The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s happening at Halfpoint/Fullpoint for the next couple of weeks. I’ll be straight with you – this stretch is a tough one.
Right off the bat, we’re looking at a long, dry spell. From now through to the end of July, the conditions are just not cooperating. The surf is there, but the wind is a constant problem. We’ve got a persistent cross-shore breeze, mostly from the ENE, blowing at 15 mph to 25 mph. That’s creating a lumpy, messy cross-chop that’s ruining any chance of a clean wave. The swell is mostly short-period stuff around 7 to 8 seconds, which doesn’t help. There’s a bit of a shift around the 21st and 22nd where we see some longer-period swell from the SSW, with periods hitting 20 to 23 seconds, and the wave energy climbs into the strong range, but the wind stays on it, cross and messy. It’s a real shame – you can see the energy in the water, but it’s a battle. The water temp is sitting at 80°, which is about average for the time of year.
The first real glimmer of hope doesn’t show up until late in the window. Starting around Sunday, July 27th, we see a shift. The swell swings around to the east, with heights building to 6 ft to 7 ft, and the period is a solid 15 to 17 seconds – that’s proper groundswell. The energy readings are very strong. That’s a lot of power. The problem is, the wind is still cross-shore, but it drops to a moderate breeze (15 mph). That’s better, but still not ideal. The waves will be a bit lumpy, but with that much energy and the longer period, the shape will be better. It’s a real case of “right idea, wrong wind.” The size on the 28th (7 ft) is getting into the expert-only zone, especially with that power.
The standout, if you can call it that, is likely the morning of Monday, July 28th. We’ve got a 7 ft east swell at 13 seconds, with a moderate cross-shore from the NE at 15 mph. The energy is still very strong. It’s not perfect, but it’s the best we’re going to get. The swell direction (E) is a good match for the optimum (ESE), so the break will be working. Keep in mind, this spot is a bit of a magnet for the crew – crowds are likely here.
After that, it fades again. The start of August brings back the messy, short-period ENE windswell and the strong cross-shore breezes. It’s a frustrating forecast for the Halfpoint/Fullpoint area. The later window has the power, but the wind just won't play ball. If you’re desperate, keep an eye on the 28th, but don’t get your hopes too high.
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.
