The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a real mixed bag across the board at Ohara. The opening act is the standout, but after that, things get pretty grim for a long stretch.
Monday the 24th of August is your window. The early session is the pick of the entire 16-day run. We’re looking at a clean 3ft SSE groundswell with a very long period of 18 seconds. The energy is solid with a reading of 944, and with glassy, calm conditions, it’s going to be a special morning. This is a long period groundswell, so it will be better shaped and offer longer lulls between sets, but it can get a bit straight at beach breaks. The afternoon sees the swell jump to 6ft from the same SSE direction, but the wind swings to a moderate cross-off, so the quality drops off.
Tuesday the 25th and Wednesday the 26th see the swell holding around 5-6ft but with a shorter period and fresher cross-off winds. The magic is gone. From Thursday the 27th onwards, we hit a major dry spell. There’s a solid 8-day gap of poor to marginal conditions, with small, weak swells, funky wind directions, and a lot of cross-onshore chop. The energy drops to very low levels (e.g., 131), and there’s just nothing to get excited about. A few windows in early September offer some offshore wind, but the swell is tiny and inconsistent.
The next potential moment comes on Sunday the 6th of September. The afternoon session shows promise with a 5ft SSE swell at 13 seconds and a moderate offshore wind. The energy is strong at 1144, and the forecast is excellent for experienced surfers. This is a long-range call, so it’s promising but less certain. The following Monday afternoon also looks decent, with 4-5ft S swell and clean conditions.
The Takeaway: If you have one shot, make it Monday the 24th of August, early. You’ll be greeted by a clean, glassy 3ft SSE groundswell. It’s a long period wave, so look for a point or a reef to get the best out of it. After that, prepare for a long wait until the second week of September for the next real chance. The water temperature is about average for the time of year at Ohara.

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.
