The Lowdown
Alright, Rusty here. Let’s chew over what’s on the table for Halfpoint/Fullpoint.
Look, I’m not gonna sugar-coat it. The forecast for Halfpoint/Fullpoint is a long, drawn-out battle with onshore and cross-shore wind. For the next week and a half, the wind is blowing from the east and northeast, 15 to 25 mph. That means most of the time we are dealing with lumpy, choppy, and messy conditions. The swell is generally small, around 2 ft to 4 ft and short period, or when there is a longer period swell, it’s from the south which doesn’t match the optimum direction from the southeast.
The water temp is sitting at 81°, which is about average for this time of year, so at least it will be warm while you get thrashed by the wind.
Now, here is the one standout worth circling on your calendar. Saturday, 15th of August afternoon is where things get interesting. The wind is from the north at 25 mph, but it’s cross-offshore, so the surface will be clean. The swell is predicted to be too big for this break at 10 ft from the east-northeast with a 12-second period. That is some real groundswell energy and the combined energy is pumping at a massive 2797 (strong wave energy). For a spot exposed to the east-southeast, this is a powerful swell. However, it is well overhead, and likely only for the experienced crew. The reports say it might be too big for the break itself, but if you have the skills and respect the power, it will be the cleanest, most powerful wave of the 16-day run.
The closest other possibility is the Saturday morning before it, the 15th. Still big at 8 ft from the ENE but with a 10-second period, and the wind is cross-offshore from the north-northeast at 25 mph, so it will be clean. The combined energy is strong at 1644. It is right on that edge for experts only.
But before that, from now right through Friday the 14th, it is a write-off. The wind is cross or cross-on from the ENE to NE, with speeds of 15-25 mph creating lumpy chop. The swell height is modest, and the combined energy is moderate to strong but the quality is ruined by wind. It’s not paddle surfing; if you had a kite, you might have some fun in the breeze.
After the 15th of August, the wind swings back onshore from the SSE and east, putting a stop to any quality. The rest of the week and the following week is just more of the same messy, cross-shore wind with middling swell that doesn't really offer any clean, well-shaped waves. There is a very long-period swell (23 seconds) on Monday the 24th of August afternoon, but with a 22 mph cross-shore wind, it will be a bumpy, straight mess at a point break.
So, if you can handle the big stuff, the afternoon of Saturday the 15th of August is your shot. Get there early, the tide will be doing its thing. Otherwise, this outlook is a long grind.
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.
