The Lowdown
Alright, Rusty here. Let's talk about what we've got coming up for Halfpoint/Fullpoint.
Honestly, it's a bit of a rough stretch ahead. The first real chance to paddle out doesn't even show up until Wednesday afternoon, the 29th of July. The swell is there at 5ft from the ENE, with a moderate 645 energy, but the wind is a cross-shore and the forecast just calls it marginal. Water temp is 80°, which is about normal for this time of year, so no surprises there. It's something to look at, but not really a standout.
Honestly, from there, things go pretty darn ugly. The rest of July and the first few days of August are just a write-off. We're looking at a solid 10-day gap of poor surf conditions. The wind cranks from the ENE, sometimes hitting 28 mph, and it's all cross or cross-on shore, just tearing the surface apart. The swell gets bigger – up to 8ft by the 1st of August with a combined energy of 1379 – but with that strong wind and short 8-second period, it's just a messy, choppy, lumpy mess. At that size and with those conditions, it's really only for the experts, and even then, it's going to be a battle. The setup looks more interesting for kite surfing than paddle surfing on those days.
Eventually, the wind drops a little. Tuesday morning, the 4th of August, is the next time we see a marginal call. Still a cross-shore, but the swell is a bit cleaner at 5ft from the ENE with a longer 11-second period. The energy is still moderate at 629. It's something to check if you're desperate, but it's not good.
The pattern continues with nothing really clean. It's all cross-shore or cross-onshore breeze, with lumpy, choppy conditions. The only real shift we see is in the second week. Around the 10th of August, the swell direction swings to the SSW, with a long period of 16 seconds. This is a promising sign for the longer-term. That kind of groundswell with a long period tends to favour points and reefs, and Halfpoint/Fullpoint is exposed to the ESE, so a SSW swell might wrap in differently. But the wind is still messy. The best-looking window in that second week is the 10th of August (Monday morning). The swell is small at 3ft from the SSW, but the period is a very long 16 seconds, giving it a combined energy of 759. The wind is a moderate cross-shore, which isn't ideal, but it's the closest we get to a clean wave in the whole outlook. Keep in mind that a long period SSW swell can be a bit inconsistent and might break straight at a beach break, but it's the best option on offer.
So, to sum it up: the first 10 days are mostly a write-off with strong winds and poor conditions. The true standout, if you're patient, is the morning of the 10th of August. That's the one to circle on the calendar, but it's a long way out, so treat it as a promising idea rather than a guarantee. For now, the water’s fine, but the wind is not.
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.
