The Lowdown
G'day, Rusty here. Let's break down what's happening at Makaha over the next couple of weeks. We've got a nice run of small, clean waves coming through, ideal for a longboard or a funboard. Don't expect any huge sets, but for mornings with silky conditions, it's going to be a treat.
The water temp is right about average for this time of year, so nothing weird there. You'll be fine in a shorty or boardies.
Kicking off Wednesday the 19th of August. We start with a tiny 2ft swell from the SW, but the magic is in the wind. It's glassy. Dead calm at 3 mph from the east. The combined energy is moderate at 232, but for a summer morning, you can't beat these conditions. The swell has a very long period of 16 seconds, making it a proper groundswell, and at Makaha, a beach and reef setup, that means waves with real shape and power. Expect long waits between sets, making the paddle out easy. The afternoon goes glassy too with a 3 mph W wind, but the swell drops a touch.
Thursday the 20th starts clean with a 2ft SW swell and a very long 18-second period, but the wind is cross-off from the NNW at just 3 mph. The energy is up at 288, and it'll be clean. The afternoon gets a bit breezier with a 12 mph cross-off from the NNE, which is still fine.
Now for the real highlights. Look at Saturday the 22nd of August. Saturday morning we've got a 3ft SSW swell with a 16-second period, clean offshore wind from the NE at 6 mph, and energy climbing to 399. That's a solid little combo. The waves will be lined up and the conditions will be smooth as glass. This is the best session of the first week, no question. The afternoon stays clean with a moderate offshore and a 2ft SW swell.
Sunday the 23rd is another good morning with moderate offshores and a 2ft SSW swell, but the wind picks up to a fresh 18 mph by the afternoon, so that session gets tricky.
Looking further ahead, Thursday the 27th of August is a standout. We get a 3ft S swell with a 16-second period, gentle offshore winds from the ENE all day, and the morning energy hits 501 – that's strong. The waves will have some real punch, but still easy enough for most intermediates. This is the pick of the entire outlook. The swell direction from the south is working nicely with the optimum W direction, so expect some fun, shapey walls.
Thursday the 3rd of September looks poor with strong cross-off winds, but before that, Wednesday the 2nd of September morning is worth a paddle with a 3ft S swell and a moderate offshore. The period drops to 14 seconds, but it's still clean and has some push.
Overall, there are no real gaps in the action. The surf stays small but steady. If you want the cleanest, most user-friendly waves, point your board toward Makaha on Saturday the 22nd morning or Thursday the 27th morning. Classic summer surf on offer.

Information about the Makaha Surf forecast
The above surf forecast table for Makaha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Makaha can be found by selecting the local surf guide option on the grey menu. Our Makaha 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 (Makaha) 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 Makaha 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.
Makaha is 21 km (13 miles) from Makakilo City. If you plan a vacation in Oahu, look for hotels and other accommodation in Makakilo City. Makakilo City has rooms for a wide range of budgets as well as car hire and transport links.
