The Lowdown
Alright folks, Rusty here with a look at the waves ahead for Middles/Generals.
Well, I gotta be straight with you – this is one of those outlooks where you might wanna take up golf for a bit. We’ve got a long, frustrating stretch of poor conditions to start. From Thursday the 27th of August all the way through to Sunday the 6th of September, it’s a write-off. Strong cross-shore winds, mainly from the ENE at 19-25 mph, are just chopping everything to bits. The swell is small and weak, with combined energy readings mostly between 475 and 929 (moderate wave energy), but that wind is the real killer. The water temp is sitting at 81°, which is about average for this time of year.
Finally, around Monday the 7th of September, things start to look a little more promising. We see the swell energy jump into the 1000s, peaking at 1580 on Thursday the 10th with an 8ft swell from the ENE. The wind backs off to a light breeze, turning cross-onshore, which will at least clean things up a bit. The waves will be solid and there's some real grunt in the water.
Now, the standout looks to be on Friday the 11th of September. The morning session could be special, with the swell hitting 10ft from the ENE, period around 9 seconds, and a light offshore wind from the ESE. That's the kind of wind that will really groom these waves. But there's a big caveat, and I mean a huge one: at 10ft, this is going to be a beast and only for the experts. This break is exposed to the ESE, which is the optimum direction, so it'll be handling that energy, but it'll be heavy and powerful. Combined wave energy hits 2105 (strong to very strong wave energy), so you’ll feel the ocean’s pulse. Expect crowds, as this spot is often busy when it's on.
The afternoon on the 11th drops back to 7ft, but the wind shifts cross-onshore, so the morning is the real window for the experienced crew.
Honestly, for the first week-plus, the setup looks more interesting for kite surfing than paddle surfing with that strong cross-shore wind. But that last few days, especially the morning of the 11th, has a real shot of being something special for the chargers.
This is Rusty, signing off.

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