The Lowdown
Alright, Rusty here, let’s talk about what’s cookin’ at Ohara.
First off, the water temperature is sitting right around 80°, which is pretty much spot on for this time of year – no complaints there.
The next few days are a bit of a write-off, to be honest. We’ve got a mix of cross-off and onshore winds, some heavy rain, and the swell is pretty weak and short-period. Wednesday the 2nd is the only real bright spot early on with some clean, chest-high waves (3ft to 4ft) from the ESE, but the energy is only moderate (219-315). After that, Thursday through the following Tuesday is pretty grim. The wind goes onshore, it gets choppy, and the poor conditions just keep rolling in. There’s a nasty stretch from Thursday the 3rd all the way through to Tuesday the 8th where the surf is just not worth paddling out for.
Now, things start to get interesting around Wednesday the 9th. A solid SSE groundswell arrives, but it’s a big one – 8ft in the morning, jumping to 10ft in the afternoon. The wind is fresh offshore, which is a major positive, meaning clean, lined-up waves. But the period is 12-13 seconds, so this is a proper groundswell. The energy is strong (1472-3296). However, the swell is predicted to be too big for Ohara by the afternoon, so this is really only for the experts. The standouts here are the Wednesday morning (September 9th) and Thursday morning (September 10th) sessions. On Thursday, it’s a 13ft, 11-second swell from the S with a strong offshore breeze – massive, powerful, and clean. The combined energy is massive (5995). This is the big one, but it’s for the experienced crew only.
The following week, from Friday the 11th to Sunday the 13th, the size drops back to a more manageable 5ft to 7ft, with the wind staying offshore or cross-off. The standout is Saturday the 12th: a clear day, with a gentle offshore breeze and clean 5ft to 5ft SSE swell. The energy is moderate (442-605), and it’s looking like the best all-rounder for the intermediate surfer in the whole window.
Further out, Monday the 14th and Tuesday the 15th offer some good, clean waves in the 3ft to 6ft range with a very long 14-second period from the E. That long period means the wave quality will be excellent, but at a beach break like Ohara, it might break a little too straight. Still, the energy is solid (568-884), and the wind is light and off, so it’s worth looking at.
Then, on the 16th, we get another massive spike – 15ft from the SSE with a 14-second period. That’s an enormous amount of energy (7106). Again, the wind is offshore, but it’s way too big for this spot. That’s a hard pass for anyone but the most seasoned charger.
The last day in the forecast, the 17th, sees a drop-off in quality with a strong onshore wind and lumpy 8ft waves.
So, the best on offer? Thursday morning, September 10th for the big-wave experts, and Saturday, September 12th for the rest of us. That Saturday session is the one to circle.
Rusty out.

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.
