The Lowdown
Right then, let’s get stuck into this.
Truth be told, it’s a rough stretch ahead for Halfpoint/Fullpoint. We’ve got a solid 16-day window to look at, but the surf is compromised for the vast majority of it. The main issue is a persistent, strong cross-shore wind from the ENE—blowing at 19 to 28 mph for days on end—which trashes the wave face. The water temp is sitting at 81°, which is about average for the time of year, so no surprises there.
The first real sniff of activity comes Sunday the 2nd of August, but it’s a write-off straight away. We’ve got a 7 ft ENE swell at a short 8 seconds, but with 25 mph cross-shore wind, it’s just a mess of cross-chop. The combined swell energy is moderate at 865, but it doesn't matter with that wind. This pattern basically holds for the whole first week. The swell ebbs and flows, but the wind stays cross or cross-on, never giving us a clean face. There’s a slight change on Tuesday the 4th—a 5 ft ENE swell with a longer period of 11 seconds and a lighter 9 mph cross-shore wind—it’s the closest we get to a surf window, but it still only scores as marginal due to poor tide conditions and that cross element.
After that, the 7th of August sees a tiny 1 ft SSW groundswell with a very long 14-second period come through, but the wind is still smashing it at 19 mph. The combined energy is weak (156). That long period and small size is more of a novelty for a point break, and with the wind, it’s not worth paddling for.
The second week gets worse, not better. From the 8th onwards, the wind stays fresh to strong, and we see swell heights build back up. But the real kicker comes from the 12th of August onwards. We get a moderate energy (918 on the 12th) S groundswell with a very long 18-second period on Wednesday morning. That’s a proper groundswell, but the wind is 19 mph cross-on. Then on the 14th of August, we see the biggest swell of the period: 8 ft from the ENE at 8 seconds with strong 28 mph cross-shore wind. That’s 8 feet of messy, lumpy wind-slop with combined energy hitting 1021 – strong wave energy—but it’s just a washing machine. Paddling out in that strong breeze is a chore for nothing.
Honestly, there are zero standouts in this 16-day stretch. There’s not a single morning or afternoon where the stars align—no good wind, no quality swell direction, and the break is exposed to the wrong angle. If you’re desperate, Tuesday morning the 4th is your only whisper of a chance, but with cross-shore wind and questionable tides, it’s a long shot. For the rest of it, Halfpoint/Fullpoint is a total no-go. The setup looks more interesting for kite-surfing than paddle surfing, if I’m being honest.
Hang in there—this blank run can’t last forever.

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.
