The Lowdown
Alright, Rusty here. Let's get straight into it, yeah? I've been lookin' hard at the charts for this stretch of coast, and I gotta be honest with you – it's a bit of a rough patch ahead. The whole 16-day window is a tough one. There's nothing that I'd call a great session, not even a good one. It's a long, dry spell. It's a solid run of "poor surf conditions" stamped all over the board.
The only spot on the menu is Makapu'u. It's a reef setup, so it's got that in its favour for holding a bit of shape, but the wind is the enemy here. From August 23 right through the first week and into the second, the wind is hammering straight onshore – a relentless, fresh to strong breeze from the ENE and NE, kickin' up chop and messin' up any chance of a clean face. For a spot that needs an offshore wind from the WSW, this is about as bad as it gets. The water temp is sitting at a pretty normal 81°F for this time of year, nothing unusual there, but you won't be enjoying it with that wind.
The combined swell energy starts off moderate, around 658 (moderate energy), and builds. By September 1, we start seeing strong energy numbers like 1335, and it keeps climbing. By September 6, the combined energy is blowing up past 2756 (very strong energy), with solid 10ft swell. But it's all wrong. The swell direction is from the ENE, which is nowhere near the break's optimum ESE. The period is short, around 7 to 8 seconds, meaning weak, wind-chopped, onshore slop. The one exception is a brief spike around August 27 where a long-period 18-second groundswell sneaks in from the south, but it’s barely 4ft and the ENE wind still wrecks it – total waste.
The best of a bad bunch? Look, there's no highlight. There's no standout. The whole period is a washout. This is a blank run that's normal for this area when the trades lock in like this. If you're absolutely desperate, the biggest, most powerful stuff hits around September 6 and 7, with 10ft swell and 12-second period from the ENE, but the combined energy of 2798 tells you it’s a beast. With that wind and that direction, that set-up looks more interesting for kite surfing than paddle surfing. Too much closeout, too much wind. For the rest of us, save your energy. The forecasts can always change, but right now, it's a no-go.
Stay dry, folks.
Rusty.

Information about the Makapu'u Surf forecast
The above surf forecast table for Makapu'u provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Makapu'u can be found by selecting the local surf guide option on the grey menu. Our Makapu'u 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 (Makapu'u) 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 Makapu'u 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.
Makapu'u is 13 km (8 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.
