The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks at Ohara.
Things start off slow, but there’s some serious muscle building in the second week, especially if you’ve got the experience to handle it. The first few days are pretty flat and dirty, so if you can be patient, you’ll be rewarded.
Wednesday morning the 26th is the best we’ve got in the near term. You’re looking at a clean 4ft swell from the south with a light cross-offshore breeze. The water is sitting at 82°, which is a touch warmer than normal for this time of year – feels nice. Combined energy is moderate at 475. It’s surfable and clean, but this spot is inconsistent, so you’ll be waiting between sets. It’s exposed, and crowds are possible. Not a standout, but it’s the best of the first week.
After that, we hit a long dry spell. From Wednesday afternoon the 26th all the way through to Tuesday morning the 1st of September, the conditions just aren’t there. We’ve got smaller swell, wrong winds, and mostly poor conditions. There’s a tiny glimmer on Tuesday afternoon the 1st of September – a clean, gentle offshore wind with a 2ft south swell showing up, but it’s small.
Now, here’s where it gets interesting. Wednesday the 2nd of September brings a serious jump in energy. A very long period groundswell of 4ft to 4ft from the south-southwest with a 15-second period. The combined energy is strong to very strong (1144 and 1200). The wind is offshore and clean. But here’s the thing – with a period that long, this wave will be fat and lined up, better suited to a reef or point break, not a beach setup. It’s also over 5ft, so it’s pushing it for beginners. The forecast scores are marginal, but the energy is real. Keep an eye on it, but don’t call it a lock.
Then, the real standout period arrives on Monday the 7th and Tuesday the 8th of September. Monday morning the 7th sees a 8ft south swell with a 14-second period, and combined energy is massive at 2136. That’s strong to very strong. The wind is cross-offshore and clean. This is big, powerful, and definitely only for experts – over 8ft and too much for anyone not comfortable in heavy water. Tuesday the 8th of September is the pick of the whole window. You’ve got a 7ft south swell with a 12-second period, combined energy of 1371, and a gentle offshore wind from the south. The conditions are described as excellent for experienced surfers. This is the one to aim for. Clean, powerful, proper groundswell. The only catch is that this spot is inconsistent, so the sets may be spread out, but when they come, they’ll be worth the paddle.
The rest of the second week drops off – smaller swell and onshore winds creep back in by Wednesday the 9th. So if I were you, I’d be marking the calendar for Tuesday the 8th of September.
Stay salty,
Rusty

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