The Lowdown
G’day, Rusty here. Let’s have a good hard look at Halfpoint/Fullpoint. I’m not gonna lie to you, the next couple of weeks are a bit of a mixed bag. We’ve got a decent run of swell coming through, but the wind is going to be our biggest headache. That easterly-northeasterly breeze is gonna be blowing cross-shore almost the whole time, which means lumpy, choppy conditions for most days.
We kick off on Sunday the 19th of July with some ENE swell around 5 ft, but that ENE wind at 22 mph is cross and fresh. The water is sitting at 80° which is pretty normal for this time of year, no real anomaly there. The wave energy's moderate (425), but the poor surf conditions mean it’s just not worth paddling out.
This cross-shore wind pattern sticks with us right through to Thursday the 23rd. We get a bit of a shift on the Monday afternoon with a 3 ft S swell at 16 seconds, which is a proper long-period groundswell. The energy bumps up (535), but that ENE breeze is still ruining it. Tuesday the 21st also has some S swell, 3 ft at 14 seconds, again let down by the wind.
Wednesday the 22nd afternoon sees the swell jump to 5 ft from the ENE, period of 11 seconds, and the energy gets strong (1144). But again, fresh cross-shore wind just chops it up.
Thursday the 23rd brings a 2 ft SSW swell with a very long period of 20 seconds. The energy is strong (944), and the wind is a strong cross-shore. This is a perfect example of a long-period groundswell that’s going to break too straight at a beach break. It would be better suited to a point or reef, but here at Halfpoint/Fullpoint it’s just messy.
Friday the 24th sees the swell building to 7 ft and 7 ft from the ENE, period around 7 seconds (short period, weak energy). Then Saturday the 25th keeps the ENE swell at 7 ft in the morning, period of 8 seconds, with moderate to strong energy (1147). The afternoon swings to a 3 ft SSW swell at 18 seconds, with a massive energy reading of 1195. The wind, you guessed it, cross-shore and fresh. The outlook remains marginal, and that’s the best we can say.
Sunday the 26th is interesting. We’ve got an E swell at 4 ft to 4 ft, period of 16 seconds. That’s a long-period groundswell. Energy is very strong (1513-1613). The wind is a moderate to fresh cross-shore, so still not clean. But given the energy and the long period, if the wind ever backs off, this one could be special.
From Tuesday the 28th onward, we see a consistent run of ENE swell between 5 ft and 7 ft, with periods between 10 and 14 seconds. Energy stays strong (1081-1523). The problem remains the cross-shore wind. It’s not until Sunday the 2nd of August that we finally see a change. On that Sunday morning, we have a gentle breeze (9 mph) from the east, cross-onshore, with a 4 ft SSW swell at 16 seconds. The energy is very strong (1464), and the wind is lighter than it has been. The score is a 2, which is the highest we see in the whole period. That’s probably your best bet, but it’s still not going to be glassy.
If I had to pick a standout, it would be the Sunday morning of the 2nd of August. The lighter wind and the long-period SSW groundswell offer the best chance of something rideable. But don’t get too excited. The rest of the period is more of a “watch and wait” situation. For a break that’s fairly consistent, it’s a tough stretch.
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.
