The Lowdown
Alright, Rusty here again. Let's break it down in feet and miles.
First week is a bit of a snoozer. We’ve got small, so-so waves for the first several days, with a lot of cross-off wind but just not enough juice. Call it a five-day lull where you’re better off checking the tide charts than the surf forecast.
The real action kicks off on Saturday, the 1st of August. That morning at Ohara is the one to circle. We’re looking at a clean 3ft swell from the SSE, with a 12-second period and a combined energy of 512 – that’s solid, moderate energy. The wind is light and cross-off, so it’s gonna be glassy. This is the standout. The swell direction is exactly what this spot wants, and the conditions are set for a very good session. It’s inconsistent here, but when it comes, it’s worth it. Crowds are possible, so don’t be late.
Sunday the 2nd gets bigger. Swell hits 5ft from the S, with a 14-second period – that’s a very long period groundswell. The combined energy is a strong 1236. That’s expert territory, especially at a beach break where it might be a bit too straight. The wind stays cross-off, so it’ll be clean, but only for the experienced crew. Water temp is about 77°, which is average for the season.
The 3rd and 4th of August are still pumping with 5ft swell from the S and SSW, holding that strong energy (over 1000). The long period means it’ll be better for a point or reef, but for the brave, Ohara could still dish out some bombs. The wind stays cross-off, keeping it smooth.
After that, it drops off into the 5th, down to 3ft, and the energy fades. So, the call is: sit out the first week, then hammer the 1st of August for the best all-round conditions. The 2nd onwards is for the big-wave crew.
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.
