The Lowdown
Alright folks, Rusty here. Gotta be straight with ya – we’re looking at a pretty grim stretch ahead. This forecast is basically one long, frustrating wait for the ocean to sort itself out.
We’ve got a near-constant barrage of strong cross-shore winds, mainly blasting out of the ENE at 18 to 28 mph. That means lumpy, cross-chop conditions are the name of the game for days. It’s not surfable; it’s a washing machine. The swell energy is all over the place, but a lot of it is weak-to-moderate until a massive, ugly spike shows up. That spike is on the morning of the 8th of September, with a huge 16ft swell from the SSW and a combined energy reading of 10220 – that’s a big ocean out there. But don’t get your hopes up. The wind is a strong cross-onshore, making it a total mess. It’s a beast, but it’s only really a kite-surfing wind if anything. That kind of power with that wind direction is just not for the paddle crew.
Honestly, for the first twelve days, from the 2nd of September all the way through to the 13th of September, there isn’t a single window I’d recommend paddling out. It’s a long, dry gap. Most of the time the wave comment is just “poor surf conditions.” Even the “marginal” calls are let down by the wind. And that water temperature is about 81°, so it’s your typical warm bath for the time of year – nothing weird going on there.
Things calm down eventually, but nothing screams quality.
Halfpoint/Fullpoint
This spot is exposed to the swell and needs an ESE wind to be at its best, but it’s constantly getting hammered by a strong cross or cross-onshore breeze from the ENE or NE. For a break that’s fairly consistent and usually an intermediate-level wave, it’s just getting smoked. The only day that even sort of hints at something is the morning of the 9th of September. The swell drops to 3ft from the SSW with a long 14-second period, and the wind finally eases up to a light 6 mph cross-onshore. The combined energy is a pretty weak 630 though, so while conditions might be the least terrible out of the whole run, the wave itself will be pretty weak and slow. It’s still not good, but it’s the only day that’s not a total write-off.
Sorry, folks. This look is a blank one for the area. It’s a long run of days with nothing on offer. Forecasts can always change, but for now, we wait.
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.
