The Lowdown
Alright, grab your board. It’s Rusty here, and I’ve gotta be straight with you: the next couple of weeks are going to test your patience. There’s a real lack of decent surf on the horizon, but the ocean’s always got something up its sleeve, so let’s break it down.
The first week is a write-off. We’re looking at onshore and cross-shore winds that are just going to chop everything up. The swell direction is all over the shop, but the wind is the real killer. For the next seven days, you’re better off doing literally anything else. The water temp is sitting at a pretty normal 80°F, which is about average for this time of year, so it’s not like you’ll freeze waiting for a set.
We finally see a glimmer of hope around the 11th and 12th. A long-period south swell shows up, pushing through 3-4 feet. The energy jumps into the strong range (866), but that cross-shore wind is still going to mess it up. The period of 18 seconds is seriously long, so it’ll be lining up better at reefs and points than it will at the beach. But with that wind, even that’s going to be a battle.
The real action, if you can call it that, kicks off on Monday the 17th. We get a solid jump in size, with the swell pushing 10 feet and the energy going through the roof (1408). But here’s the catch: the period drops to a short 9 seconds, and that ENE wind is still howling at 25 mph. It’s big, but it’s sloppy. If you're an expert, this might be your window for some heavy, gnarly conditions, but it’s not going to be pretty.
Honestly, if you're not an expert, your best bet is to sit this one out. The constant strong cross-shore winds and messy conditions make the setup look far more interesting for kite surfing than paddle surfing. There’s plenty of swell, but not much that’s surfable.
If you’re holding out for a clean day, you might be waiting a while. The forecasts are always changing, so don't lose hope entirely, but as it stands, there’s nothing that’s worth a second look.
Stay tuned, keep your board waxed, and maybe take up fishing for a week.
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.
