The Lowdown
Right then, let’s have a look at what’s on offer for Halfpoint/Fullpoint over the next couple of weeks. I won’t lie to you, it’s a pretty grim stretch of days ahead. The wind is our enemy here, and it’s gonna be howling from the ENE or NE for almost the entire period, which is cross-shore or cross-onshore at this spot. That’s going to leave things lumpy, choppy, and messy, with no real chance of a clean wave. These conditions are labelled as poor surf throughout the whole forecast, so honestly, there’s nothing to get excited about.
From the very start on Thursday the 13th of August, we’ve got a 22 mph cross-wind messing up a 3 ft S swell. The wave energy is moderate (847 to 969), but it doesn’t matter because the wind is just ruining it. The water temp is about average for the time of year, so no surprises there.
Friday the 14th sees the swell bump up to 7 ft from the ENE, but the period is a short 8 seconds, and the wind is still strong cross-shore at 25 mph. The energy picks up into the strong range (1059), but it’s still a write-off. Things actually get worse into Saturday the 15th with near gale force winds at 31 mph whipping up a 12 ft E swell. That’s for experts only if it was clean, but it’s not – the combined wave energy is very strong (2281) but the surf is completely blown out.
There’s a bit of a drop in swell size around Tuesday the 18th, with 4 ft to 5 ft ENE windswell, but the wind stays fresh and cross-onshore. The energy drops to moderate (323), but the quality is still poor. Even when the swell goes teeny tiny, like 1 ft to 2 ft from the SSW around the 19th and 20th, with a long period groundswell (16-18 seconds), the wind is still cross and moderate to fresh, making it unsurfable. The longer period would normally make for better shaped waves, but the direction (SSW) might not match the optimum ESE for this spot, and the wind kills the chance anyway.
We get a run of very weak energy (in the 100s) around the 21st and 22nd of August, with 3 ft or less of NE/ENE swell. The wind eases slightly to moderate, but it’s still cross or cross-onshore, so still poor. By Sunday the 23rd, the swell jumps back up to 5 ft from the E with a short 7-second period, and the wind is back up to 22 mph cross-shore – messy again. The final few days through to the 28th of August are more of the same: poor surf, onshore or cross wind, and all with fresh breezes.
To be blunt, I have to call it for what it is. There is not a single standout session in this entire 16-day window. The wind just doesn’t let up, and the swell direction (almost always ENE or S) is not optimum for Halfpoint/Fullpoint, which prefers an ESE direction. The consistent ENE wind keeps the sea in a constant state of wind-chop. Even when the swell has a long period and bigger size, the wind destroys the surface. This stretch is looking like a complete blank for the surfer – nothing worth paddling out for.

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.
