Alright, Rusty here. Let’s have a look at the next 16 days for Ohara.

First up, the water’s running about average for the time of year, sitting at 76°, so nothin’ unusual there. The outlook starts with a bit of a wait – nothing worthwhile on the cards until Sunday the 12th. That initial swell comes in with some serious grunt, a 7 ft SSW groundswell with a 16-second period. That’s a long-period groundswell, packing a heap of energy (2006). For a break like Ohara, which is exposed and inconsistent, that long period can mean the waves are gonna be a bit straight and fast, better suited to a reef or point, but it’s still a big, powerful swell. The wind is a cross-off, so it’ll be clean, but it’s a solid 16 mph. Sunday afternoon holds similar, 6 ft, still that long-period energy.

The real standout, the one you’d circle on the calendar, is Friday the 17th in the afternoon. That’s where the magic lines up. We’ve got a 3 ft SE swell, but the period jumps back to 16 seconds, and the energy is strong (560). The wind is a gentle cross-off breeze, keeping it clean. For a break that’s inconsistent, when it turns on like this, it can be a proper session. The optimum swell direction is SE, and here it is, bang on. Just be aware, crowds are *sometimes* an issue here, so you might have some company.

The second week gets a bit messy. Saturday the 18th still has size – 8 ft SE swell in the morning – but it’s a shorter period (12 seconds) with cross-shore wind, so it’ll be a bit lumpy. That’s expert territory at that size. After that, it’s a run of poor surf or very ordinary conditions until around Tuesday the 21st. That day shows some promise with a 4 ft ESE swell and a light cross-off wind, making for clean, surfable waves. Wednesday the 22nd afternoon is the pick of the later week, with a 4 ft ESE swell, 12-second period, and gentle offshore wind. The energy is moderate (523) and it’ll be clean. Thursday the 23rd keeps it going with a 4 ft ESE swell and light winds.

After that, it fades out into small, poor conditions, with a few pockets of surfable but ordinary waves over the weekend of the 26th. The last day, Monday the 27th, is another poor one with onshore wind. So, if you’re looking for the best, point your board at Friday afternoon the 17th, and keep an eye on Wednesday the 22nd.

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.
