is fresh and cross-onshore – it’s lumpy, not surfable. Wednesday the 26th through to the end of August stays poor, with scores of zero across the board. Even when the swell height gets up to 7ft on Sunday afternoon, 30 August, with a combined energy of 1704, the wind is still a fresh cross-shore, and the swell period is short. It’s just not coming together.
Finally, on the 1st of September, Tuesday morning, we see 8ft of ENE swell at 12 seconds, with a combined energy of 1715. The wind remains cross-shore at 19 mph, so it’s still lumpy. The forecast calls it marginal again. Wednesday the 2nd of September is the only real standout in the whole 16 days. Wednesday afternoon sees 6ft of NE swell, period 9 seconds, combined energy 696, and the wind switches to a cross-offshore at 16 mph, which is described as “clean.” That’s your best chance. The swell is a bit big for beginners at over 5ft, but it’s manageable. The offshore wind will clean it up nicely at Halfpoint/Fullpoint, which is exposed to an optimum ESE direction – the NE swell won’t be perfect, but clean conditions can make up for a lot. Thursday the 3rd drops back to weak surf and poor conditions. Friday the 4th has 5ft of ENE swell, but the period is short at 7 seconds, and the wind is light cross-onshore – another marginal call.
So, where’s the good news? There isn’t much. The one day worth marking on your calendar is Wednesday afternoon, 2 September. Clean, offshore wind, decent size at 6ft, and the energy is moderate at 696. Everything else is either too small, too windy, or too messy. Crowds are often at Halfpoint/Fullpoint, so on that Wednesday expect company, but it’s the only game in town. The rest of the run is a write-off, I’m afraid.

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.
