The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for the next couple of weeks.
Right off the bat, I gotta be honest with you – it's a rough stretch. We're looking at a solid run of messy, blown-out conditions at Halfpoint/Fullpoint that just won't let up. The wind is a constant cross-shore or cross-onshore, hanging around 15 to 25 mph for days on end, which is just gonna wreck any chance of a clean face. The water temp is about what you'd expect for this time of year, nothing out of the ordinary.
We kick off on Friday, August 7th, with a tiny 1 ft SSW swell but it's so weak the combined energy is only 148 – not worth paddling out for. That sets the tone. Saturday the 8th sees a bump in size to 6 ft from the ENE, but it's a short-period windswell, period around 7 seconds. The energy picks up to 398, but with that fresh cross-shore wind and lumpy chop, it's a total write-off.
This pattern just keeps grinding through the week. Sunday the 9th has 5 ft to 6 ft ENE swell, energy climbing to 609, but it's still messy. Monday, Tuesday, same story – cross-shore winds, lumpy conditions. The swell direction shifts around a bit, with a bit of S swell coming in on Wednesday the 12th, even a long-period 18-second groundswell, with energy jumping to 892. But the wind stays on it, so the quality is just not there.
As we get into the second week, the wind actually gets stronger. Thursday the 13th through Sunday the 16th, we're seeing strong breeze around 25 mph, with the swell hitting 8 ft and even 10 ft. The combined energy is massive on the 16th – 1324 – that's some serious power. But with that much wind, it's going to be a washing machine. For most surfers, this is going to be a slog. That 10 ft stuff is expert-only territory anyway, and with the wind, it's gonna be a battle.
The last glimmer of hope is right at the end. Thursday, August 20th, the wind finally drops to a moderate breeze, 12 mph, and the wave comment changes from "poor" to "marginal" for the first time. The swell is 5 ft from the ENE, energy at 516. It's still cross-shore, so it's not perfect, but it's the best we've seen in two weeks. Friday the 21st morning might be the pick, with a gentle breeze of 9 mph, but it's a short window.
Honestly, if you're set on getting wet, that Thursday and Friday the 20th and 21st are your only real shot at something rideable, but it's going to be a gamble. The rest of the run is a hard pass. If you've got a kite, this whole stretch looks a lot more interesting than paddle surfing.
Stay patient, and keep an eye on the forecasts. Things can change.
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.
