The Lowdown
Hey folks, Rusty here. Let’s be straight: the next two weeks are a real mixed bag at Halfpoint/Fullpoint. We’ve got a solid groundswell showing up, but the wind is gonna make it a battle until later on.
Right now, through the first week of September, it’s a write-off for decent waves. The ENE wind is howling, mostly 22 to 28 mph, and it’s cross or cross-on shore creating lumpy, messy chop. The swell sits around 7 ft to 8 ft from the ENE, but the period is a short and weak 7-8 seconds. The combined wave energy reads over 1000 (1263 on Thursday afternoon for example), showing there’s plenty of power out there, but it’s all wind-slop. Not worth paddling out. That ENE direction is actually our optimum, but the wind ruins it.
The real turnaround starts on Saturday, September 5th and into Monday, September 7th. The swell drops a little to 8 ft-8 ft, but the period jumps to 13-14 seconds. That’s proper groundswell energy, and the combined energy spikes to over 2000 (2765 on Saturday morning). The problem? The wind is still cross-shore, 19-22 mph from the NE. It’s not clean, but the wave quality edges up just enough to call it *marginal*. If you’re desperate, Saturday and Sunday are the first chance for a ride, but don’t expect glassy faces.
Monday, September 7th brings a change. The wind drops to a light breeze of around 6 mph and swings onshore from the SSE. The swell is 7 ft from the ENE with a 12-second period and combined energy of 1812. The wave comment flips to “marginal surf forecast,” but the score tells me conditions are improving. The chunk of the first week is a bust for clean waves.
Then we hit a gap. Tuesday and Wednesday, September 8th-9th, see the swell drop to 4 ft-6 ft, period falls back to 8-14 seconds, and the cross-onshore wind returns. The energy reads under 1000 again. Not worth it.
The standout window arrives on Sunday, September 13th and especially Monday, September 14th. On Sunday, we get 7 ft of ENE swell with an 11-second period, but the wind drops to a gentle 9 mph cross-shore. The combined energy is 1856, which is solid. Then on Monday afternoon, we hit the jackpot for experienced surfers: 8 ft ENE swell at an 11-second period with glassy conditions—3 mph from the SE, barely a breath. The wave comment says “excellent surf conditions for experienced surfers.” The combined energy is 1499. This is the pick of the forecast. The crowd report says it’s *often* busy at this break, so expect company if you score it.
Tuesday, September 15th, and Wednesday, September 16th, fade out. The swell drops to 3 ft-4 ft, period goes all over the place, and the energy plummets (307 on Tuesday morning, then 67 on Wednesday morning for the first Wednesday!). The wind stays light but cross-shore, and the surf is poor.
The best on offer is definitely Halfpoint/Fullpoint on Monday, September 14th, afternoon. That glassy, clean 8 ft ENE groundswell with an 11-second period and light wind will be the cleanest and most powerful session in the whole two weeks. The second best is the weekend of September 5th-7th if you can handle lumpy conditions and want some size.
The water temperature here is 81°, which is pretty much bang on average for the time of year—no anomaly to speak of.
Alright, that’s the call. Keep an eye on that Monday—could be a real treat after a long wait.

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.
